How is heart surgery done? Types of heart operations - indications for performance. Aortic heart disease

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 disc
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.

Rostislav Zhadeiko, especially for the project .

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:

1. Rapid deterioration of the patient's condition and progression of the underlying disease of the heart or blood vessels.
2. 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.
3. The presence of acute signs of deterioration of the underlying myocardial disease, which cannot be eliminated by conventional analgesics or antispasmodics.
4. 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:

1. 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.
2. Biological implants are made from animal tissues. 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:

1. IHD (ischemic heart disease), which leads to impaired blood circulation and oxygen starvation of the myocardium.
2. Myocardial infarction.
3. 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.

Tuesday is surgery day. The team is preparing for a long morning work. During the operation, the chest is opened and the heart is prepared for vessel transplantation.

Disease history

Mr. Thomas, a 59-year-old tanker driver, is married with two adult children. He had shingles on the right side of his neck, followed by an uncomfortable constriction in his throat, accompanied by sweating and nausea. He first felt these symptoms while walking up the steps of his truck. They continued, and Thomas decided to seek the advice of a therapist.

Thomas's high blood pressure, obesity, and long history of smoking were reason enough for an ECG. Her results showed the presence of coronary heart disease. Thomas was referred to a cardiac expert (a cardiac internist, not a surgeon). Despite the applied medical treatment, the pain continued.

Tests confirmed the presence of the disease, in particular an angiogram (a test using a dye injected into the artery to detect narrowing) revealed a narrowing in the left main coronary artery with damage to the left and right vessels. Since medical treatment was unsuccessful and angioplasty (stretching a narrowed vessel using a catheter) was not an option, Mr. Thomas was referred for surgery.

Monday

Mr. Thomas is hospitalized. His anamnesis, data of examinations and tests were analyzed. Two units of blood for transfusion are tested for compatibility. The patient is explained the essence of the operation and warned about the risk associated with it. Obtain written consent for CABG.

Tuesday

Early in the morning, Mr. Thomas is being prepared for the operation.

7:05 Premedication and anesthesia

8:15 a.m. Mr. Thomas was sedated 70 minutes ago and a ventilation tube has already been placed in his airway. After the application of anesthesia and paralyzing agents, his breathing is supported by a ventilator. Prior to transferring Mr. Thomas to the operating room, the anesthesiologist establishes monitoring of venous and arterial blood flow.

8:16 OR Mr. Thomas is set up. On the left - a table with instruments, on the right - a ready-to-use heart-lung apparatus.

8:25 Patient in the operating room. The skin of his chest and legs are treated with an antiseptic solution to reduce the risk of infection.

8:40 Opening of the chest

The skin has already been processed, the patient is dressed in sterile clothes. One of the surgeons makes an incision in the leg to extract the vein, and the second cuts the skin on the chest. After a preliminary incision with an ordinary scalpel, he uses an electric one, which cuts the vessels, stopping the bleeding.

8:48 The surgeon cuts the sternum bone with an electric saw with a pneumatic drive.

8:55 Artery and vein removal

View of the internal thoracic (mammary) artery in the mirror in the center of the surgical lamp. This artery is very elastic. The top end of it will remain in place, it will be cut off at the bottom and then connected to the coronary artery.

An angled retractor is placed along the left edge of the sternum to lift it and expose the mammary artery that runs along the inside of the chest.

At the same time, one of the main veins on the leg - the great saphenous vein - is prepared for transplantation. It is almost completely removed from the left thigh.

9:05 Connecting to the heart-lung machine

The heart-lung machine is not yet connected to the patient. One of the five rotating pumps circulates the blood, while the rest are used as side pumps to transport separated blood to prevent blood loss during surgery. The patient needs to enter heparin - a means to thin the blood and prevent the formation of clots during its passage through plastic tubes.

Tubes to the heart-lung apparatus. On the left, with bright red blood, is the arterial return line, which carries blood back into the patient's aorta. On the right - two tubes that drain blood from the inferior and superior vena cava under the influence of gravity. The incision in the sternum is fixed with a spacer.

Part of the heart-lung apparatus is a membrane oxygenating device that maintains blood circulation in the patient's body. At the moment, the device is filled with blood, carbon dioxide is removed from it. The blood is re-oxygenated and returned to the patient's body.

An arterial return tube is inserted into the aorta (the main artery of the body) and two venous drains are inserted into the vena cava (the main vein of the body).

9:25 Cardiac arrest

On the main artery - the aorta - a clamp is placed to isolate the heart from artificial blood circulation. Chilled fluid is injected into the isolated aorta to stop the heart. The surgeon puts on special glasses for microsurgery with loupes that give a magnification of 2.5 times. The blood vessels he will transplant are 2-3 mm in diameter, and the sutures are the diameter of a human hair.

A thorough examination of the heart is carried out to confirm the data obtained using the angiogram. It is specified which coronary arteries need to be bypassed. It was decided to make two shunts.

After stopping the blood flow in the left anterior descending artery, a 1 cm long incision is made at the bypass site using a surgical loop.

10:00 First bypass

Close-up of the heart. The left internal mammary (mammary) artery - in the upper left corner - is sutured to the left anterior descending artery so that blood flow to the heart is restored. Arteries are hidden by epicardial fat.

The end of the left internal mammary artery is sutured laterally to the left anterior descending artery. This forms the first bypass shunt.

The position of the first performed shunt. The end of the lower part of the left internal mammary artery - a blood vessel with a diameter of 3 mm - is completely sutured to the left anterior descending artery.

10:22 Second bypass

The second bypass shunt is sutured with the upper end to the aorta, and with the lower end to the right posterior descending artery. The transverse clamp is removed, blood flow through the heart is restored.

The upper end of the venous shunt is connected to the aorta. Part of the aorta is isolated with an arcuate clamp and a hole is made into which a vein is sutured.

End of both bypass processes. The second shunt, shown on the left side of the diagram, is formed from the saphenous vein of the leg.

11:18 Chest closure

Circulation is restored, the heart contracts after an electric shock with the transition from ventricular fibrillation to sinus mode. Two drains are installed in the anterior and posterior parts of the heart. The blood thinning effect of heparin was eliminated by the drug protamine. The surgeon sews the separated halves of the sternum together. The skin will be closed with an internal absorbable suture.

The nurse applies tape to the suture and to the drainage tubes leading from the patient's chest. Soon the patient will be placed in the intensive care unit, where he will be observed.

The human body. Outside and inside. №1 2008

The operation on the heart, which at one time was compared with the first manned flight into space, is exactly 50 years old. It is very pleasant that our surgeon Vasily Kolesov conceived and executed it. Now it is one of the most common procedures in the world to prevent a heart attack and bears the name of its developer.

"The Soviet surgeon dared to raise his hand on his heart" - in 1964 this news outraged the entire world medical community. No one believed that coronary heart disease could be treated with surgery. Numerous experiments on animals ended unsuccessfully. But Vasily Ivanovich Kolesov, a professor at the Leningrad Medical University, proves that operating on a healthy heart in dogs and a diseased heart in humans is not the same thing, and he decides on a bold experiment.

Stanislav Pudyakov then assisted the surgeon. He recalls: a 44-year-old patient was tormented by severe pain in the region of the heart.

“His idea, if compared historically, is similar to the thoughts of Tsiolkovsky, who said that tomorrow we will be on the moon. They didn’t believe him until they really flew. And until Vasily Ivanovich did this first operation, no one believed in it” - says Stanislav Pudyakov.

The surgeon operated on a beating heart, which was also hard to believe. No one had done this before Kolesov, neither in our country nor in the world. Moreover, the doctor literally felt the sore spot with his hands. The equipment for diagnosing heart diseases simply did not exist then.

To restore the normal blood supply to the heart, Kolesov singled out the internal thoracic artery and sewed it to the coronary artery below the narrowing caused by the so-called atherosclerotic plaque. The blood flow went around, the patient was saved from a heart attack.

After the operation, people quickly returned to normal life and forgot about the pills forever. About operations that saved people from heart attacks and pains in the heart, they started talking abroad as a sensation. American magazines wrote about Kolesov: "Pioneer of coronary surgery."

“There were confessions among colleagues, among foreigners. A lot of Americans, Germans, French came, they looked at these operations with great curiosity and really wanted to continue what was started here,” says surgeon Alexander Nemkov.

Vasily Kolesov immediately warned: it would not be easy for young surgeons to repeat this. From now on, operations must be performed on a stopped heart. The advice was regarded as a guide to action. In 1967, American surgeons put them on stream.

The method of treatment of coronary heart disease, proposed by Vasily Ivanovich Kolesov, is considered the most effective after 50 years. Operations are performed by the best cardiac surgeons in clinics around the world. This is aerobatics, because, in fact, doctors must restart the main human organ.

“Speaking specifically about the operation of Vasily Ivanovich Kolesov, it is now being performed widely on a beating heart. What he did is incredible. The range of suture material that we use has changed, the needle holders that we use have changed incredibly. We use special magnifying lenses and we see this artery magnificently, which can be a millimeter, a millimeter and a half,” says surgeon Leo Bokeria.

Like half a century ago, coronary heart disease is the most common disease in the world. Now we can say with confidence that doctors have learned to deal with it. Thanks to the revolutionary method of Vasily Kolesov, even the most difficult patients can be saved.

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.
