In what year to do heart surgery. Types of heart operations - indications for performance. Differences in technique

Morning. Petroverigsky lane, 10. At this Moscow address in the Kitay-Gorod area, I arrived at the angiography.su federal center for the diagnosis and treatment of cardiovascular diseases, which is part of the state research center for preventive medicine, to put on a sterile suit again and visit in the operating room.

Angiography is a method of examining blood vessels using x-rays and contrast fluid. It is used to detect damage and defects. Without it, the operation that I am going to talk about - stenting - would not have been possible.

There will still be some blood. I think I should warn impressionable people about this before they open the post in its entirety.

Who has never heard of cholesterol plaques, he did not watch the show of Elena Malysheva. Plaques are deposits on the inner walls of blood vessels that have accumulated over the years. They are similar in texture to thick wax. The plaque consists not only of cholesterol, calcium in the blood sticks to it, making the deposits even more dense. And this whole structure slowly but surely clogs the vessels, preventing our fiery motor, or rather the pump, from delivering nutrients and oxygen to various organs, including the heart itself.

Before the advent of the stenting method, which will be discussed, the doctors were armed with only the surgical method of bypass surgery, which became popularly famous thanks to Boris Nikolayevich Yeltsin's heart surgery in 1996 in a round operating room. I remember this case vividly (a memory from childhood), although a lot of famous people have done a similar operation.

Shunting is an abdominal operation. A person is given anesthesia, they cut the chest (they cut it, they can’t do it with one scalpel), they stop the heart and start the artificial circulation system. The beating heart beats very strongly and interferes with the operation, so it has to be stopped. To get to all the arteries and shunt, you need to get the heart and turn it over. A shunt is a donor artery taken from the patient himself, for example, from the arm. A lot of stress on the body.

During stenting, the patient remains conscious (everything happens under local anesthesia), can hold his breath or take deep breaths at the request of the doctor. Blood loss is minimal, and the incisions are tiny, because the arteries are entered through a catheter, which is usually inserted into the femoral artery. And they put a stent - a mechanical vasodilator. All in all, an elegant operation (-:

The operation for Sergei Iosifovich was done in three stages. I ended up on the final operation in the series. You cannot place all stents at once.

The surgical table and the angiograph (a semicircular device hanging over the patient) form a single mechanism that works together. The table moves back and forth, and the machine rotates around the table to take x-rays of the heart from different angles.

The patient is placed on the table, fixed and connected to the heart monitor.

To make it clear the device of the angiograph, I will show it separately. It's a small angiograph, not as big as the ones in the operating room. If necessary, it can even be brought to the ward.

It works quite simply. An emitter is installed below, a converter is installed at the top (a smile is pasted on it), from which a signal with an image is already transmitted to the monitor. Scattering of X-rays in space does not actually occur, however, everyone present in the operating room is protected. About eight such operations are performed per day.

Through a vessel on the arm or thigh, as in our case, a special catheter is inserted.

A thin metal wire, a conductor, is inserted through the catheter into the artery to deliver the stent to the site of the blockage. I was amazed at its length!

The stent - a mesh cylinder - is attached to the end of this wire in a compressed state. It is mounted on a balloon that will be inflated at the right time to deploy the stent. Initially, this design is not thicker than the conductor itself.

This is what an open stent looks like.

And this is a scale model of a different type of stent. In the case when the walls of the vessels are damaged, they are installed with a membrane. They not only support the vessel in the open state, but also serve as the walls of the vessels.

All through the same catheter, an iodine-containing contrast agent is injected. With the blood flow, it fills the coronary arteries. This allows the x-ray to visualize them and calculate the blockage sites, on which stents will be placed.

Here is such an Amazon basin obtained by injecting contrast.

All eyes on monitors! The entire stent placement process is observed through X-ray television.

After the stent is delivered into place, the balloon on which it is attached must be inflated. This is done using a device with a manometer (pressure meter). This device, which looks like a large syringe, is visible in the photo with long conductor wires.

The stent expands and is pressed into the inner wall of the vessel. To ensure that the stent has expanded correctly, the balloon remains inflated for twenty to thirty seconds. It is then deflated and pulled out of the artery on a wire. The stent remains and maintains the lumen of the vessel.

Depending on the size of the affected vessel, one or more stents may be used. In this case, they are overlapped one after the other.

And here's how the stent works. Below are screenshots from the X-ray TV. In the first picture, we see only one artery, a curly one. But another one should be visible, below it. Because of the plaque, the blood flow is completely blocked.

The thick sausage on the second is a stent that has just been deployed. The arteries are not visible because the contrast is not running in them, but the wires are just visible.

The third one shows the result. An artery appeared, blood flowed. Now compare the first picture with the third one again.

The concept of expanding the affected areas of the vessel with the help of a certain frame was proposed by Charles Dotter forty years ago. The development of the method took a long time, the first operation using this technology was performed by a group of French surgeons only in 1986. And only in 1993, the effectiveness of the method was proven to restore the patency of the coronary artery and keep it in a new state in the future.

Currently, foreign companies have developed about 400 different models of stents. In our case, this is Cordis from Johnson & Johnson. Artem Shanoyan, head of the department of X-ray endovascular diagnostic and treatment methods at the center, answered my question about Russian stent manufacturers that they simply do not exist.

The operation takes about half an hour. A pressure bandage is applied to the puncture site. From the operating room, the patient is sent to the intensive care unit, and two hours later to the general ward, from where you can already scribble joyful SMS to relatives. And in a few days they will be able to see each other at home.

Lifestyle restrictions typical for heart patients are usually removed after stenting, the person returns to normal life, and observation is carried out periodically by a doctor at the place of residence.

The treatment of heart diseases using surgery is the field of surgery and cardiology, which is called cardiac surgery. To date, cardiac surgery is the most effective method of treating certain types of heart defects, coronary heart disease and helps prevent the development of myocardial infarction, as well as eliminate its consequences - aneurysms.
Surgical intervention is used only in cases where conservative methods of treatment cease to help and the patient's condition worsens. The untimely appeal of the patient to the doctor can also lead to heart surgery, when only surgical intervention remains the only way to help.

Today, cardiac surgery is one of the most actively developing and technically equipped branches of medicine. Every year, 700 patients undergo open heart surgery. The bulk of operations are in the United States. In Europe, the number of operations is 4 times less. In Asian countries, cardiac surgery is practically absent. In Russia, the number of heart surgeries is below the required minimum. This statistic is due to the fact that heart surgeries are expensive. In addition to open heart surgery, surgical intervention is also carried out without opening parts of the heart (for example, implantation of pacemakers, angioplasty).

Surgery is required for diseases such as:

1. Ischemic heart disease and its consequences (myocardial infarction);
2. Heart defects.
3. Violation of the heart rhythm.

Cardiac ischemia

Ischemic heart disease occurs as a result of insufficient blood supply to the working myocardium. The main cause of coronary heart disease is atherosclerosis (plaque formation on the walls of blood vessels). A slight narrowing of the lumen of the vessel leads to angina pectoris (a person feels pain only when the heart's need for oxygen is increased, for example, during exercise). A strong narrowing of the lumen of the vessel causes pain even at rest, and the duration of pain attacks can also become more frequent and increase - unstable angina. With a strong violation of the coronary blood flow, the death of the muscle fibers of the heart occurs - this is a myocardial infarction.

One of the severe complications of myocardial infarction is the formation of a post-infarction aneurysm of the left ventricle. An aneurysm is a bubble-like bulge. It is formed due to the fact that dead tissue is replaced by scar tissue, which in turn is not able to contract. Under the pressure of healthy contracting fibers, the scar tissue swells, part of the blood is retained in the ventricle in the area of aneurysmal expansion. With each contraction, organs and tissues receive less blood in an amount equal to the volume of the aneurysm. This is its main negative meaning. Very often, blood clots form in the aneurysm area, which can break off and be transferred with the blood flow to any organs, causing their heart attack (death of part or all of the organ). When a blood clot enters the brain, a stroke occurs.

Surgical intervention (heart surgery) for coronary heart disease is aimed at restoring the normal nutrition of all parts of the heart. The degree of damage to the coronary arteries will depend on what kind of operation should be done. An analysis of the state of the vessels is carried out using coronary angiography - this is an X-ray contrast research method that allows you to determine the location, nature and degree of narrowing of the coronary artery. Most often, stenting of the coronary artery, which causes pain, is done. In the case of severe atherosclerotic lesions of the coronary vessels, the patient needs coronary artery bypass grafting.

Types of surgery for coronary heart disease

Angioplasty and stenting of the coronary arteries

Angioplasty and stenosis is aimed at removing obstructions to blood flow by expanding the artery from the inside.
The operation is carried out as follows: with the help of special equipment, a catheter is inserted through a puncture in the thigh area under the control of a fluorographic preparation into the artery that feeds the heart. It must reach the site of narrowing of the artery, where a special balloon is inflated with a stent - a device that does not allow the artery to subside. The stent remains in the artery, and the catheter is brought out through the same hole in the thigh.

Coronary artery bypass grafting (ACS)

Coronary artery bypass grafting - restoring the blood supply to the heart muscle by creating a new blood flow path around the affected area of the coronary vessel using shunts - pieces of arteries or veins taken from the patient himself (for example, in the limb area). This operation is aimed at preventing myocardial infarction. To date, CABG operations are performed both with the use of a heart-lung machine and on a beating heart (cardiac immobility is only in the operated area).
One of the types of coronary artery bypass surgery is mammary coronary artery bypass grafting (MCB). The internal mammary artery is used as a shunt. The use of this vessel is beneficial, since in this case no additional incisions are needed due to the close location of the thoracic artery and the heart, and also because atherosclerotic plaques do not form in the artery, and therefore, the service life of such a shunt is quite long.

Plastic surgery of postinfarction aneurysm of the left ventricle

The essence of the intervention is to reduce the volume of the left ventricle by delimiting the area of aneurysmal expansion and the healthy part of the left ventricle. The surgeon removes the blood clots that have arisen in the area of the aneurysm, then sews a septum made of dense elastic human tissue across the cavity of the left ventricle. Two cavities are formed: one with normal, actively contracting walls, the other - from scar tissue that is not able to contract, but does not interfere with the normal functioning of the heart. Thus, blood circulation is restored and the risk of a blood clot breaking off is eliminated.

Heart defects

Heart disease is called defects in the structure of the heart, which lead to disruption of normal blood circulation, there is stagnation of blood in the pulmonary or systemic circulation.
The following violations are distinguished:

- stenosis (narrowing) of the valvular apparatus;
With valve stenosis, it stops passing the required volume of blood through the reduced opening.
- insufficiency of the valvular apparatus;
The valve leaflets cannot close tightly and allow blood to pass in the direction opposite to normal blood flow.

-defects of the interventricular and interatrial septum;
With defects in these partitions, blood enters from a cavity with high pressure into a cavity with less pressure, and venous blood, poor in oxygen, mixes with oxygenated arterial blood, which leads to oxygen starvation of tissues.
Heart defects can be congenital or acquired. Most of them do not require surgery. Sometimes the disease proceeds unnoticed by the patient. Congenital heart disease can disappear with age, but if this does not happen and signs of heart failure increase, then surgery is required.

Treatment of heart defects is aimed at correcting the existing mechanical defect in the functioning of the heart.

There are the following types of surgical intervention:

Prosthetics and plastic heart valves

Operations to install prostheses are performed on the open heart, using a heart-lung machine.
Valve prostheses are mechanical and biological.

Mechanical valves

Mechanical valves are made of metal and plastic. The validity period of such prostheses is about 80 years. However, when using them, a person has to take anticoagulants daily, since blood clots are easily formed on the prostheses, which contribute to the formation of blood clots. In rare cases, a breakdown of a mechanical prosthesis is possible, which most often leads to the death of the patient. Mechanical valve prostheses can be in the form
- rotating disk
The disc completely covers the hole, but is fixed at one end only. Blood moving in the right direction presses on the disc, turns it on the hinge and opens the hole; when the blood moves back, the disc completely covers the hole.
- built on the principle of a ball in a grid
The blood flow in the right direction pushes the ball out of the hole, pressing it to the bottom of the mesh and thereby creating the possibility of further passage of blood; the reverse flow pushes the ball into the hole, which is thus closed and does not allow blood to pass through.

biological valves

Biological prostheses, usually made from animal heart tissue, are considered more efficient. After their installation, treatment with anticoagulants, which have many contraindications, is not necessary. Such a prosthesis works from 10 to 20 years, its aging occurs gradually and you can prepare in advance for its replacement in a planned manner. Of course, in this case, a second operation is needed.
Biological valves do not require mandatory anticoagulation (although it is often recommended), but wear out faster than mechanical valves.

Plastic defects of the interatrial and interventricular septum

If the structure of the septum is violated, with a small defect (the size of the hole is not more than 3 cm), it is sutured, and with a significant size, a plastic patch is performed (using synthetic tissues or autopericardium)

Heart rhythm disorder

Cardiac arrhythmias are violations of the sequence, rhythm and frequency of contractions of the heart. Arrhythmias can occur as a result of metabolic disorders, for example, endocrine and autonomic, or the effects of certain drugs. They are also often caused by heart disease, and sometimes - intoxication.
The danger of arrhythmia is that it can lead to ventricular fibrillation (scattered contraction of fibers).
For the treatment of arrhythmias, drugs, catheter ablation, or a pacemaker (pacemaker) are implanted.

Surgical methods for the treatment of arrhythmias:

RF ablation

This is a minimally invasive surgical method that is used for:
- high heart rate with a pronounced pulse deficit;
- atrial fibrillation;
- progressive heart failure;
- supraventricular tachycardia.

The method of radiofrequency ablation consists in passing a special catheter to the area of the heart that causes an abnormal pathological rhythm. An electrical impulse is applied to this department, which destroys the tissue site that sets the wrong rhythm.
Ablation restores normal heart rhythm.

Pacemaker implantation

The operation is done in patients with heart rhythm disturbances that threaten life. The pacemaker aims to control and restore the normal contraction of the heart.
Doctors implant a special device under the skin or under the pectoral muscle. Two or three electrodes depart from the pacemaker, which are connected to the chambers of the heart to transmit an electrical impulse to them.

Defibrillator implantation

The principle of operation of a defibrillator is similar to a pacemaker. Its distinctive feature is the elimination of too fast and too slow heart rate. The heart rate is assessed using electrodes. Installing a defibrillator is similar to installing a pacemaker.

Installing a defibrillator is indicated for ventricular tachycardia.

Heart transplant

In critical cases, when the heart cannot perform its function and does not respond to any treatment, they resort to a heart transplant. Thanks to this operation, doctors prolong the life of the patient for a period of about 5 years. Research is currently underway to extend the life of people who have undergone heart transplants.

Postoperative recovery period

An important stage of recovery after surgery is the period of postoperative recovery. Strict monitoring of human health is necessary. This period is different and individual for each patient. Patients are prescribed special cardio training, diets. Emotional calm is needed.

Heart surgeries are dangerous due to their complications. The main signs of complications are fever, pain in the operated area, tachycardia, drop in blood pressure, shortness of breath. The ECG shows characteristic changes. The recovery period lasts six months - a year.

An example of monitoring the health of postoperative patients is the work of the doctor of medical sciences, professor, arrhythmologist Andrey Vyacheslavovich Ardashev. He does over 200 surgeries a year. Postoperative monitoring of patients began in 2011 with the help of the project. The doctor controls both the conclusion of the cardiovisor and the ECG itself in postoperative patients. Using the site service helps to monitor the recovery of the health of operated people via the Internet. This is a huge plus, since a large number of patients come to Moscow from all over Russia in order to have heart surgery. They pass the postoperative period already at home. Using the Cardiovisor allows you to take ECG readings at home and send them to the doctor using the site.

Heart valve replacement
- Possible complications and recommendations for care

Heart surgery is performed only when necessary. The most common of these are heart valve replacement and coronary artery bypass grafting. The first is necessary if the patient is concerned about valvular stenosis. It should be noted that heart surgeries pose a serious risk to the life of the patient, they are carried out with maximum precision and caution. Heart surgery sometimes leads to numerous problems and complications, in order to avoid this, you can use an alternative technique - valvuloplasty.

The procedure can replace replacement surgery, help normalize the activity of the heart muscles. In the process, a special balloon is inserted into the opening of the aortic valve, at the end this balloon is inflated. It is worth considering: if a person is in old age, valvuloplasty does not give a lasting effect.

Heart valve replacement

To decide on such a procedure, it is necessary to establish a diagnosis.

The operation is carried out immediately or some time after the test.

In some situations, the results indicate that a person needs bypass surgery. Valve replacement is an open procedure that can be performed using minimally invasive surgery. It should be remembered that heart valve replacement is a very complicated procedure, despite this, it is carried out very often.

Stages of the procedure and further rehabilitation

First you need to open the chest. Next, the doctor connects the patient to a special apparatus that provides artificial circulation. The device temporarily replaces the heart. The patient's circulatory system is connected to the device, after which the natural valve is removed and replaced. When this manipulation is completed, the device is turned off. In most cases, heart surgery goes well, but a scar forms on the organ.

After recovery from anesthesia, the breathing tube is removed from the lungs. If you want to remove excess fluid, such a tube should be left for a while. After a day, it is allowed to drink water and liquid, you can walk only after two days. After such an operation, pain in the chest area can be felt, and on the fifth day the patient is completely discharged. If there is a risk of complications, the hospital stay must be extended by 6 days.

Can there be complications after valve replacement?

A person can face such problems at different stages of the disease. During the operation, there is a risk of heavy bleeding, in addition, difficulties with anesthesia may arise. Possible risk factors include internal bleeding, seizures, possible infections. A heart attack can also happen, but this happens very rarely. As for the greatest danger, it lies in the appearance of tamponade of the pericardial cavity. This phenomenon occurs when blood fills its heart sac. This causes serious malfunctions in the functioning of the heart. Operations on the heart cannot but affect the general condition of a person. During the rehabilitation period, strict medical supervision is required. The need to visit the surgeon arises after 3-4 weeks after the operation. It is important to maintain the general well-being of the patient. An optimal dose of physical activity should be prescribed, it is important to stick to a diet.

What is coronary artery bypass grafting?

Coronary artery bypass grafting is a type of surgery that restores blood flow in the arteries. The procedure is necessary to eliminate coronary heart disease. The disease manifests itself when the lumen of the coronary vessels narrows, as a result of which an insufficient amount of oxygen enters the heart muscle. Coronary artery bypass surgery aims to prevent changes in the myocardium (heart muscle). After the operation, he should fully recover and contract better. It is necessary to restore the affected area of the muscle, for this the following procedure is carried out: everyday shunts are applied between the aorta and the coronary vessel that is affected. Thus, the formation of new coronary arteries occurs. They are designed to replace the narrowed ones. After the shunt is applied, blood from the aorta flows through a healthy vessel, thanks to which the heart produces a normal blood flow.

Back to index

What is the operation for?

This procedure will be required if the left coronary artery of the vessel that provides flow to the heart is affected. It is also needed if all coronary vessels are damaged. The procedure can be double, triple, single - it all depends on how many shunts the doctor needs. With coronary heart disease, the patient may need one shunt, in some cases two or three. Bypass surgery is a procedure that is often used for atherosclerosis of the heart vessels. This happens when angioplasty is not possible. As a rule, a shunt can serve for a long time, its functional suitability is 12-14 years.

Carrying out coronary artery bypass grafting

The duration of the operation is 3-4 hours. The procedure requires maximum concentration and attention. The doctor needs to gain access to the heart, for this it is necessary to dissect the soft tissues, then open the sternum and perform a stenotomy. During the operation, a procedure is carried out that is necessary for temporary, it is called cardioplegia. The heart must be cooled with very cold water, then a special solution should be injected into the arteries. To attach shunts, the aorta must be temporarily blocked. To do this, it is necessary to pinch it and connect the heart-lung machine for 90 minutes. Plastic tubes should be placed in the right atrium. Next, the doctor performs procedures that contribute to the flow of blood into the body.

What is routine vascular bypass surgery? This method involves the implantation of special implants into the coronary vessels outside the obstruction, the end of the shunt is sutured to the aorta. In order to be able to use the internal mammary arteries, it is necessary to carry out the procedure with the expenditure of more time. This is due to the need to separate the arteries from the chest wall. Upon completion of the operation, the doctor carefully fastens the chest, for this a special wire is used. With its help, a soft tissue incision is sutured, then drainage tubes are applied to remove residual blood.

Sometimes bleeding occurs after the operation, it continues throughout the day. The installed drainage tubes should be removed after 12-17 hours after the procedure. At the end of the operation, the breathing tube must be removed. On the second day, the patient can get out of bed and move around. Restoration of the heart rhythm takes place in 25% of patients. As a rule, it lasts for five days. As for arrhythmia, this disease can be eliminated within 30 days after surgery, for this conservative methods of therapy are used.

Let's try to lift the veil of the mystery of their work and find out what types of heart surgeries exist and are carried out today. Is it also possible to perform heart surgery without opening the chest?

When the heart is in the palm of your hand or open surgeries

Open heart surgery is so called because the cardiac surgeon "opens" the patient's chest, cuts through the sternum and all soft tissues, and makes an opening of the chest. Such interventions, as a rule, are performed with the connection of a heart-lung machine (hereinafter referred to as AIC), which is a temporary replacement for the heart and lungs of the operated person. This apparatus is a complex device of rather impressive dimensions, which continues to pump blood through the body when the patient's heart is artificially stopped.

Thanks to AIC, open-heart surgery can be extended for many hours if necessary. Open surgeries are used for valve replacement, coronary artery bypass grafting can also be performed in this way, many heart defects are eliminated by open interventions. It should be noted that AIC is not always used during their implementation.

The body can not always tolerate the intervention of a foreign heart substitute: the use of AIC is fraught with complications such as renal failure, impaired cerebral blood flow, inflammatory processes, and impaired blood rheology. Therefore, some operations on the open heart are carried out in the conditions of his work, without the connection of the AIC.

Such interventions on a beating heart include coronary artery bypass grafting, during this operation on a beating heart, the area of \u200b\u200bthe heart that the surgeon needs is temporarily switched off from work, and the rest of the heart continues to work. Such manipulations require high qualifications and skills of the surgeon, and also have a much lower risk of complications, they are perfect for people over 75 years old, patients with a large arsenal of chronic diseases, patients with diabetes mellitus than operations on an organ that is turned off from the blood circulation.

But all the pros and cons, of course, are determined by the cardiac surgeon. Only the doctor decides to keep the heart working, or stop it for a while. Open surgeries are the most traumatic, having a higher percentage of complications; after surgery, a scar remains on the patient's chest. But sometimes only such an operation can save a person's life, improve his health, return him to a full, happy life.

Intact heart or closed surgeries

If the sternum, heart chambers and the heart muscle itself were not opened during surgery, then these are closed heart surgeries. During such operations, the surgical scalpel does not affect the heart, and the surgeon's work consists in the surgical treatment of large vessels, cardiac arteries and aorta, the chest is also not opened, only a small incision is made on the chest.

Thus, a pacemaker can be installed, heart valve correction, balloon angioplasty, shunting, vascular stenting can be performed. Closed operations are less traumatic, have a lower percentage of complications, unlike open ones. Closed vascular surgery can often be the first step before subsequent heart surgery.

Indications for their conduct is always determined by the doctor.

Achievements of modern cardiac surgery or minimally invasive operations

Cardiac surgery is steadily moving forward, and an indicator of this is the increasing percentage of low-traumatic, high-tech manipulations that allow you to get rid of the pathology of the heart and blood vessels with minimal intervention and impact on the human body. What are minimally invasive interventions? These are surgical operations performed by introducing instruments or special devices, through mini-accesses - 3-4 cm incisions, or without incisions at all: during endoscopic operations, incisions are replaced by punctures.

When performing minimally invasive manipulations, the path to the heart and blood vessels can lie through the femoral vessels, for example - these operations are called endovascular, they are performed under x-ray control. Elimination of congenital malformations, prosthetic heart valves, all operations on vessels (from removal of a blood clot to expansion of the lumen) - all these interventions can be performed using minimally invasive technologies. Emphasis is placed on them in modern cardiac surgery, since a low risk of complications, minimal impact on the body are those huge advantages that patients can appreciate literally on the operating table.

Anesthesia during endoscopic procedures is not required, it is enough just to anesthetize the puncture site. Recovery after heart surgery performed using a minimally invasive technique is ten times faster. Such methods are also indispensable in diagnostics - coronary angiography, a method for examining the vessels of the heart by introducing contrast and subsequent x-ray control. In parallel with the diagnosis according to the indications, the cardiac surgeon can also perform therapeutic manipulations on the vessels - the installation of a stent, balloon dilation in a narrowed vessel.

And diagnosis and treatment by puncture on the femoral artery? Isn't this a miracle? Such miracles for cardiac surgeons are becoming routine. The contribution of endovascular methods of treatment is also invaluable in cases where the threat to the life of the patient is especially acute and minutes count. These are situations of acute coronary syndrome, thromboembolism, aneurysm. In many cases, the availability of the necessary equipment and qualified personnel can save the lives of patients.

When is the operation indicated?

It is up to an experienced cardiac surgeon or a council of doctors to decide whether an operation is indicated, as well as to determine the type of surgical intervention on the heart and blood vessels. The doctor can make a conclusion after a thorough examination, familiarization with the history of the development of the disease, monitoring the patient. The doctor should know the ins and outs of the disease very well: how long the patient has been suffering from cardiac pathology, what medications he takes, what chronic diseases he has, when he felt worse ... After evaluating all the pros and cons, the doctor makes his verdict: whether to have surgery or not. If the situation develops according to the above scheme, then we are dealing with a planned cardiac surgery.

It is shown to the following people:

lack of effect from adequate drug therapy;
rapidly progressive deterioration of well-being against the background of ongoing treatment with pills and injections;
severe arrhythmias, angina pectoris, cardiomyopathy, congenital and acquired heart defects requiring correction.

But there are situations when there is no time for reflection, questioning and analysis of the medical history. We are talking about life-threatening conditions - a blood clot broke off, an aneurysm exfoliated, a heart attack occurred. When the time goes by for minutes, emergency cardiac surgery is performed. Stenting, coronary artery bypass grafting, thrombectomy of the coronary arteries, radiofrequency ablation can be performed urgently.

Consider the most common types of heart surgery

CABG - coronary artery bypass grafting "on hearing" in many, probably because it is performed for coronary heart disease, which is extremely common among the population. CABG can be performed both open and closed, and combined techniques with endoscopic inclusions are also performed. The essence of the operation is to create bypass routes of blood flow through the vessels of the heart, restoring normal blood supply to the myocardium, which leads to a better supply of oxygen to the heart muscle.
RFA - radiofrequency ablation. This type of surgical intervention is used to eliminate persistent arrhythmias, when drug therapy is powerless in the fight against arrhythmias. This is a minimally invasive intervention, which is performed under local anesthesia, a special conductor is inserted through the femoral or subclavian vein, which supplies an electrode to the focus of pathological impulses in the heart, the current flowing through the electrode to the pathological focus destroys it. And the absence of a focus of pathological impulses means the absence of arrhythmia. 12 hours after the manipulation, the patient is already allowed to get up.
Prosthetic or plastic heart valves. Prosthetics means complete valve replacement, the prosthesis can be mechanical or biological. And plastic implies the elimination of defects in the "native" valve or valve apparatus. There are certain indications for these interventions, which are clearly known to cardiac surgeons.
Installing a pacemaker. Cardiac arrhythmias, severe bradycardia may be indications for installation, which, thanks to modern technology, can also be performed endoscopically.

Cardiac surgery is a branch of medicine dedicated to the surgical treatment of the heart. With pathologies of the cardiovascular system, such intervention is an extreme measure. Doctors try to restore the patient's health without surgery, but in some cases only cardiac surgery can save the patient. Today, this field of cardiology uses the latest advances in science to return the patient to health and a fulfilling life.

Indications for operations

Invasive interventions on the heart is a complex and risky job, it requires skill and experience, and the patient - preparation and implementation of recommendations. Since such operations are risky, they are carried out only when absolutely necessary. In most cases, the patient is trying to rehabilitate with the help of medicines and medical procedures. But in cases where such methods do not help, heart surgery is needed. Surgical intervention is carried out in a hospital and complete sterility, the operated is under anesthesia and the control of the surgical team.

Such interventions are needed for congenital heart defects or acquired. The former include pathologies in the anatomy of the organ: defects in valves, ventricles, impaired blood circulation. Most often they are discovered even during the bearing of a child. Heart disease is also diagnosed in newborns, often such pathologies need to be eliminated urgently in order to save the life of the baby. Among the acquired diseases, ischemic disease is in the lead, in this case, surgery is considered the most effective method of treatment. Also in the heart area there are: impaired blood circulation, stenosis or valve insufficiency, heart attack, pericardial pathology and others.

Heart surgery is prescribed in situations where conservative treatment does not help the patient, the disease progresses rapidly and threatens life, with pathologies that require urgent and urgent correction, and in advanced forms of diseases, a late visit to the doctor.

The decision on the appointment of the operation is made by a council of doctors or. The patient must be examined to establish an accurate diagnosis and type of surgical intervention. They identify chronic diseases, stages of the disease, assess the risks, in which case they talk about a planned operation. If emergency assistance is needed, for example, when a blood clot is torn off or an aneurysm is exfoliated, minimal diagnostics are performed. In any case, the function of the heart is restored surgically, its departments are rehabilitated, blood flow and rhythm are normalized. In severe situations, the organ or its parts are no longer amenable to correction, then prosthetics or transplantation is prescribed.

Classification of heart operations

In the area of the heart muscle, there can be dozens of different diseases, these are: insufficiency, narrowing of the lumen, ruptures of blood vessels, stretching of the ventricles or atria, purulent formations in the pericardium, and much more. To solve each problem, surgery has several types of operations. They are distinguished by urgency, effectiveness and method of influencing the heart.

The general classification divides them into operations:

Buried - used to treat arteries, large vessels, aorta. During such interventions, the chest of the operated person is not opened, the heart itself is also not affected by the surgeon. Therefore, they are called "closed" - the heart muscle remains intact. Instead of a strip opening, the doctor makes a small incision in the chest, most often between the ribs. Closed types include: shunting, balloon angioplasty, stenosis of blood vessels. All these manipulations are designed to restore blood circulation, sometimes they are prescribed to prepare for a future open operation.
Open - carried out after opening the sternum, sawing the bones. The heart itself during such manipulations can also be opened to get to the problem area. As a rule, for such operations, the heart and lungs must be stopped. To do this, connect the heart-lung machine - AIC, it compensates for the work of "disabled" organs. This allows the surgeon to accurately perform the work, in addition, the procedure under the control of AIC takes longer, which is necessary when eliminating complex pathologies. During open operations, AIC may not be connected, but only the desired zone of the heart can be stopped, for example, during coronary artery bypass grafting. Opening the chest is necessary to replace valves, prosthetics, and eliminate tumors.
X-ray surgery - similar to a closed type of operation. The essence of this method is that the doctor moves a thin catheter through the blood vessels, and gets to the very heart. The chest is not opened, the catheter is placed in the thigh or shoulder. The catheter is injected with a contrast agent that stains the vessels. The catheter is advanced under X-ray control, the video image is transmitted to the monitor. Using this method, the lumen in the vessels is restored: at the end of the catheter there is a so-called balloon and a stent. At the site of narrowing, this balloon is inflated with a stent, restoring the normal patency of the vessel.

The safest are minimally invasive methods, that is, X-ray surgery and a closed type of surgery. With such work, the risk of complications is the least, the patient recovers faster after them, but they can not always help the patient. Complex operations can be avoided with periodic inspections. The earlier the problem is identified, the easier it is for the doctor to solve it.

Depending on the condition of the patient, there are:

planned operation. It is carried out after a detailed examination, within the agreed time frame. A planned intervention is prescribed when the pathology does not pose a particular danger, but it cannot be postponed.
Urgent - these are operations that need to be done in the next few days. During this time, the patient is prepared, all the necessary studies are carried out. The date is set immediately after receiving the necessary data.
Emergency. If the patient is already in serious condition, the situation may worsen at any time - an operation is prescribed immediately. Before her, only the most important examinations and preparations are carried out.

In addition, surgical care can be radical or auxiliary. The first implies the complete elimination of the problem, the second - the elimination of only part of the disease, improving the patient's well-being. For example, if a patient has a pathology of the mitral valve and stenosis of a vessel, the vessel is first restored (auxiliary), and after a while valve plastic surgery (radical) is prescribed.

How operations are done

The course and duration of the operation depends on the pathology being eliminated, the patient's condition, and the presence of concomitant diseases. The procedure can take half an hour, and can stretch for 8 hours or more. Most often, such interventions last 3 hours, are carried out under general anesthesia and AIC control. First, the patient is prescribed an ultrasound of the chest, urine and blood tests, an ECG, and a consultation with specialists. After receiving all the data, they determine the degree and place of the pathology, decide whether there will be an operation.

As part of the preparation, a low-fat, spicy, and fried diet is also prescribed. For 6-8 hours before the procedure, it is recommended to refuse food and drink less. In the operating room, the doctor assesses the well-being of the ward, introduces the patient into a medical sleep. With minimally invasive interventions, local anesthesia is sufficient, for example, during X-ray surgery. When anesthesia or anesthesia takes effect, the main actions begin.

Heart valve repair

There are four valves in the heart muscle, all of which serve as a passage for blood from one chamber to another. The most commonly operated valves are the mitral and tricuspid valves, which connect the ventricles to the atria. Stenosis of the passages occurs with insufficient expansion of the valves, while the blood does not flow well from one department to another. Valve insufficiency is a poor closure of the cusps of the passage, while there is an outflow of blood back.

Plastic surgery is carried out open or closed, during the operation, special rings or sutures are applied manually along the diameter of the valve, which restore the normal lumen and narrow the passage. Manipulations last an average of 3 hours; with open views, an AIC is connected. After the procedure, the patient remains under the supervision of doctors for at least a week. The result is normal blood circulation and functioning of the heart valves. In severe cases, native leaflets are replaced with artificial or biological implants.

Elimination of heart defects

In most cases, defects are congenital, the cause of this can be hereditary pathologies, bad habits of parents, infections and fever during pregnancy. At the same time, children may have various anatomical abnormalities in the region of the heart, often such anomalies are poorly compatible with life. The urgency and type of surgery depends on the condition of the child, but they are often prescribed as early as possible. For children, heart surgery is performed only under general anesthesia, and under the supervision of medical equipment.

At an older age, heart defects develop with defects in the interatrial septum. This happens with mechanical damage to the chest, infectious diseases, due to concomitant heart disease. To eliminate such a problem, an open operation is also needed, more often with artificial cardiac arrest.

During manipulations, the surgeon can “patch” the septum with a patch, or suture the defective part.

Shunting

Coronary artery disease (CHD) is a very common pathology that affects mainly the generation over 50 years of age. Appears due to impaired blood flow in the coronary artery, which leads to oxygen starvation of the myocardium. There is a chronic form, in which the patient has constant attacks of angina pectoris, and an acute one is a myocardial infarction. They try to eliminate chronic pain conservatively or with the help of minimally invasive techniques. Acute requires urgent intervention.

To prevent complications or alleviate the disease, apply:

aorto-coronary bypass;
balloon angioplasty;
transmyocardial laser revascularization;
stenting of a coronary artery.

All these methods are aimed at restoring normal blood flow. As a result, enough oxygen is supplied to the myocardium with blood, the risk of a heart attack is reduced, and angina pectoris is eliminated.

If you need to restore normal patency, angioplasty or stenting is enough, in which the catheter is moved through the vessels to the heart. Before such an intervention, coronary angiography is performed to accurately determine the blocked area. Sometimes blood flow is restored bypassing the affected area, while a bio-shunt (often a section of the patient's own vein from the arm or leg) is sutured to the artery.

Recovery after interventions

After surgery, the patient remains in the hospital for another 1-3 weeks, all this time the doctors will assess his condition. The patient is discharged after verification and approval by the cardiologist.

The first month after surgical procedures is called the early postoperative period, at this time it is very important to follow all the doctor's recommendations: diet, calm and measured lifestyle. Nicotine, alcohol, junk food and physical activity are prohibited regardless of the type of intervention.

The doctor's recommendations should also contain a warning about the dangers and complications. At discharge, the doctor will set the date for the next appointment, but you need to seek help and unscheduled if the following symptoms occur:

sudden fever;
redness and swelling at the incision site;
discharge from the wound;
persistent chest pain;
frequent dizziness;
nausea, bloating and stool disorders;
breathing difficulties.

At scheduled examinations, the cardiologist will listen to the heartbeat, measure the pressure, and listen to complaints. To check the effectiveness of the operation, ultrasound, computed tomography, x-ray examinations are prescribed. Such visits are scheduled once a month for six months, then the doctor will see you once every 6 months.

Often, in addition to surgical care, medications are prescribed. For example, when prosthetic valves are artificially implanted, the patient drinks anticoagulants for life.

In the postoperative period, it is important not to self-medicate, since the interaction of permanent drugs and other medications can give a negative result. Even conventional painkillers need to be discussed with. To keep fit and restore health faster, it is recommended to be outdoors more often, walk on foot.

Life after heart surgery will gradually return to its previous course, a full recovery is predicted within a year.

Cardiac surgery offers many methods for the rehabilitation of the heart. Such operations are designed to restore the patient's physical and moral strength. You should not be afraid or avoid such procedures, on the contrary, the sooner they are carried out, the greater the chances of success.
