FIELD: medicine, cardiosurgery. SUBSTANCE: artificial circulation is launched due to cannulation of aorta, cross-sectional vein and inferior vena cava at its bottom. Superior vena cava is crossed cross-sectionally at the level of right pulmonary artery. The latter is lanced longitudinally both along superior and inferior edges. Distal end of superior vena cava is anastomosed with superior edge of pulmonary artery by "the end-into-the side" technique. Proximal end of superior vena cava is anastomosed with inferior edge of pulmonary artery by the same technique. One should longitudinally lance right atrium and with the help of a patch form a tunnel between the bottoms of inferior vena cava and superior vena cava by keeping coronary sinus in left atrium. Exit from right ventricle is closed by ligating the trunk of pulmonary artery. Right ventricle is lanced in outflowing department in nonvascular area. One should carry out revision of interventricular septum defect to close it. At defect's size being below 1 cm it should be closed due to simple suturing by separate P-shaped sutures upon interlayers. At its size being above 1 cm - one should carry out defect's plasty due to applying a patch with separate P-shaped sutures. The suggested method enables to develop optimal conditions for functioning of left ventricle as a result of its isolation from lateral cavities. EFFECT: higher efficiency. 2 cl, 2 ex
