Combined Heart and Liver Transplantation for Uhl's Anomaly: A Case Report

Uhl's anomaly is an extremely rare congenital heart defect characterized by absence of the right ventricle myocardium and preserved left ventricular myocardium. Although the disease has a poor prognosis and is generally fatal in the perinatal period, some patients may reach adulthood.

We describe a case of Uhl's anomaly complicated with heart failure and decompensated cardiac cirrhosis in a 42-year-old man treated by combined heart-liver transplant.

The patient underwent heart transplant using the bicaval technique followed by subsequent liver transplant with the piggyback technique without venovenous bypass. Total ischemia time was 108 minutes for the heart and 360 and 25 minutes of cold and warm ischemia, respectively, for the liver. No intraoperative complications occurred. The patient was discharged without severe complications on postoperative day 22. Pathologic examination of the organs reported advanced cirrhosis of the liver and severe dilated myocardiopathy of right ventricle with absence of myocardium and a normal left ventricle. Twenty-seven months after the transplant the patient has been free from hospital admissions, with normal function of both transplanted organs.

We report the first successful combined heart-liver transplant for Uhl's anomaly indication in an adult patient. Despite of the insufficient knowledge of natural history of this exceptional disease, we successfully apply the management principles of other end-stage right heart disorders complicated with liver failure.
