Ebstein's anomaly in adult.

Ebstein's anomaly is a rare congenital cardiac disease initially described by Wilhelm Ebstein in 1866. It is defined as the significant apical displacement of the part of the tricuspid valve causing significant tricuspid regurgitation and reduction of the functional right ventricle, right atrial and right ventricular dilatation and atrial and ventricular arrhythmias. Ebstein's anomaly occurs approximately once in 20,000 live births and only 5% of patients survive beyond the fifth decade. We present a case of Ebstein's anomaly in a 69-year-old Italian woman. Also this case is illustrative of Ebstein's anomaly in adult.
