The role of intraoperative transesophageal echocardiography in the successful outcome after mitral replacement for infective endocarditis on the background of hypertrophic obstructive cardiomyopathy: a case report.

Hypertrophic cardiomyopathy is most commonly an autosomal genetic disorder characterized by increased morbidity. Infective endocarditis, although rare, can complicate the course of the disease. The mitral and aortic valves are more commonly affected. Mitral valve vegetations may cause severe regurgitation and acute heart failure. In the event that the anterior valve leaflet is affected, this may result in severe left ventricular outflow tract obstruction (LVOTO), requiring immediate intervention and resulting in a significant increase in mortality. We report a rare clinical case of a patient with hypertrophic cardiomyopathy complicated by mitral valve infective endocarditis and LVOTO.
