Ebstein's anomaly (EA), a rare congenital heart disease, results from the failure of delamination of tricuspid valve (TV) leaflets from the endocardium of the right ventricle (RV) and apical displacement, particularly of the septal and posterior leaflets of TV. The most commonly accompanying cardiac malformation is atrial septal defect. Most EA cases are sporadic; familial ones are rare. EA patients may present at any age. Symptoms result from TV regurgitation, RV dysfunction, inadequate left ventricular filling owing to ventricular septal bowing, inadequate pulmonary flow, and arrhythmias. Atrial tachyarrhythmias are the most common late complications. There have been more techniques of tricuspid repair reported in the literature than any other congenital or acquired cardiac lesion.Neonatal operation has a higher risk of mortality than the operations performed beyond infancy. Late survival rate and the quality of life for hospital survivors are excellent.
