Surgical Management for an Adult Female Patient With Ebstein Anomaly of the Tricuspid Valve With a Subvalvular Membrane With Severe PS and Multiple VSDs: A Case Report

Ebstein's anomaly is a rare and complex heart defect that affects the tricuspid valve and is accountable for around 1% of congenital cardiac abnormalities. It is one of the most common congenital causes of tricuspid valve regurgitation. Ebstein's anomaly often is diagnosed prenatally, due to its severe cardiomegaly. Some individuals with this anomaly do not experience complications until adulthood and even then, they have mostly minor complaints like exercise intolerance. Atrial septal defect is most commonly (70-90%) associated with Ebstein's anomaly. However, ventricular septal defect (VSD) can be associated with 2-6% of the cases. This report presents a case of surgical intervention for a 20-year-old female with Ebstein's anomaly with severe pulmonary stenosis (PS) and multiple VSDs.
