Surgical Management of Ebstein's Anomaly in the Adult

Ebstein's anomaly is a rare cardiac malformation that affects the tricuspid valve, right ventricle, and right atrioventricular junction. These anatomical and functional abnormalities cause important tricuspid regurgitation that results in right atrial and right ventricular dilatation and atrial and ventricular arrhythmias. Diagnosis is made by echocardiography. Operation includes tricuspid valve repair or replacement, closure of any interatrial communications, and appropriate antiarrhythmia procedures. Repair of Ebstein's anomaly eliminates right-to-left intracardiac shunting, improves exercise tolerance and functional class, and reduces supraventricular arrhythmias. In addition, quality of life and longevity are improved. © 2005 Elsevier Inc. All rights reserved.
