Shunting
Bypass - creating an additional path to bypass the affected area of any vessel using a cavity plastic modeling operation. In simple words - creating a workaround for the flow of blood.
The operation is performed under general anesthesia. In general, a section of the subcutaneous vein of the thigh is chosen as the material for the shunt, since it has a sufficiently large diameter in the section, and the removal of its section almost does not affect the blood flow of the limb.
For 2019, coronary bypass surgery, as the "gold standard," is the most effective method of restoring blood flow in the coronary arteries of the heart.
Heart transplantation
2022: For the first time in Russia, a successful transplantation of the artificial left ventricle of the heart was carried out
For the first time in Russia, a successful transplantation of the artificial left ventricle of the heart was carried out. Such an operation was carried out by military cardiac surgeons from the A. A. Vishnevsky Central Military Clinical Hospital, the Ministry of Defense of the Russian Federation reported on September 22, 2022.
 | The first transplant of the "mechanical heart" - the artificial left ventricle - was performed by military cardiac surgeons in chronic heart failure in a patient with dilated cardiomyopathy, the agency said in a statement quoted by TASS. |  |
The transplant took place in a unique hybrid complex of a cardiac surgery center led by Doctor of Medical Sciences, Professor Alexander Lishchuk. It is noted that the Vishnevsky Military Hospital has created the only single operating complex in Russia with a resuscitation chamber, a blood harvesting station, a defibrillation system, breathing apparatus, the ability to make express histology and many other functions.
With its help, it was possible to transform the unified workspace of specialists in diagnostic procedures and cardiac surgery teams. Together with a team of cardiac surgeons, anesthesiologists, transfusiologists and engineers worked in the operating room to provide functional configuration of the system.
| | With this device, we unload the stretched left ventricle overloaded with volume, reduce the tension of its walls. Thus, we give him the opportunity to further restore his power of contraction and the function of the heart as a whole. With this course, it is possible to provide long-term mechanical support of the left ventricle with contraindications to further heart transplantation, - explained Alexander Lishchuk. | |
The operating complex allows you to simultaneously work with several areas of the human body and save time in helping a patient who has received multiple injuries, injuries, has a number of serious, serious diseases.[1]

For the first time in Russia, a pericardial prosthesis was created and used during heart surgery
For the first time in Russia, a prosthesis from pericardial tissues was created and used during heart surgery. This achievement was reported in September 2023 at the E. N. Meshalkin National Medical Research Center (NMIC).
For the first time in Russian practice, cardiac surgeons of the center designed a tubular prosthesis from the patient's own peri-cardiac tissues. A rare cardiovascular pathology was found in the patient. It consisted in the fact that not all pulmonary veins are associated with the heart, so part of the blood is discharged without entering the left atrium.
The arrangement of veins and vessels is similar to a curved saber because of this, a similar kind of heart defect is called "Turkish saber" syndrome. An insufficient amount of blood enters the heart, and one lung is smaller in size and because of this, the body has increased the network of vessels for feeding the lung.
It was necessary to build up the vessel, and the team made a non-standard decision - to use the tissues of the patient himself. The pericardium ("heart bag") of the patient was taken and a prosthetic vessel of a predetermined diameter was formed from it so that the inner lumen in the filled state was 15 mm.
| | We did not want to sew a conventional synthetic prosthetic vessel, as this dramatically increases the risk of thrombosis. Biological tissues are preferable, after all, the patient is a teenager, a young organism, - explains the cardiovascular surgeon of the Department of Congenital Heart Defects of the National Medical Research Center named after Meshalkina Timur Khapaev. | |
The entire operation, together with the manufacture of the prosthesis, took 2.5 hours and passed without complications. After 6 months, the control study confirmed the good work of the vessel formed by the surgeons: the outflow of blood from the right lung does not meet any obstacles on the way, there are no thromboses, the pressure in the pulmonary system decreased by 1.5 times. The teenager returned to his studies.[2]

For the first time in Russia, a child was installed a heart valve from donor tissues
In November 2022, in the center of congenital heart defects and pediatric cardiorematology of the Samara Regional Clinical Cardiological Dispensary named after V.P. Polyakov, for the first time in Russia, a unique operation was performed - a homograph valve was installed. This is an implantable prosthesis consisting of specially treated donor tissues of the patient.
The patient was an 8-year-old boy who had an atrial ventricular septal defect at birth. When he turned six months old, the doctors installed an artificial valve on his heart, and when the child grew up, the valve had to be changed. After such an operation, patients need to constantly take blood-thinning drugs, and the child has to live with certain restrictions. Therefore, Samara children's cardiac surgeons decided to install a valve from donor tissues to the boy - a homograph.
| | This is the latest development of scientists from St. Petersburg. The new valve will allow him to lead a normal lifestyle, without additional drugs. We are satisfied with the result, immediately on the operating table we made a control EGC through the esophagus and assessed the work done. I hope our new experience will give an impetus to the replication of such an operation with this pathology, - explained the head. Department of Cardiac Surgery and Cardiorematology, SOKKD named after V.P. Polyakova Sergei Shorokhov. | |
The operation, carried out by Samara cardiac surgeons, was technically complex and lasted about 4 hours. Now the child can live a full life and engage in physical education and sports. The operation was carried out free of charge as part of a high-tech medical care program, according to the information policy department of the Samara region.
| | Now the son can play sports, physical activity. I am very grateful to the doctors. The most important thing is to believe in your child, and believe the doctors who will do everything so that everything is fine with the child, - said the boy's mother Angelina.[3] | |
World's first partial heart transplant performed
In early September 2022, a team of specialists from the Duke Health Clinic performed the world's first partial heart transplant, in which living arteries and valves from a fresh donor heart were connected to the patient's existing heart.
The goal of the surgery was to allow the valves to grow with the pediatric patient over time, increasing life expectancy. The team believes a similar approach could be used to install new donor heart valves to countless other children with heart defects.
The operation was performed on newborn Owen Monroe, weighing 2.26 kg. His family hails from North Carolina State, but he was born in Duke after his parents learned he had a condition called congenital heart disease, in which his two main heart arteries were fused together. Worse, his one vessel was fitted with a leaky valve, making it unlikely that Owen could survive the wait for a full heart transplant.
Usually, children in situations like Owen's have two preserved cadaveric arteries transplanted with valves. But the implanted tissue used in this procedure does not grow with the child's own heart because it is not alive. Pediatric patients require several follow-up open-heart surgeries to replace the valves with larger ones, significantly reducing their lifespan.
In a partial heart transplant, Joseph Turek, MD, PhD, and a team from Duke Health Clinic, including pediatric cardiac surgeon Nicholas Andersen, MD, and a large team of anesthesiologists, nurses, technicians and support staff, used live tissue and valves. The tissue was obtained from a donor heart that had strong valves but could not be used for a complete transplant due to the muscle condition. The team's efforts to implant valves that can grow with the patient have been successful. After the surgery, performed on 22 April 2022, Owen is showing significant growth and improvement and his prognosis remains favourable.
Experts at Duke Health Clinic hope a similar approach could be used to treat common cases of valve replacement in children by performing a one-time operation to implant fresh donor tissue that can grow with the child.[4]

Russia carried out the world's first operation on the aortic valve of the heart without a chest incision
Cardiac surgeons Meshalkin National Medical Research Center Novosibirsk in performed the world's first valve operation aortas hearts without a chest incision. This was reported in the clinic in September 2021.
Successful surgical treatment was performed on a 36-year-old patient with heart aortic valve disease and aneurysmally dilated aorta. The patient has not a three-, but a bicuspid valve of the heart. He began to let in blood, the condition worsened, so the doctors decided to operate. The patient's aorta was positioned to extend beyond the edge of the sternum.
| | This is always a clue to the surgeon that miniinvasive access can be made on the right side. It seems to everyone how so? The heart ─ on the left, and access ─ on the right. You can do it on the right along the intercostal interval, ─ explained Alexander Bogachev-Prokofiev, director of the Institute of Circulatory Pathology of the National Medical Research Center named after Meshalkina. | |
According to him, the anatomical feature provided an opportunity to avoid partial sternotomy (sternal dissection), preserving its integrity, and perform the entire volume of intervention through access in the second intercostal space along the front surface of the chest. A technically complex intervention through a small 6.5 cm access was allowed by the accumulated experience in the field of mini-invasive technologies and aortic surgery, he said.
According to the doctors of the clinic, the advantage of this technology is the complete preservation of the bone structures of the sternum. This reduces the risk of infectious complications after surgery. They also note that after the operation there is rapid rehabilitation.
During the operation, surgeons eliminated the sagging of both valve valves - they collected their free edges with several sutures and narrowed the diameter of the fibrous ring to normal values. Also, doctors replaced the dilated part of the aorta with a vascular prosthesis with the preservation of the patient's aortic valve.[5]

Surgeons in the Moscow region performed a unique operation to remove a tumor on the open heart
In July 2020, it became known about a unique operation in the Moscow region to remove a tumor on the open heart. Doctors of the Moscow Regional Research Clinical Institute named after Vladimirsky (MONICA) rescued a resident of Zhukovsky near Moscow.
A tomographic study revealed in a 56-year-old resident of the city of Zhukovsky near Moscow a tumor-like formation of the right lung measuring more than 6 centimeters. It turned out that her disease had been secretive for a long time and manifested itself only in the summer of this year in the form of a severe cough. According to the results of fluorography, the patient was diagnosed with medial pneumonia.
After the consultation of MONICA doctors, it was decided to urgently perform video thoracoscopic surgery, since a massive malignant tumor affected most of the right lung, actively sprouted into the mediastinum and pericardium. That is, she affected the activities of the heart and threatened the patient's life. Since the tumor passed through all the layers of the anterior wall of the right atrium, surgeons had to do jewelry work on the open heart and without the use of an artificial circulation machine, otherwise the progressive decay of the tumor could lead to fatal bleeding.
An economical thoracotomy was performed, most of the anterior wall of the right atrium was resected, and the entire right lung with all mediastinal lymph nodes was removed. The operation, which was carried out by the head of the thoracic department of MONICA, Professor Alexander Allakhverdyan, lasted just over three hours, and the blood loss was less than 300 milliliters. Immediately after the operation, the patient was transferred to independent breathing with a complete restoration of consciousness, and a day later she could independently move around the department.[6]
