Highlights a rare case of mitral infective endocarditis complicating hypertrophic obstructive cardiomyopathy.
May prompt endocarditis vigilance in hypertrophic obstructive cardiomyopathy with acute regurgitation; leaves open incidence and risk-factor questions.
Endocarditis complicating hypertrophic cardiomyopathy (HCM) is rarely reported. The estimated cumulative 10 year probability of developing endocarditis in obstructive HCM is <5%. It's estimated incidence is 1.4 per 1000 person/year in all patients and it increases to 3.8 per 1000 person/year in patients with left ventricular outflow tract obstruction. Studies examining mitral valves from such patients with endocarditis have found vegetations most commonly on the left ventricular aspect of the anterior mitral valve leaflet, presumably caused by mitral-septal contact during systole. We report a case of a 56-year-old man who was admitted for mitral infective endocarditis resulting in severe mitral regurgitation complicating a hypertrophic obstructive cardiomyopathy. We reviewed the literature and discuss the treatment options under such circumstances.
