Heart transplantation in patients with extreme right ventricular failure.

OBJECTIVE Donor shortage and improved medical treatment of heart failure increase the prevalence of patients with extreme right ventricular failure and ascites to heart transplantation. The clinical outcome of heart transplantation in these patients has rarely been reported. Here, we sought to evaluate the clinical outcome of heart transplantation in patients with extreme right ventricular failure and refractory ascites. METHODS Data were collected by retrospective chart review. RESULTS Between 1993 and 2005, 12 patients with extreme right ventricular failure and refractory ascites underwent orthotopic heart transplantation at the authors' hospital. The causes of heart failure were congenital heart disease in four patients, dilated cardiomyopathy in two patients, rheumatic heart disease in two patients, coronary artery disease in two patients, and restrictive cardiomyopathy and transplant coronary artery disease each in one patient. Eight of 12 patients had previous cardiac operation. The findings of preoperative abdominal sonography were massive ascites in all patients, congestive liver in 11 patients, and probably cardiac cirrhosis in 1 patient. One patient underwent combined heart and kidney transplantations. There were six in-hospital deaths: bleeding in three patients and multiple organ failure in three patients. Major postoperative complications occurred in 10 patients: renal failure requiring dialysis in 9, bleeding requiring reoperation in 8 patients. Patients with previous cardiac operation had a higher mortality rate (5/7 vs 1/5). CONCLUSIONS Heart transplantation in patients with extreme right ventricular failure and refractory ascites was associated with high mortality and morbidity. The presence of previous cardiac operation implied even poor prognosis.
