Operations on the heart and blood vessels: types, features. Heart surgery Do fat people do heart surgery
Heart surgeries are very common these days. Modern cardiac surgery and vascular surgery are very advanced. Surgical intervention is prescribed in the case when conservative drug treatment does not help, and, accordingly, the normalization of the patient's condition is impossible without surgery.
For example, heart disease can only be cured by surgery, this is necessary in the case when blood circulation is severely disturbed due to pathology.
And as a result, a person feels bad and severe complications begin to develop. These complications can lead not only to disability, but also to death.
Often prescribed surgical treatment of coronary heart disease. Since it can lead to myocardial infarction. Due to a heart attack, the walls of the cavities of the heart or aorta become thinner and protrusion appears. This pathology can also be cured only by surgery. Quite often, operations are performed due to disturbed heart rhythm (RFA).
They also perform heart transplantation, that is, a transplant. This is necessary when there is a complex of pathologies due to which the myocardium is not able to function. Today, such an operation prolongs the life of the patient by an average of 5 years. After such an operation, the patient is put on disability.
Operations can be carried out urgently, urgently, or a planned intervention is prescribed. It depends on the severity of the patient's condition. An emergency operation is performed immediately, immediately after the diagnosis is established. If such an intervention is not carried out, then the death of the patient may occur.
Such operations are often performed on newborns immediately after birth with congenital heart disease. In this case, even minutes are important.
Urgent operations do not require fast execution. In this case, the patient is prepared for some time. As a rule, it is several days.
A planned operation is prescribed if at this time there is no danger to life, but it must be carried out to prevent complications. Doctors prescribe surgery on the myocardium only if it is necessary.
Invasive Research
Invasive methods for examining the heart are to conduct catheterization. That is, the study is carried out through a catheter, which can be installed both in the cavity of the heart and in the vessel. With the help of these studies, you can determine some indicators of the work of the heart.
For example, blood pressure in any part of the myocardium, as well as determine how much oxygen is in the blood, evaluate cardiac output, vascular resistance.
Invasive methods allow you to study the pathology of the valves, their size and degree of damage. This study takes place without opening the chest. Cardiac catheterization allows you to take an intracardiac electrocardiogram and phonocardiogram. This method is also used to monitor the effectiveness of drug therapy.
Such studies include:
With selective coronary angiography, contrast is injected into one of the coronary arteries (right or left).
Coronary angiography is often performed in patients with angina pectoris 3-4 functional class. In this case, it is resistant to drug therapy. Doctors need to decide what type of surgical treatment is needed. It is also important to carry out this procedure for unstable angina.
Also, invasive procedures include punctures and probing of the heart cavities. With the help of probing, it is possible to diagnose heart defects and pathologies in the LV, for example, it can be tumors, or thrombosis. To do this, use the femoral vein (right), a needle is inserted into it through which the conductor passes. The needle diameter becomes about 2 mm.
When performing invasive studies, local anesthesia is used. The incision is small, about 1-2 cm. This is necessary to expose the desired vein for the installation of the catheter.
These studies are carried out in different clinics and their cost is quite high.
Surgery for heart disease
Heart defects include
- stenosis of the heart valves;
- insufficiency of heart valves;
- septal defects (interventricular, interatrial).
valve stenosis
These pathologies lead to many disorders in the work of the heart, that is, the goals of operations for defects are to relieve the load from the heart muscle, restore the normal functioning of the ventricle, as well as restore contractile function and reduce pressure in the heart cavities.
To eliminate these defects, the following surgical interventions are performed:
Often, after heart disease surgery, a person is given a disability.
Operations on the aorta
Open surgeries include:
- Prosthetics of the ascending aorta. At the same time, a valve-containing conduit is installed; this prosthesis has a mechanical aortic valve.
- Prosthetics of the ascending aorta, while the aortic valve is not implanted.
- Prosthetics of the ascending artery and its arch.
- Surgery to implant a stent graft in the ascending aorta. This is an endovascular intervention.
Prosthetics of the ascending aorta is the replacement of this section of the artery. This is necessary in order to prevent serious consequences, for example, a break. To do this, prosthetics are used by opening the chest, and endovascular or intravascular interventions are also performed. In this case, a special stent is installed in the affected area.
Of course, open-heart surgery is more effective, since in addition to the main pathology - aortic aneurysm, it is possible to correct the concomitant one, for example, stenosis or valve insufficiency, etc. And the endovascular procedure gives a temporary effect.
When prosthetics of the aortic arch are used:
- Open distal anastomosis. This is when the prosthesis is installed, so that it does not affect its branches;
- Arc semi-replacement. This operation consists in replacing the artery where the ascending aorta passes into the arch and, if required, replacing the concave surface of the arch;
- Subtotal prosthetics. This is when the replacement of branches (1 or 2) is required during prosthetics of the arterial arch;
- Complete prosthetics. In this case, the arch is prosthetized together with all supra-aortic vessels. This is a complex intervention that can cause neurological complications. After such an intervention, a person is given a disability.
Coronary artery bypass grafting (ACS)
CABG is open-heart surgery that uses a patient's vessel as a shunt. This heart operation is needed in order to create a bypass for the blood, which will not affect the occlusive section of the coronary artery.
That is, this shunt is installed on the aorta and brought to the area of the coronary artery not affected by atherosclerosis.
This method is quite effective in the treatment of coronary heart disease. Due to the installed shunt, the blood flow to the heart increases, which means that ischemia and angina pectoris do not appear.
CABG is prescribed if there is angina pectoris, in which even the smallest loads cause seizures. Also, indications for CABG are lesions of all coronary arteries, and if an aneurysm of the heart has formed.
During CABG, the patient is put into general anesthesia, and then, after opening the chest, all manipulations are performed. This operation can be performed with or without cardiac arrest. And also, depending on the severity of the pathology, the doctor decides whether it is necessary to connect the patient to a heart-lung machine. The duration of CABG can be 3-6 hours, it all depends on the number of shunts, that is, on the number of anastomoses.
As a rule, the role of the shunt is performed by a vein from the lower limb, and sometimes a part of the internal thoracic vein, the radial artery, is also used.
Today, CABG is performed, which is performed with minimal access to the heart, while the heart continues to work. Such an intervention is considered not as traumatic as the others. In this case, the chest is not opened, the incision is made between the ribs and a special expander is also used so as not to affect the bones. This type of CABG lasts 1 to 2 hours.
The operation is performed by 2 surgeons, while one makes an incision and opens the sternum, the other operates on the limb to take a vein.
After carrying out all the necessary manipulations, the doctor installs drains and closes the chest.
CABG significantly reduces the likelihood of a heart attack. Angina pectoris does not appear after surgery, which means that the quality and duration of the patient's life increase.
Radiofrequency ablation (RFA)
RFA is a procedure that is performed under local anesthesia, since the basis is catheterization. Such a procedure is carried out in order to exfoliate the cells that cause arrhythmia, that is, the focus. This happens through a catheter-conductor, which conducts an electric current. As a result, tissue formations are removed by RFA.
After conducting an electrophysical study, the doctor determines where the source is located, which causes a rapid heartbeat. These sources can be formed along the conducting paths, as a result of which an anomaly of the rhythm manifests itself. It is RFA that neutralizes this anomaly.
RFA is carried out in case of:
- when drug therapy does not affect the arrhythmia, and also if such therapy causes side effects.
- If the patient has Wolff-Parkinson-White syndrome. This pathology is perfectly neutralized by RFA.
- If a complication may occur, such as cardiac arrest.
It should be noted that RFA is well tolerated by patients, since there are no large incisions and opening of the sternum.
The catheter is inserted through a puncture in the thigh. Only the area through which the catheter is inserted is anesthetized.
The guide catheter reaches the myocardium, and then a contrast agent is injected. With the help of contrast, the affected areas become visible, and the doctor directs the electrode to them. After the electrode acted on the source, the tissues are scarred, which means that they will not be able to conduct the impulse. After RFA, a bandage is not needed.
Carotid surgery
There are such types of operations on the carotid artery:
- Prosthetics (used with a large lesion);
- Stenting is performed if stenosis is diagnosed. In this case, the lumen is increased by installing a stent;
- Eversion endarterectomy - at the same time, atherosclerotic plaques are removed along with the inner lining of the carotid artery;
- Carotid endarectomy.
These operations are performed under both general and local anesthesia. More often under general anesthesia, as the procedure is performed in the neck and there are discomfort.
The carotid artery is occluded, and in order to continue the blood supply, shunts are installed, which are bypass routes.
Classical endarterectomy is done if long plaque lesions are diagnosed. During this operation, the plaque is peeled off and removed. Next, the vessel is washed. Sometimes it is still necessary to fix the inner shell, this is done with special seams. At the end, the artery is sutured with a special synthetic medical material.
Endarterectomy of the carotid arteries
Eversion endartectomy is performed in such a way that the inner layer of the carotid artery at the site of the plaque is removed. And after that they fix, that is, sew. For this operation, the plaque should be no more than 2.5 cm.
Stenting is performed using a balloon catheter. This is a minimally invasive procedure. When the catheter is located at the site of stenosis, it inflates and thereby expands the lumen.
Rehabilitation
The period after heart surgery is no less important than the operation itself. At this time, the patient's condition is monitored by doctors, and in some cases, cardio training, therapeutic diets, etc. are prescribed.
Other recovery measures are also needed, such as wearing a bandage. The bandage at the same time fixes the seam after the operation, and of course the entire chest, which is very important. Such a bandage should be worn only if the operation is performed on the open heart. The cost of these items may vary.
The bandage that is worn after heart surgery looks like a T-shirt with tightness clamps. You can purchase male and female versions of this bandage. The bandage is important to prevent lung congestion by coughing regularly.
Such prevention of stagnation is quite dangerous because the seams can disperse, the bandage in this case will protect the seams and contribute to strong scarring.
Also, the bandage will help prevent swelling and bruising, promotes the correct location of organs after heart surgery. And the bandage helps to relieve the load from the organs.
After heart surgery, the patient needs rehabilitation. How long it will last depends on the severity of the lesion and the severity of the operation. For example, after CABG, immediately after heart surgery, you need to start rehabilitation, this is a simple exercise therapy and massage.
After all types of heart surgery, medical rehabilitation, that is, supportive therapy, is needed. In almost all situations, the use of antiplatelet agents is mandatory.
If there is high blood pressure, then ACE inhibitors and beta-blockers are prescribed, as well as drugs to lower blood cholesterol (statins). Sometimes the patient is prescribed physical procedures.
Disability
It should be noted that disability is given to people with diseases of the cardiovascular system even before surgery. There must be evidence for this. From medical practice, it can be noted that they necessarily give disability after coronary artery bypass grafting. Moreover, there may be a disability of both 1 and 3 groups. It all depends on the severity of the pathology.
People who have circulatory disorders, grade 3 coronary insufficiency, or have had a myocardial infarction are also entitled to disability.
Regardless of whether the operation was performed or not yet. Patients with grade 3 heart defects and combined defects can apply for disability if there are persistent circulatory disorders.

How are operations performed?
An operation is an intervention in the human body with a violation of its integrity. Each disease requires an individual approach, which naturally affects the way the operation is performed.
How heart surgery is done: preparation for surgery
Heart surgery (cardiac surgery) is one of the most difficult to perform, dangerous and responsible type of surgical intervention.
Planned operations are usually carried out in the morning. Therefore, the patient is not allowed to eat or drink in the evening (for 8-10 hours), and immediately before the operation, a cleansing enema is given. This is necessary in order for the anesthesia to work as it should.
The place where operations are performed must be sterile. In medical institutions, special rooms are used for these purposes - operating rooms, which are regularly sterilized by quartz treatment and special antiseptics. In addition, all medical personnel who take part in the operation wash themselves before the procedure (you even have to rinse your mouth with an antiseptic solution), and also change into special sterile clothes, put on sterile gloves on your hands.
The patient is also put on shoe covers, a cap on his head, and the operation field is treated with an antiseptic. If necessary, before the operation, the patient's hair is shaved if the surgical field is covered with it. All these manipulations are necessary to avoid infection of the surgical wound with bacteria or other dangerous active microorganisms.
Narcosis or anesthesia
Anesthesia is a general anesthesia of the body with its immersion in drug-induced sleep. 
During surgical interventions on the heart, general anesthesia is used, and in some cases, during endovideosurgical operations, spinal anesthesia, in which a puncture is made into the spinal cord at the level of the lower back. Substances that cause pain relief can be administered in various ways - intravenously, through the respiratory tract (inhalation anesthesia), intramuscularly or in combination.
Course of open heart surgery
After the person goes into medical sleep and ceases to feel pain, the operation itself begins. The surgeon uses a scalpel to open the skin and soft tissues on the chest. Cardiac surgery may also require an “opening” of the chest. To do this, with the help of special surgical instruments, the ribs are sawn. Thus, doctors “get” to the operated organ and put special dilators on the wound, which provide better access to the heart. Junior medical staff, using suction, removes blood from the surgical field, and also cauterizes cut capillaries and blood vessels so that they do not bleed. 
If necessary, the patient is connected to an artificial heart machine, which will temporarily pump blood through the body, while the operated organ is artificially suspended. Depending on what kind of heart surgery is performed (what kind of damage is eliminated), appropriate manipulations are carried out: it can be the replacement of blocked coronary arteries, the replacement of heart valves in case of defects, vein bypass surgery or the replacement of an entire organ.
Extreme care is required from the surgeon and all staff, as the life of the patient depends on it. It should also be added that during the operation, blood pressure and some other indicators are constantly monitored, which indicate the patient's condition.
Endovideosurgery: stenosis and angioplasty
Today, more and more often, heart surgery is performed not by an open method - with a chest incision, but with access through the femoral artery on the leg, under the control of an X-ray machine and a microscopic video camera. After preparing for 
operation, which is similar for all types of surgical interventions, and putting the patient into a medical sleep, access to the femoral artery is opened through an incision in the leg. A catheter and a probe with a video camera at the end are inserted into it, thanks to which access to the heart is provided.
In this way, angioplasty with stenosis of blood vessels is carried out in cardiac surgery, which is necessary for blockage of the coronary vessels that feed the heart itself with blood. Special stands are installed in the narrowed vessels - cylindrical implants that do not allow the arteries to clog anymore, which prevents the possibility of developing coronary disease.
After the main part of the operation is over and the heart is on its own again 
functions, stitching of damaged nerves, vessels and tissues is performed. The wound is again treated with an antiseptic, the surgical field is closed, soft tissues and skin are sutured with special threads. A medical bandage is applied to the external wound. After the end of all these procedures, the patient is taken out of anesthesia.
Other types of transactions
In addition to the abdominal operations described above, there are also operations performed in a less traumatic way:
- Laparoscopy - is performed using a laparoscope, which is inserted through 1-2 cm incisions in the skin. Most often used in gynecology, gastrectomy and other operations in the abdominal cavity. You can read more about this
- Laser surgery - is carried out using a special laser beam. Usually, operations are performed in this way on the eyes, when removing skin formations, etc. You can read more about the method
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.
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.

Such surgical manipulations are within the competence of cardiac surgeons, and are one of the most complex in nature. Heart surgery is a last resort in the treatment of serious cardiovascular diseases, which are resorted to in order to improve the quality of life of the patient, and sometimes even save his life.
In Russia, this type of surgical intervention is not practiced as often as, for example, in America or in European countries. First of all, this is due to the cost of such treatment: not every citizen of the Russian Federation is able to pay the costs of the operation out of his own pocket.
At the same time, this branch of medicine in domestic medical institutions is constantly developing, which makes it possible for patients to receive qualified advice and assistance when applying.
When is heart surgery performed - indications and timing
The main pathologies that may require surgical intervention are:
- Poor myocardial blood supply. A similar condition in medical circles is called coronary heart disease. IHD can lead to the formation of an aneurysm, extensive thrombosis. With all the described ailments, certain surgical procedures on the heart may be required.
- Heart defects that have both innate and acquired nature. Many defects in the structure of the heart valve are incompatible with life. Therefore, such pathologies are diagnosed even in the prenatal period, and the operation itself is carried out in the first days of the baby's life.
- Failures in the frequency, sequence and rhythm of heart contraction, - arrhythmias.
Common indications for heart surgery are the following pathological conditions:
- Active deterioration of vital signs against the background of the development of underlying heart disease.
- The inability of drug therapy to cope with the manifestations of the disease.
- Noticeable deterioration in the functioning of the heart muscle that cannot be eliminated with medications.
- advanced stage of the disease. This happens when the patient does not seek qualified help in time.
It should also be taken into account that any surgical manipulations on the heart carry a risk and are fraught with the development of a number of exacerbations in the rehabilitation period. Doctors turn to such treatment when other measures do not bring the desired effect.
In addition, heart surgery requires a comprehensive examination of the patient and careful preparation for the operation. This will ensure a successful recovery and minimize the likelihood of postoperative complications.
Based on the patient's condition, the type of surgical intervention under consideration is:
- emergency. In such a situation, examination and preparation are carried out in a minimal amount, and the operation itself is carried out as soon as possible. This type of manipulation is prescribed for life-threatening conditions, when every minute counts: with aneurysm rupture, extensive myocardial infarction. Often, emergency interventions on the heart are performed on newborns with complex heart disease.
- Urgent. There is time for diagnostic and preparatory measures, but not much. After receiving the results of the examination, surgical treatment of the heart disease is carried out.
- planned. In some medical sources, this type of operation is called elective. After a detailed study of the patient's condition by a cardiac surgeon, a final decision is made on the need for surgical intervention. Together with the patient or his parents (when operating on a child), the exact date of the operation is agreed.
Closed and open heart surgeries - how they are performed and to whom they are prescribed
Based on the type of defect that needs to be eliminated, various methods of surgical intervention are used:
Note!
Not so long ago, a new direction in the treatment of heart defects began to be applied in cardiac surgery - X-ray surgery. In essence, they are minimally invasive - the doctor makes small incisions or punctures, and brings special instruments to the heart zone through the catheter. An access point can be, incl. and femoral vessels. Using cans, you can increase the diameter of the narrowed valve - or reduce it by opening the patch (its design is similar to an umbrella). With the help of expanding tubules, vascular stenosis is eliminated.
The progress of the entire procedure is monitored through the monitor screen - this ensures the effectiveness of the operation, as well as its safety for the patient. In addition, during the manipulation under consideration, general anesthesia is not used: the doctor is limited to anesthesia with mini-accesses.
X-ray surgery can be both the main and auxiliary methods of treating errors in the work of the heart.
Most popular types of heart surgery
To date, the following operations are used in cardiac surgery practice:
1. With coronary heart disease:
2. In case of diagnosing heart disease:
3. In the presence of arrhythmia:
In cases where the treatment of individual anatomical structures of the heart is impossible or ineffective, and the main organ for pumping blood cannot cope with its main function, they perform heart transplant .
This operation is fraught with a number of complications, among which is graft rejection.
Today, scientists are conducting research to maximize the life extension of those who have survived heart transplants.
