Mitral stenosis and hypertrophic obstructive cardiomyopathy: An unusual combination

Systolic anterior motion of mitral valve (MV) leaflets is a main pathophysiologic feature of left ventricular outflow tract (LVOT) obstruction in hypertrophic obstructive cardiomyopathy. Thus, restricted leaflet motion that occurs with MV stenosis might be expected to minimize outflow tract obstruction related to systolic anterior motion.From January 1993 through February 2015, we performed MV replacement and septal myectomy in 12 patients with...
