SURGICAL METHOD FOR TREATING THE CASES OF LEFT VENTRICLE OUTLET SEGMENT OBSTRUCTION AGGRAVATED BY INTERVENTRICULAR SEPTUM HYPERTROPHY

摘要

FIELD: medicine. SUBSTANCE: method involves applying cross-sectional dissection of interventricular septum area having asymmetrical hypertrophy from conic portion of right cardiac ventricle anterior to conic muscle (Lancisi) without penetrating into left ventricle cavity under control of surgeon finger introduced through opened ascending aorta. Dissection is carried out not deeper than by 2/3 of interventricular septum thickness to the level required for achieving obstruction hypertrophy zone relaxation. EFFECT: no invasion into left ventricle cavity.
