title: Unique congenital malformation of the mitral valve associated with anomalous coronary arteries and stroke.
abstract: A 55-year-old male presented with stroke. Transesophageal echocardiogram and cardiac computed tomography revealed an unrecognized congenital malformation of the anterior mitral leaflet associated with anomalous left coronary circumflex artery, arising from the right coronary artery, diagnosed first by echocardiogram. This case represents a unique unforeseen mitral valve anomaly that might be considered as potential cardiac source of embolism. This finding broadens the spectrum of known mitral valve anomalies.
