Ebstein’s Anomaly

Last updated December 2021

This condition means that there are problems with the tricuspid valve, the valve between the collecting chamber (atrium) and pumping chamber (ventricle) on the right side of the heart. The valve has not formed properly and may well have caused the collecting chamber (right atrium) to be bigger than normal and the pumping chamber (right ventricle) to be much smaller than normal. The surgeons will always try to keep the valve and chambers working as normal but sometimes the ventricle is not big enough and they will offer a treatment path similar to that offered for Tricuspid Atresia.
