Abstract

We report a case of infective endocarditis (IE) involving the posterior mitral leaflet (PML) with calcific embolization in a patient with hypertrophic obstructive cardiomyopathy (HOCM). Amongst HOCM patients with IE, the anterior mitral leaflet and basal septal myocardium are almost always involved due to the endocardial damage caused by recurrent outflow obstruction and valvular regurgitation. The management of our patient was complicated by moderate mitral stenosis, repeated calcific embolic strokes, dynamic left ventricular outflow track obstruction, and respiratory failure due to flash pulmonary edema. To our knowledge, this is the first reported case of PML involvement in HOCM presenting in this manner.
