[Diagnosis and evaluation of mitral endocarditis complicating obstructive cardiomyopathy using cardiac echo-Doppler]

The authors report a case of mitral endocarditis diagnosed by cardiac echo-Doppler and complicating an obstructive cardiomyopathy (OCM) in a 37-year-old woman. Despite the high degree of sub-aortic obstruction and the existence of an apparently severe mitral leak by Doppler analysis, the patient remained totally asymptomatic and the outcome was favourable with appropriate antibiotics. A review of the literature revealed 11 cases of endocarditis in a context of OCM, documented by echocardiography. Echo-Doppler enables precise evaluation of this grave and often poorly tolerated complication of OCM.
