Heart/single-lung transplant for a "failed Fontan" with pulmonary A-V malformation.

Abstract

Pulmonary arteriovenous malformation can occur in patients with functional single ventricle after a cavopulmonary connection. There is no effective medical treatment for this complication. Pulmonary arteriovenous malformations may regress over time after heart transplantation, but may be a source of significant perioperative morbidity. We report the case of a woman with single ventricle, ventricular dysfunction, and bilateral pulmonary arteriovenous malformations who had successful treatment of both cardiac and pulmonary failure with en bloc heart and right lung transplantation.
