Subvalvular membranous aortic stenosis: Results of surgical therapy

AUTOR(ES)
RESUMO

Subvalvular membranous aortic stenosis is usually accompanied by mild aortic insufficiency. This insufficiency is probably caused not by the valves but by the membrane. Resection of the membrane generally produces satisfactory results so far as the stenosis is concerned, and causes no significant aggravation of the insufficiency.
