What are heart surgeries? Open heart surgery What year to do heart surgery

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.

How are operations performed?

An operation is an intervention in the human body with a violation of its integrity. Each disease requires an individual approach, which naturally affects the way the operation is performed.

How heart surgery is done: preparation for surgery

Heart surgery (cardiac surgery) is one of the most difficult to perform, dangerous and responsible type of surgical intervention.

Planned operations are usually carried out in the morning. Therefore, the patient is not allowed to eat or drink in the evening (for 8-10 hours), and immediately before the operation, a cleansing enema is made. This is necessary in order for the anesthesia to work as it should.

The place where operations are performed must be sterile. In medical institutions, special rooms are used for these purposes - operating rooms, which are regularly sterilized by quartz treatment and special antiseptics. In addition, all medical personnel who take part in the operation wash themselves before the procedure (you even have to rinse your mouth with an antiseptic solution), and also change into special sterile clothes, put on sterile gloves on your hands.

The patient is also put on shoe covers, a cap on his head, and the operation field is treated with an antiseptic. If necessary, before the operation, the patient's hair is shaved if the surgical field is covered with it. All these manipulations are necessary to avoid infection of the surgical wound with bacteria or other dangerous active microorganisms.

Narcosis or anesthesia

Anesthesia is a general anesthesia of the body with its immersion in drug-induced sleep. During surgical interventions on the heart, general anesthesia is used, and in some cases, during endovideosurgical operations, spinal anesthesia, in which a puncture is made into the spinal cord at the level of the lower back. Substances that cause pain relief can be administered in various ways - intravenously, through the respiratory tract (inhalation anesthesia), intramuscularly or in combination.

Course of open heart surgery

After the person goes into medical sleep and ceases to feel pain, the operation itself begins. The surgeon uses a scalpel to open the skin and soft tissues on the chest. Cardiac surgery may also require an “opening” of the chest. To do this, with the help of special surgical instruments, the ribs are sawn. Thus, doctors “get” to the operated organ and put special dilators on the wound, which provide better access to the heart. Junior medical staff, using suction, removes blood from the surgical field, and also cauterizes cut capillaries and blood vessels so that they do not bleed.

If necessary, the patient is connected to an artificial heart machine, which will temporarily pump blood through the body, while the operated organ is artificially suspended. Depending on what kind of heart surgery is performed (what kind of damage is eliminated), appropriate manipulations are carried out: it can be the replacement of blocked coronary arteries, the replacement of heart valves in case of defects, vein bypass surgery or the replacement of an entire organ.

Extreme care is required from the surgeon and all staff, as the life of the patient depends on it. It should also be added that during the operation, blood pressure and some other indicators are constantly monitored, which indicate the patient's condition.

Endovideosurgery: stenosis and angioplasty

Today, more and more often, heart surgery is performed not by an open method - with a chest incision, but with access through the femoral artery on the leg, under the control of an X-ray machine and a microscopic video camera. After preparing for operation, which is similar for all types of surgical interventions, and putting the patient into a medical sleep, access to the femoral artery is opened through an incision in the leg. A catheter and a probe with a video camera at the end are inserted into it, thanks to which access to the heart is provided.

In this way, angioplasty with stenosis of blood vessels is carried out in cardiac surgery, which is necessary for blockage of the coronary vessels that feed the heart itself with blood. Special stands are installed in the narrowed vessels - cylindrical implants that do not allow the arteries to clog anymore, which prevents the possibility of developing coronary disease.

After the main part of the operation is over and the heart is on its own again functions, stitching of damaged nerves, vessels and tissues is performed. The wound is again treated with an antiseptic, the surgical field is closed, soft tissues and skin are sutured with special threads. A medical bandage is applied to the external wound. After the end of all these procedures, the patient is taken out of anesthesia.

Other types of transactions

In addition to the abdominal operations described above, there are also operations performed in a less traumatic way:

Laparoscopy - is performed using a laparoscope, which is inserted through 1-2 cm incisions in the skin. Most often used in gynecology, gastrectomy and other operations in the abdominal cavity. You can read more about this
Laser surgery - is carried out using a special laser beam. Usually, operations are performed in this way on the eyes, when removing skin formations, etc. You can read more about the method

Heart surgery helps to cure many diseases of the cardiovascular system that are not amenable to standard therapeutic methods. Surgical treatment can be carried out in different ways, depending on the individual pathology and the general condition of the patient.

Indications for surgical treatment

Cardiac surgery is a field of medicine in which physicians specialize in studying, inventing methods and performing operations on the heart. The most complex and dangerous cardiac surgery is heart transplantation. Regardless of what type of surgery will be performed, there are general indications:

the rapid progress of the disease of the cardiovascular system;
ineffectiveness of conservative therapy;
untimely visit to the doctor.

Heart surgery makes it possible to improve the general condition of the patient and eliminate the symptoms that disturb him. Surgical treatment is carried out after a complete medical examination and the establishment of an accurate diagnosis.

Do operations for congenital heart defects or acquired. A congenital defect is detected in a newborn immediately after birth or before birth on an ultrasound examination. Thanks to modern technologies and techniques, in many cases it is possible to detect and cure heart disease in newborns in time.

An indication for surgical intervention can also be coronary disease, which is sometimes accompanied by such a serious complication as myocardial infarction. Another reason for surgery may be a violation of the heart rhythm, since this disease tends to cause ventricular fibrillation (scattered contraction of fibers). The doctor should tell the patient how to properly prepare for heart surgery in order to avoid negative consequences and complications (such as a blood clot).

Advice: proper preparation for heart surgery is the key to a successful recovery of the patient and prevention of postoperative complications, such as a blood clot or occlusion of the vessel.

Operation types

Cardiac surgeries can be performed on an open heart as well as on a beating heart. Closed heart surgery is usually performed without affecting the organ itself and its cavity. Open heart surgery involves opening the chest and connecting the patient to a ventilator.

During open heart surgery, a temporary cardiac arrest is performed for several hours, which allows you to perform the necessary manipulations. This technique makes it possible to cure complex heart disease, but is considered more traumatic.

Surgery on a beating heart uses special equipment so that the heart continues to contract and pump blood during surgery. The advantages of this surgery include the absence of such complications as embolism, stroke, pulmonary edema, etc.

There are the following types of heart operations, which are considered the most common in cardiology practice:

radiofrequency ablation;
coronary artery bypass grafting;
valve prosthetics;
Operation Glenn and Operation Ross.

If surgery is performed with access through a vessel or vein, endovascular surgery (stenting, angioplasty) is used. Endovascular surgery is a branch of medicine that allows for surgical intervention under X-ray control and using miniature instruments.

Endovascular surgery makes it possible to cure the defect and avoid the complications that abdominal surgery gives, helps in the treatment of arrhythmias and rarely gives such a complication as a thrombus.

Advice: Surgical treatment of heart pathologies has its advantages and disadvantages, therefore, the most suitable type of operation is selected for each patient, which carries fewer complications for him.

Radiofrequency or catheter ablation (RFA) is a minimally invasive surgical intervention that has a high therapeutic effect and minimal side effects. Such treatment is shown for atrial fibrillation, tachycardia, heart failure and other cardiac pathologies.

By itself, arrhythmia is not a serious pathology requiring surgical intervention, but can lead to serious complications. Thanks to RFA, it is possible to restore a normal heart rhythm and eliminate the main cause of its violations.

RFA is performed using catheter technology and under X-ray control. Heart surgery takes place under local anesthesia and consists in bringing a catheter to the necessary part of the organ, which sets the wrong rhythm. Through an electrical impulse under the action of RFA, the normal rhythm of the heart is restored.

May God grant everyone to live a long life so that the surgeon's scalpel never touches his heart. However, not always cardiac surgery can be replaced by therapy.

When is surgery necessary?

When conservative therapy does not give the desired result.
When, despite all the ongoing treatment, the patient's condition continues to deteriorate.
When there are severe congenital heart defects, severe arrhythmia, cardiomyopathy.

By urgency, cardiosurgical operations are emergency and planned.

Emergencies are carried out when a person's life is in serious danger. This happens when a myocardial infarction occurs, a blood clot suddenly breaks off, or aortic dissection begins. They do not tolerate delay in surgery when the heart is injured. The consequences of delay are severe.
Planned are carried out in accordance with the developed plan for the correction of the patient's health. The date of the operation may be postponed depending on the circumstances. For example: with a cold, to avoid additional stress on the heart, or when the pressure suddenly dropped.

Surgical intervention differs in the technique of execution. There are such types of heart operations:

with the opening of the chest;
without opening the chest.

open heart surgery

Chest opening operations

Such surgical intervention is used in especially severe cases, when full accessibility of the heart is required during the operation.

Opening of the chest is performed with such pathologies:

tetralogy of Fallot (the so-called congenital heart disease with four serious violations of the anatomical structure);
serious anomalies of intracardiac partitions, valves, aorta and coronary arteries;
heart tumors.

The patient arrives at the hospital one day before the operation. Passes inspection, gives written consent. Be sure to wash with antibacterial soap and shave your hair. Where do you shave your body hair? The hair will be shaved at the site of the proposed incision. If you are going to have a coronary bypass surgery, you will have to shave your legs and groin. In the case of a heart valve replacement, it is necessary to shave the hair in the lower abdomen and in the groin area.

The surgery is performed under general anesthesia. To gain access to the heart, the surgeon opens the chest of the person being operated on. The patient is connected to an artificial lung ventilation apparatus, the heart stops for a while and surgical manipulations are performed with the organ.

How long the operation takes depends on the severity of the pathology. On average, several hours.

Tetralogy of Fallot

Open heart surgery has two advantages.

The surgeon has full access to the patient's heart.
Such a surgical intervention is possible without state-of-the-art medical equipment.

However, there are also significant drawbacks.

Surgical manipulations with the heart last several hours, which leads to fatigue of the operating team, during the operation there is a higher probability of making an erroneous action.
Opening the chest is fraught with various injuries.
There is a noticeable scar after heart surgery.
Various complications are not excluded:

myocardial infarction,
thromboembolism,
bleeding,
infections;
coma after surgery.

A long recovery is required with significant limitations in the patient's activities.

In most cases, when surgery is performed with an opening of the chest, disability is given after heart surgery, as after a heart attack.

What operations and under what pathologies are performed on the open heart?

Pathologies of the coronary arteries

Coronary artery bypass grafting is done in case of serious atherosclerotic lesions of the coronary arteries, which led to a severe form of coronary heart disease. The essence of shunting is to create a bypass for blood flow to the heart using a shunt, for which an artery or vein taken from the patient is used. For example: mammary coronary artery bypass grafting (MCB) is performed using the internal mammary (mammary) artery.

Operation Ross

Heart valve defects

Today, valves made from the patient's biological material are used to replace damaged valves.

The Ross procedure involves using the patient's own valvular pulmonary artery to replace a diseased aortic valve. An implant is placed in place of the pulmonary valve. Eliminates complications associated with rejection of a valve made of foreign material. Made for both adults and children.
The Ozaki operation involves the use of the patient's own tissue. Only in this case, the replacement of the aortic valve is performed with a valve made from the patient's pericardium. Complications with valve rejection are not observed for the same reason.

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.
