N2 - OBJECTIVE: In selected patients with severe end-stage combined cardiopulmonary diseases, heart-lung transplantation (HLTx) remains the only therapeutical option for improving survival and quality of life.PATIENTS AND METHODS: Since 1983, 51 HLTx were done at our institution. Mean patient age was 27+/-12 years with a mean donor age of 25+/-11 years. Indications for HLTx were primary pulmonary hypertension (PPH) in 49% of patients, congenital heart disease in 39%, cystic fibrosis in 6%, and repeat-HLTx in 6%. Eleven patients were younger than 14 years. Among these pediatric patients, the indications were PPH in 55% of patients, pulmonary atresia with severe pulmonary artery hypoplasia in 27%, and cystic fibrosis and cardiomyopathy with fixed pulmonary hypertension in 9% of patients each. Two patients had additional liver transplantation because of chronic aggressive virus hepatitis. For organ preservation, Euro-Collins solution (lung perfusion) and cardioplegic solution according to Bretschneider (heart perfusion) were used until 1994. The University of Wisconsin solution replaced Bretschneider's solution in 1994. Since 1996, Perfadex, a low-potassium dextran-based preservation solution, replaced Euro-Collins. All transplantations were done through a median sternotomy until 1994. Thereafter, a transverse thoracotomy was used in patients with suspected adhesions. Until 1995, cyclosporine A, azathioprine, and prednisolone were used for immunosuppression. Since then, tacrolimus replaced cyclosporine A.RESULTS: From 1983 until 1993, perioperative mortality was 35% (6/19). From 1994 on perioperative mortality decreased to 12.5% (4/32). Early mortality was caused by graft failure (n=5), severe bleeding (n=2), multi-organ failure (n=2), and acute rejection (n=1). Cumulative survival rates were 81% after 30 days, 63% after 1 year, and 54% after 5 years, respectively. Since 1994, cumulative survival rates were markedly improved to 87% after 30 days, 81% after 6 months, and 78% after 1 year. There was no death during the first postoperative year among the 11 pediatric patients. Late death was mainly caused by obliterative bronchiolitis (OB; 76%); two patients died because of multi-organ failure or septic complications, respectively, and one patient died within the first postoperative year because of aspergillosis.CONCLUSION: Changes in organ preservation management, surgical techniques, and immunosuppressive therapy significantly improved the short- and mid-term results after HLTx. Long-term results can only be improved in cases of successful prevention and treatment of OB.
