METHOD FOR RADICAL CORRECTION OF CONGENITAL DOUBLING OF OUTLET OF RIGHT VENTRICLE WITH ELIMINATION OF SIZE MISMATCH OF ASCENDING PART OF ARCH AND ROOT OF NEOAORTA IN OPEN CORONARY ARTERY REIMPLANTATION Russian patent published in 2024 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to cardiac surgery. A median sternotomy is performed, the main arteries are separated and mobilized, the open arterial duct is sutured and transected. An ascending aorta is transected and a pulmonary artery bifurcation is dissected above the valve commissures, the interventricular defect is closed by a synthetic patch with tunneling of the neoaorta and left ventricle. A U-shaped segment of the non-coronary sinus wall is excised, not reaching 5 mm to the fibrous ring of the neoaorta, followed by reconstruction with a continuous vascular suture and plastic expansion of the ascending aorta with a separate pericardium patch, supplemented by reimplantation of coronary arteries by open technique, and restoration of integrity of great vessels.

EFFECT: method enables eliminating the mismatch between the diameters of the aortic root and the pulmonary artery without a risk of deformation of the neoaortic sinuses when using the open technique of coronary artery reimplantation.
