METHOD OF BLOOD CIRCULATION CORRECTION IN PATIENTS WITH FUNCTIONAL SINGLE VENTRICLE AND GENERAL ATROVENTRICULAR VALVE INSUFFICIENCY Russian patent published in 2017 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: at first, valve component is sutured with the highest hypoplasia ratio, and then it is closed with a synthetic patch. 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 enables to eliminate regurgitation due to separate plasty of two valve components, perform the prevention of complications caused by prolonged cardiac arrest, as well as complications associated with cardiac arrhythmia, as well as to create new anatomical conditions for general AV valve prosthesis.
