FIELD: medicine; cardiosurgery.
SUBSTANCE: performing separation and mobilization of an aortic arch with branches and a descending part of a thoracic aorta behind a zone of arc interruption. Further, the ascending and descending parts of the aorta are cannulated; the cannula is brought into the descending part of the aorta. After the ascending aorta is cross-clamped, a U-suture is applied on the conical septum from the side of the output part of the left ventricle. Then the interventricular defect is closed with a patch that is fixed along the perimeter, except for the area adjacent to the conical septum. Conical septum is pulled forward to the interventricular defect patch by the previously applied U-suture on the gasket. Thereafter, sutures of the U-suture are inserted into the upper edge of the patch and pricked out through the patch towards the right ventricle. Then the suture is tightened, fixing the patch; after sealing the heart chambers, the clamp is removed from the ascending aorta and the operation is completed.
EFFECT: method enables minimizing the invasiveness of the intervention on the conical septum without increasing the complexity of the underlying defect correction, to bring hemodynamics of the left ventricle and aorta closer to the norm, as well as to avoid severe postoperative consequences.
