INTRODUCTION
The anterior mitral leaflet cleft (AMLC) is a rare congenital anomaly and is often associated with other congenital heart diseases. It may be seen with ostium primum atrial septal defect, ventricular septal defect, tetralogy of Fallot, transposition of the great arteries, double outlet right ventricle, tricuspid atresia and double inlet left ventricle. The isolated AMLC is a very rare anomaly. Echocardiographic imaging is the mainstay diagnostic tool for demonstrating the cleft, identifying other congenital heart anomalies, and determining the severity of mitral regurgitation. Mitral cleft is a surgically correctable anomaly. Valve repair should be preferred over valve replacement in suitable patients. (1-3)
In this case report, two cases with isolated AMLC are presented with their echocardiographic diagnosis and follow-up.
