FIELD: medicine; cardiovascular surgery.
SUBSTANCE: first stage involves plasty of interventricular septum defect with polytetrafluoroethylene patch, which is hemmed with continuous blanket suture. Upper edge of the interventricular patch is attached to the upper and lower cusps of the common atrioventricular valve with a suture line displaced by a tricuspid portion of 0.3–0.5 cm. Plasty of splitting anterior cusp of mitral valve is performed with single U-sutures. At the final stage, the septal cusp of the tricuspid valve is repaired with single interrupted sutures.
EFFECT: method enables reducing a risk of intra- and postoperative complications, namely stenosis of the left ventricle, insufficiency or stenosis of the mitral valve, as well as avoiding valve replacement.
