[Mitral regurgitation in infective endocarditis]

Endocarditis affecting the mitral valve is frequent and is associated with specific features. Mitral prolapse is the most frequent underlying disease and the mechanism of mitral regurgitation secondary to infective endocarditis is frequently complex and multiple. Echocardiography plays a key-role in both the diagnosis, the prognostic assessment and the choice of the best therapeutic option in patients with mitral valve endocarditis. Surgery is frequently necessary, and must be performed early in the course of the disease. Mitral valve repair is the best therapeutic option, when technically possible.
