Open heart surgery. Features of cardiac surgery. The operation of stenting of the vessels of the heart: indications and features of the conduct

Heart surgery is performed only when other methods of therapy cannot help the patient's condition. Heart surgery can prevent death in a patient, but the risk of an adverse outcome remains quite high.

Despite the fact that cardiac surgery does not stand still and develops, heart surgery is very difficult to perform. The best specialists in cardiac surgery are engaged in it. But even this important fact cannot shield the operated person from complex consequences.

Complications in the postoperative period can even lead to death.

Indications for surgery

As mentioned earlier, cardiac surgery is used in cases where there are no other options to save the patient's life. Heart surgery requires a very serious approach.

Heart transplantation is considered the most complex and serious surgical intervention. The operation is carried out under the strict supervision of highly qualified specialists.

Indications for heart surgery of any complexity are as follows:

• transient development of ailments of the cardiovascular system;
• in the absence of results with drug treatment;
• late referral to a medical facility.

Heart surgery helps to improve the general condition of the patient and eliminate the symptoms of a tormenting disease.

Cardiac cavity surgery is performed only after a complete diagnostic study and an accurate diagnosis by a cardio specialist.

Methods of surgical interventions

What are heart surgeries?

This is a pretty important question if you are going to have this major surgery. You will also need to know how the operation goes and how it is done.

This is necessary in order to make, perhaps, the main decision in your life, on which all future fate will depend.

Closed Interventions

This is a heart operation that does not affect the organ itself. It is done without touching the heart. For its implementation, there is no need for special equipment, except for such as the instruments of the surgeon.

The heart cavity does not "open". That is why it is called "closed".

Such an intervention is performed at the initial stage of the development of the disease, when the patient's condition can only be improved by operations.

Open Interventions

There is also open surgery. This type of operation requires the opening of the heart cavities in order to eradicate the existing pathology.

Open heart surgery is performed using a special device - heart-lung machine or heart-lung machine.

With an open intervention, the cavities are open, the heart and pulmonary organs are disconnected from blood circulation. This makes it possible to intervene on a "dry" organ.

All blood through the vein goes to specialized surgical equipment. There they pass through artificial lungs, enriched with oxygen and release carbon dioxide, transforming from the blood of a vein into an arterial one. Then it is driven by a special pump into the aorta of the operated person, in other words, into the systemic circulation.

Innovative techniques help to create all the "insides" of the equipment (also an artificial lung), with which the patient's blood comes into contact, "disposable", that is, once for one person. This will reduce the possible disastrous consequences.

Today, the heart-lung machine helps to stop the functioning of the heart organ and lungs for several hours. Thereby allowing to carry out the hardest operations of open character.

X-ray surgical interventions

This type of intervention began to be used quite recently. But thanks to innovative equipment, they occupy an important place in heart surgery.

With the help of a special catheter, surgical instruments are inserted into a strip section of the cardiac organ, or into the opening of the vessel. Further, with the help of the pressure that the device creates, the valves of the abdominal incisions are opened. They amplify or distort the partitions, or vice versa, using the device, the distortion is eliminated.

Special tubes are introduced into the lumen of the necessary vessel, thereby helping to slightly open it.

The process during such operations is carefully monitored by a special computer and control is made over each action. Thanks to this, operations are performed with less risk of injury and with a greater likelihood of a favorable outcome.

If you have had an X-ray surgery, the effectiveness of it is higher.

Action plan before surgery

Before surgery on the cardiac organ, preparation is necessary. If you have enough time, at least a few days or weeks, you need to take care of your body. Eat healthy, nutrient-rich foods.

Get plenty of rest, walk in the fresh air, do physical exercises that the treating specialist recommended to you.

Proper nutrition

Try to eat only natural foods every day and more than once, even if you have no appetite. Your body needs to consume plenty of proteins, vitamins and minerals.

Thanks to a healthy diet, the surgical intervention itself and the rehabilitation period are more favorable.

Relaxation

Do not force your body to overwork before surgery. The more you rest, the stronger and stronger your body will become.

If you want to visit relatives or invite you to visit, say that you need to gain strength before a difficult process. Relatives will always understand you and will not be offended.

Nicotine use

It's no secret for everyone that smoking affects negatively even the body of a completely healthy person. What can we say about patients with cardiac pathology.

Nicotine affects the heart in the following negative way: it develops arteriosclerosis, increases pressure in the blood vessels, and makes the heart vessels tighten. It also narrows blood-forming arteries and increases the concentration of mucous fluid in the pulmonary organs.

This leads to more difficult adaptation after surgery.

rehabilitation period

After a surgical intervention on the cardiac organ, if an insufficient amount of time has passed, it is even forbidden to get out of the ward bed. The entire rehabilitation period, the patient is in the intensive care unit.

This department is intended for patients who have a risk of death.

A special dietary diet plays a huge role in rehabilitation. His attending specialist appoints individually for each patient. You can start eating only with lean gruels and vegetable broths, but after a few days the diet increases significantly.

After the patient is transferred to a regular ward, as a rule, the attending physician will allow the use of the following products:

• cereals from coarse grinding (barley, barley groats, unpolished rice). You can also include oatmeal in the diet 2-3 times a week;
• dairy production: fat-free curd mass, cheese with a fat content of not more than 20%;
• vegetables and fruits: fresh, steamed and in various salads;
• small pieces of boiled chicken, turkey and rabbit. As well as homemade steamed cutlets;
• various varieties of fish: herring, salmon, capelin, etc.;
• all soups without fried ingredients and without fat content.

Under no circumstances should the following foods be consumed.

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.

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

1. 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.
2. 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.
3. 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.
4. Installing a pacemaker. Cardiac arrhythmias, severe bradycardia may be indications for installation, which, thanks to modern technology, can also be performed endoscopically.

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?

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

By urgency, cardiosurgical operations are emergency and planned.

1. 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.
2. 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.

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

However, there are also significant drawbacks.

1. 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.
2. Opening the chest is fraught with various injuries.
3. There is a noticeable scar after heart surgery.
4. Various complications are not excluded:

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

1. 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.

1. 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.
2. 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.
