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.

In this case report, two cases with isolated AMLC are presented with
their echocardiographic diagnosis and follow-up.
