HYPERTROPHIC OBSTRUCTIVE CARDIOMYOPATHY IN COMBINATION WITH ANOMALOUS INSERTION OF PAPILLARY-MUSCLE DIRECTLY INTO ANTERIOR MITRAL LEAFLET AND SAWFISH SYSTOLIC NARROWING OF THE LEFT ANTERIOR DESCENDING CORONARY-ARTERY

This report describes an unusual case of subaortic stenosis in which hypertrophic obstructive cardiomyopathy was found in combination with both anomalous insertion of papillary muscle directly into the anterior mitral leaflet and ''sawfish'' systolic narrowing of the left anterior descending coronary artery. Definitive diagnosis was made on operation. We freed the left anterior descending coronary artery by incising the muscular bridge, resected both papillary muscles, and replaced the mitral valve.
