FIELD: medicine; cardiosurgery.
SUBSTANCE: artificial circulation is connected by bicaval technique. Right atrium is opened on a parallel artificial circulation. Incision is made from top to bottom at the border between the middle third and outer third closer to the vena cava inferior, crossing the border furrow. Following lines are made: 1—to superior vena cava; 2—to vena cava inferior; 3—on the tricuspid valve ring. Exposure time is 1.5 minutes. Aorta is clamped. Upon termination of cardioplegia, left atrial (LA) appendage is resected. Left atrium is opened through the Sondergaard's groove. Following lines are made: 1—on LA roof; 2—along the diaphragm surface of the LA, forming a "box" ("box-lesion"); 3—on mitral isthmus in projection P2–P3 of segments of posterior cusp of mitral valve, exposure time—2.5 minutes; 4—per coronary sinus, epicardial, 1.5 minutes. Resected eye is closed, the valve apparatus is operated, and the chambers are sealed. Artificial circulation is switched off.
EFFECT: method enables to reduce the risk of developing cardiac conduction disorders in the postoperative period, risk of developing complications associated with prolonged artificial circulation, as well as patient cooling, minimize risk of recurrent seizure factors.
