[Initial experience with the surgical treatment of hypertrophic cardiopathy using an apico-aortic valved conduit].

Long-term results (up to 3 years) of operative treatment of first patients with complex obstruction of the left ventricle outflow tract (hypertrophic cardiomyopathy--10 patients, congenital subaortic tunnel stenosis--1 patient) with the help of apico-aortic valved conduit are presented. There was no intrahospital lethality. Two patients died in late terms after operation who had been operated upon for the III degree of circulation insufficiency. Complications associated with using the valved conduit were not noted. All the patients operated upon did not need medicamentous therapy (indirect anticoagulants excluded), seven of them had the 1st functional class NYHA by the moment of examination, two had the 2nd functional class. Continuous observations have revealed a marked tendency to normalization of the hemo- and cardiodynamic parameters.
