METHOD OF CREATING CONTROLLED INTERATRIAL COMMUNICATION IN SURGICAL CORRECTION OF CONGENITAL HEART DEFECTS Russian patent published in 2024 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention relates to cardiosurgery. Atrial defect is closed with a pericardium patch, at the base of which an arc-shaped incision is made at the right edge to form a movable flap. One U-suture is delivered through the flap, the suture ends of which are brought out into the area of the interatrial sulcus outside the heart, tied on a padding and taken into a tourniquet. Venous catheter is introduced through the arched incision to vary the pressure in the left atrium. Heart cavities are sealed; a test closure of the interatrial communication is performed by temporarily tightening the tourniquet. If observing cardiac failure and increased pressure in the left atrium, the interatrial communication is left functional by pulling the U-suture outwards and removing the spacer. In the absence of data for cardiac failure and normal pressure in the left atrium, the interatrial communication is eliminated by tying a U-suture on the lining outside the heart by removing the tourniquet.

EFFECT: method enables normalizing the haemodynamic function of the unidirectional controlled interatrial communication with the effective possibility of eliminating it when the necessary conditions appear.
