Cardiac surgeons from Sechenov University operated on a 14-year-old boy with a heart defect without the classical installation of a prosthesis. He was given a “Russian conduit,” said the head of the department of faculty surgery No. 1 of the Institute of Clinical Medicine named after. N.V. Sklifosovsky First Moscow State Medical University named after. THEM. Sechenov Roman Komarov. He is quoted by the Moscow City News Agency.
For a boy with an aortic defect and a wide fibrous ring, a wide ascending aorta, with a standard approach, a mechanical valve prosthesis and a prosthesis of the ascending aorta would be installed, Komarov explained.
“We went the other way and performed the “Russian conduit” operation, which was patented by us and is successfully used in adults. We sewed valve petals from the pericardium into the ascending aorta prosthesis; this structure is sewn into the left ventricle,” said the cardiac surgeon.
He noted that this was the first child to undergo such an operation in our country. This operation makes it possible to live a normal life without restrictions.
Last summer, Komarov said that the faculty surgery clinic had developed a “Russian conduit.” The operation involves cutting out valve leaflets from the patient’s own pericardium and implanting them into an aortic prosthesis before the heart stops, which reduces the time of cardiopulmonary bypass by half. This “new aortic root” is then reimplanted into the aortic root position.
“The operation is done according to the scheme: I came with a problem and left without a problem and no medications!” – the doctor said then.
According to him, previously it seemed that in patients with aortic valve stenosis and aneurysm of the ascending aorta there was no alternative to classical valve replacement. But this means lifelong use of specific drugs, in which the blood becomes 2-3 times more liquid than in healthy people. “This means you can’t get pregnant or give birth, you can’t play sports, the risk of bleeding during bruises, dental and other procedures is very high,” Komarov explained.
And in 2019, cardiac surgeons at the university clinic performed an operation using the Ozaki method to treat congenital aortic stenosis in a 7-year-old boy. This technique is used extremely rarely in pediatric surgery.
