[Ebstein's malformation. Report of 9 cases surgically treated (author's transl)].

Nine patients with Ebstein's malformation have undergone surgical repair since 1971. Their ages ranged from 10 to 49 years. Two patients were in functional class II and six in III. Dysrhythmias were indicators for operation in the remaining patient. All patients underwent prosthetic valve replacement. Other procedures included atrial septal defect closure in eight and plication of the atrialized ventricular segment in four cases. Three patients died during the postoperative period. Three patients died during the postoperative period. Functional classification improved in five of the six operative survivors. The multiple aspects of the clinical features, the different surgical management and the variability of results are explained by the wide range of morphologic and functional aspects of the malformation.
