Successful heart transplantation with acquired pulmonary artery atresia

Orthotopic cardiac transplantation was performed successfully in a patient with acquired atresia of the left pulmonary artery 19 years after repair of tetralogy of Fallot. Only the right lung could be incorporated into the cardiopulmonary circulation at transplantation, resulting in transient right ventricular dysfunction, which resolved with vasodilator therapy. Perfusion of a single pulmonary vascular bed does not preclude successful heart transplantation, provided there is a low pulmonary vascular resistance and pulmonary artery architecture free of stenoses.
