Asymptomatic Mitral Regurgitation Caused by an Isolated Mitral Leaflet Cleft in a Young Adult: A Case Report

We report the case of an 18-year-old young man without previous medical history, who was referred for evaluation asymptomatic cardiac murmur. Physical examination found holosystolic 4-5/6 apical murmur with normal ECG. Bidimensionnal (2D) echocardiography revealed severe mitral regurgitation thin leaflets. Three dimensional (3D) Echocardiography done better assessment valve mechanism isolated leaflet cleft, signs endocarditis or traumatic lesion. Regarding absence symptoms and excellent maximal exercise tolerance at stress echocardiography, a repair surgery wasn’t offered. Isolated cleft is rare congenital anomaly, in adults, may be incidental finding that remains years when leak well tolerated. 2D combined 3D key diagnosis guidance.
