Ebstein anomaly is a congenital cardiac defect of Right sided valve called Tricuspid valve.
here Septal part of valve is displaced down so Right ventricle becomes small and Right atrium gets larger volume. As Leaflet is not in normal position Valve leaks every time when heart beats.
so more and more blood come back to Right atrium ,which suppose to go to Right Ventricle.
associated defect like ASD also present .
here I have shown one of our Pt operated for Ebstin anomaly with Tricuspid valve repair
