Abstract
Severe calcific mitral valve stenosis can rarely occur concomitantly with obstructive hypertrophic cardiomyopathy. In these patients, surgical decalcification of the stenotic mitral valve followed by mitral valve replacement carries substantial operative risk and may result in paravalvular leakage, atrioventricular groove disruption, and excessive bleeding. We report two cases of obstructive hypertrophic cardiomyopathy with severe calcific mitral valve stenosis successfully treated with concomitant transaortic septal myectomy and bypass of the stenotic mitral valve with the use of a valved left atrial-to-left ventricular conduit.
