FIELD: medicine.
SUBSTANCE: performing a full venous bypass of the right heart and combined annulo-valvuloplasty of the common atrioventricular valve. At first, the patch is fixed to the valve bridging leaflets with continuous suture at the level of interventricular septum crest projection, and then it is sutured along the perimeter to annulus fibrosus of the sutured valve component. Synthetic semiring is fixated with continuous suture to the fibrous ring of the remaining valve component, providing pleat compilation of the annulus fibrosus so that the diameter of the formed valve is not smaller than the size of the mitral valve according to the operated child age norm. While fixating the semiring, coronary sinus region is excluded from the suture region.
EFFECT: method allows to reliably eliminate regurgitation due to separate plastic of two valve components, to prevent the complications caused by prolonged cardiac arrest, to create anatomical conditions for prosthetics of a common AV valve.
