Types of heart operations - indications for performance. open heart surgery lung heart surgery

Operations on the heart and blood vessels are performed by such a branch of medicine as cardiac surgery.

With the help of cardiac surgeons, many vascular and cardiac diseases can be effectively treated, thereby significantly prolonging the life of the patient.

Operations on the heart and blood vessels can significantly improve the general well-being of the patient.

They should be performed only after a thorough diagnosis and preparation of the patient.

It is very important to follow all the instructions of the specialist exactly.

Regardless of what kind of disease was detected in a person, there are the following general indications for operations on the heart and blood vessels:

Rapid deterioration of the patient's condition and progression of the underlying disease of the heart or blood vessels.
The lack of positive dynamics from the use of traditional drug therapy, that is, when taking pills no longer helps a person to maintain his condition in a normal way.
The presence of acute signs of deterioration of the underlying myocardial disease, which cannot be eliminated by conventional analgesics or antispasmodics.
The neglect of the underlying disease, in which the patient hesitated to contact the doctor, which led to very severe symptoms of the disease.

These procedures are indicated for patients with heart defects (regardless of whether they are congenital or acquired). Moreover, thanks to current techniques, this disease can be treated even in newborn babies, thereby providing them with a healthy life.

The next common indication is myocardial ischemia. In this case, surgery may be required when the underlying disease is aggravated by a heart attack. In this condition, the sooner surgery is performed, the greater the chance that the person will survive.

A significant indication for the need for surgical intervention can be acute heart failure, which provokes abnormal contraction of the myocardial ventricles. At the same time, it is important that the patient prepares for the operation in advance (to avoid postoperative complications in the form of a blood clot).

Often, surgery is required for myocardial valve disease, which was triggered by trauma or an inflammatory process. Rarely, other causes contribute to its appearance.

A serious reason for the urgent intervention of surgeons is the diagnosis of narrowing of the coronary valve of the artery, as well as endocarditis of infectious origin.

Additional conditions that may require a person to have myocardial surgery include:

Severe aortic aneurysm, which may result from trauma or be congenital.
Rupture of the ventricle of the heart, because of which the blood flow was disturbed.
Various types of arrhythmias that can be eliminated by inserting or replacing an already installed pacemaker. They are commonly used for atrial fibrillation and bradycardia.
Diagnosis of an obstruction in the myocardium in the form of tamponade, due to which the heart cannot pump the required volume of blood normally. This condition can occur under the influence of viral infections, acute tuberculosis and heart attack.
Acute insufficiency of the left ventricles of the myocardium.

Cardiac surgery is not always necessary for the above indications. Each case is individual and only the attending physician can decide what is best for a particular patient - traditional drug therapy or a planned (urgent) operation.

In addition, it should be noted that heart surgery may be required in case of exacerbation of the underlying disease, as well as if the first surgical intervention did not give the expected results. In this case, the patient may need to repeat manipulation. Its cost and preparation features (diet, medication) depend on the complexity of the operation.

Surgical interventions can be practiced both on the open myocardium and on the closed one, when the heart and its cavity are not completely affected. The first type of operations involves dissection of the chest and connecting the patient to artificial respiration equipment.

During open-type operations, surgeons artificially stop the heart for a while, so that within a few hours they can perform the necessary surgical procedures on the organ. These interventions are considered very dangerous and traumatic, but even very complex myocardial diseases can be eliminated with their help.

Closed type operations are more secure. They are usually used to correct minor heart and vascular defects.

There are the following most common types of myocardial operations, which are most often practiced in cardiac surgery:

Installation of artificial valves.
Operations according to the method of Glenn and Ross.
Coronary artery bypass grafting and stenting of arteries.
Ablation of radiofrequency type.

An operation called radiofrequency ablation is a low-traumatic procedure that allows you to achieve significant improvements in heart failure and various types of arrhythmias. It rarely causes side effects and is well tolerated by patients.

RA is performed using special catheters that are inserted under X-ray control. The patient is then given local anesthesia. During this operation, a catheter is inserted into the organ and, thanks to electrical impulses, the normal heart rhythm is restored to the person.

The next type of surgery is prosthetic heart valves. This intervention is very often practiced, since such a pathology as myocardial valve insufficiency is extremely common.

It should be noted that in the event of a severe failure in the patient's heart rhythm, he may need to install a special device - a pacemaker. It is needed to normalize the rhythm of the heart.

When prosthetic heart valves can be used the following types of implants:

Mechanical prostheses that are made of metal or plastic. They serve for a very long time (for several decades), however, they require a person to constantly take drugs to thin the blood, because due to the introduction of a foreign object in the body, a tendency to form blood clots actively develops.
Biological implants are made from animal tissue. They are very durable and do not require special preparations. Despite this, patients after a couple of decades often require a second operation.

Glenn and Ross operations are commonly used to treat children with congenital myocardial defects. The essence of these interventions is to create a special connection for the pulmonary artery. After this operation, the child can live for a long time, with little or no need for maintenance therapy.

During the Ross operation, the patient is replaced by a diseased myocardial valve with a healthy one, which will be removed from his own pulmonary valve.

Cardiac bypass surgery: indications and conduct

Coronary artery bypass grafting is a surgical intervention on the heart, during which an additional vessel is sewn in order to restore the disturbed blood supply in the clogged blood arteries.

Cardiac bypass surgery is practiced when the narrowed vessels of the patient are no longer amenable to drug treatment and the blood cannot circulate normally in the heart, causing ischemic attacks.

A direct indication for cardiac bypass surgery is acute coronary aortic stenosis. Most often, a neglected form of atherosclerosis leads to its development, which contributes to clogging of blood vessels with cholesterol plaques.

Due to vasoconstriction, blood cannot circulate normally and deliver oxygen to myocardial cells. This leads to its defeat and the risk of a heart attack.

Today, heart vessel bypass surgery can be performed both on a beating heart and on an artificially stopped one. At the same time, it should be noted that if shunting is done on a working myocardium, then the likelihood of postoperative complications is much higher than when performing a procedure on a stopped myocardium.

The course of this operation consists in blocking the main aorta and implanting artificial vessels into the affected coronary arteries. Usually, a vessel in the leg is used for shunting. It is used as a biological implant.

Contraindications to this surgical intervention may be an existing pacemaker or an artificial valve in the heart, the functions of which may be impaired during such an operation. In general, the need for shunting is determined individually by the doctor for each individual patient, based on the diagnostic data and the patient's symptoms.

After bypass surgery, the recovery period is usually fast, especially if the patient does not have any complications after the procedure. Within a week after the operation, the patient must comply with bed rest. Until the stitches are removed, a person needs to do wound dressings daily.

After ten days, a person can get out of bed and begin to perform simple movements of physiotherapy exercises in order to restore the body.

After the wound has completely healed, the patient is advised to go swimming and walk regularly in the fresh air.

It should be noted that the wound after shunting is not sewn with threads, but with special metal staples.. This is justified by the fact that the dissection falls on a large bone, so it needs to grow together as carefully as possible and ensure peace.

To make it easier for a person to move around after the operation, he is allowed to use special medical support bandages. They look like a corset and perfectly support the seams.

After surgery, due to blood loss, a person may experience anemia, which will be accompanied by weakness and dizziness. To eliminate this condition, the patient is advised to eat right and enrich his diet with beets, nuts, apples and other fruits.

To reduce the likelihood of re-constriction of blood vessels, alcohol, fatty and fried foods should be completely excluded from the menu.

The operation of stenting of the vessels of the heart: indications and features of the conduct

Arterial stenting is a low-traumatic angioplasty procedure, which involves the imposition of a stent into the lumen of the affected vessels.

The stent itself is similar to a conventional spring. It is injected into the vessel after it has been artificially dilated.

Indications for cardiac stenting surgery are:

IHD (ischemic heart disease), which leads to impaired blood circulation and oxygen starvation of the myocardium.
Myocardial infarction.
Clogging of blood vessels with cholesterol plaques, which lead to a narrowing of their lumen.

Additional contraindications to this procedure are the patient's individual intolerance to iodine, which is invariably used during stenting, as well as the case when the total size of the diseased artery is less than 2.5 mm (in this case, the surgeon simply cannot install the stent).

An operation is performed to stent the vessels of the heart by introducing a special balloon that will expand the lumen of the diseased vessel. Further, a filter is installed in this place, which prevents subsequent blood clots and stroke.

After that, a stent is inserted into the vessel; it will support the vessel from narrowing, serving as a certain frame.

The surgeon monitors the entire course of the operation through a monitor. At the same time, he will see the stent and the vessel well, since even at the beginning of the procedure, the patient is injected with an iodine solution, which will reflect all the actions of the surgeon.

The advantage of stenting is that this operation has a low risk of complications. Moreover, it is performed under local anesthesia and does not require a long period of hospitalization.

After stenting, the patient must remain in bed for a certain time (usually for a week). After that, if there are no complications, the person is allowed to go home.

It is very important to exercise regularly after this operation. At the same time, it is worth controlling your condition and not allowing physical overwork.

Every two weeks after the procedure, the patient must necessarily come to the doctor and undergo a follow-up examination. When pain occurs, a person should immediately report it to the doctor.

To recover faster, the patient should take all the drugs prescribed by the doctor. Sometimes drug therapy lasts a long time, more than one month in a row.

Be sure to follow a dietary diet after stenting.

It provides for the following:

Complete abstinence from alcohol and smoking.
Ban on all animal fats. Also, you can not eat caviar, chocolate, fatty meat and sweet confectionery.
The basis of the diet should be vegetable soups, fruit mousses, cereals and greens.
You need to eat at least six times a day, but at the same time, portions should not be large.
You should completely limit the consumption of salt and salted fish.
It is important to drink plenty of fluids to maintain normal water balance in the body. It is recommended to drink fruit compotes, juices and green tea. You can also use a rosehip decoction.

In addition, a person needs to control their blood pressure and blood sugar levels. This is especially important in the presence of already existing hypertension and diabetes, because these diseases can worsen the functioning of the heart.

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.

But now, the diagnosis has been made and the doctors understand what needs to be done next. I would like you to understand well by this moment, what will be discussed when they will explain everything in detail to you, what was found during the examination, what diagnosis was made, what needs to be done and when to choose the best way of treatment.

Here and now the main questions are being decided, and you must exactly imagine what you want to know before you make a decision on which a lot depends.

There are several options for conversation.

You will be offered operation, as the only way out, and doctors believe that it needs to be done urgently.
You are offered an operation, but they say that it can be postponed for a while.
You are denied an operation for a variety of reasons.

You need to understand what is being said and prepare for the conversation. Try to be calm and confident in yourself and in the doctors who want to help you. You must be together, on the same side, in the fight for the future of the child. Discuss everything, but your questions should be literate. Believe me, a lot depends on this too.

What do you need to know about in order to ask the right question? What are the operations? What should the child do? How will it all be? Who will do it? Let's talk about it calmly.

Today, all interventions, or operations, for congenital heart defects can be divided into three categories: "closed" operations, "open" and "X-ray surgery".

✔ Closed Operations These are surgical interventions in which the heart itself is not affected. They are performed outside of it, and therefore do not require the use of any special equipment other than conventional surgical instruments. The cavities of the heart are not “opened” with them, which is why they are called “closed”, and they are widely performed as the first stage of surgical intervention.

✔ Open Operations- These are surgical interventions in which it is necessary to open the cavities of the heart in order to eliminate the existing defect. For this, a special apparatus is used - a heart-lung machine (AIC), or "heart-lungs". For the period of the operation, both the heart and the lungs are switched off from the circulation, and the surgeon gets the opportunity to perform any operation on the so-called "dry", stopped heart.

All the patient's venous blood is sent to the apparatus, where, passing through an oxygenator (artificial lung), it is saturated with oxygen and gives off carbon dioxide, turning into arterial. Then the arterial blood is pumped into the patient's aorta by a pump, i.e. into the systemic circulation. Modern technologies allow all the internal parts of the device (including the oxygenator), with which the patient's blood comes into contact, to be made "disposable", i.e. use them only once and only for one patient. This dramatically reduces the number of possible complications.

Today, thanks to AIC, it is possible without much risk to turn off the heart and lungs from work for several hours (and the surgeon has the opportunity to operate on the most complex defects).

✔ X-ray surgery appeared relatively recently, but, thanks to the incredible progress of modern technologies, they have already taken their rightful place in the arsenal of cardiac surgery. More and more doctors are now using thin catheters, the ends of which are fitted with balloons, patches, or expandable tubes (folded like a folding umbrella). With the help of a catheter, these devices are carried into the cavity of the heart, or into the lumen of the vessel, and then, expanding the balloon, break the narrowed valve with pressure, increase or create a defect in the septum, or, conversely, by opening the patch umbrella, this defect is closed. The tubes are inserted into the lumen of the desired vessel and create a wider lumen. In adults, they even try to pass an artificial aortic valve through the catheter in this way, but so far these are only attempts. Doctors monitor the course of an X-ray surgical operation on the monitor screen and clearly control all manipulations with the probe, and therefore the advantage of such operations is not only less trauma, but also high safety and efficiency. X-ray surgery has not yet supplanted traditional surgical methods, but it is gaining more and more space both as an independent method and as an “auxiliary”, i.e. which can be applied not instead of, but together with the usual operation, sometimes simplifying and supplementing it in many ways.

Depending on the type of defect and the condition of the child, surgical operations can be emergency, urgent and elective, i.e. planned.

emergency heart surgery are the ones that should be done immediately after the diagnosis is made, because any delay threatens the life of the child. With congenital malformations, such situations are not uncommon, especially when it comes to newborns. Here the question of life is often decided by hours and minutes.

Emergency operations- those for whom there is no such insane urgency. The operation does not need to be done right now, but you can calmly wait a few days, prepare both you and the child, but it must be done urgently, because then it may be too late.

Planned, or elective, operation- this is an intervention made at the time chosen by you and the surgeons, when the child's condition does not inspire fear, but the operation, nevertheless, should not be postponed.

No cardiac surgeon will ever suggest surgery if it can be avoided. So, anyway, it should be.

Depending on the approach to surgical treatment, radical and palliative operations are distinguished.

✔ Radical heart surgery is a correction that completely eliminates the defect. It can be done with an open ductus arteriosus, septal defects, complete transposition of the main vessels, abnormal pulmonary vein drainage, atrioventricular communication, Fallot's tetrad and some other defects, in which the heart is fully formed, and the surgeon has the opportunity to completely separate the circulatory circles, while maintaining normal anatomical relationships. Those. the atria will connect to their ventricles through correctly positioned valves, and the corresponding great vessels will depart from the ventricles.

✔ Palliative heart surgery- auxiliary, “facilitating”, aimed at normalizing or improving blood circulation and preparing the vascular bed for radical correction. Palliative operations do not eliminate the disease itself, but significantly improve the child's condition. With some very complex defects, which until recently were generally inoperable, the child will have one, and sometimes two palliative operations, before the final radical stage becomes possible.

During a palliative operation, another "defect" is surgically created, which the child does not initially have, but due to which the circulatory pathways disturbed by the defect in the large and small circles are changed. These include surgical expansion of the atrial septal defect, all variants of intervascular anastomoses - i.e. additional shunts, messages between circles. The Fontan operation is the most “radical” of all such methods, after which a person lives without a right ventricle at all. With some of the most complex heart defects, it is impossible to correct the anatomically, and surgical treatment aimed at correcting blood flow can be called the “final” palliative correction, but by no means a radical operation.

In other words, with heart defects, when the intracardiac anatomy - the structure of the ventricles, the condition of the atrioventricular valves, the location of the aorta and the pulmonary trunk - are so changed that they do not allow for a real radical correction, today's surgery follows the path of eliminating poorly compatible with life of circulatory disorders, and then - long-term palliation. The first stage of this path is saving lives and preparing for further treatment, and protection from future complications, the second is the final stage of treatment. All together - this is a long way to the final operation, and on it one, two, and sometimes three steps must be overcome, but, ultimately, to make the child healthy enough for him to develop, learn, lead a normal life, which this long-term palliation will provide him. Check it out, not so long ago - 20-25 years ago it was simply impossible, and children born with the defects of this group were doomed to death.

Such a “final palliation” is the only way out in many cases; although it does not correct the defect itself, it provides the child with an almost normal life by improving the mixing of arterial and venous blood flows, the complete separation of circles, and the elimination of obstructions to blood flow.

Obviously, the very concept of radical and palliative treatment for some complex congenital heart defects is largely arbitrary, and the boundaries are erased.

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.
