Clinical Presentation and Therapy of Ebstein Anomaly

Abstract

Ebstein anomaly is a rare congenital heart defect, accounting for less than 1% of cardiac malformations and occurring in approximately 1 out of 210,000 live births. It is characterized by an abnormality of the tricuspid valve, where the valve is positioned lower than normal in the right ventricle. Although primarily a tricuspid valve defect, the right ventricle itself is often structurally abnormal and weakened (myopathic).
