Combined Heart-kidney Transplantation: A Single Center Experience

Introduction: We report our experience with seven cases of combined heart-kidney transplantation (HKT). Patients and methods: Between January 2003 and December 2009, seven subjects underwent combined HKT, receiving both organs from a single donor. Their age ranged from 30 years to 59 years, six were male. Five patients were dialysis dependent before transplantation and two were in chronic renal failure (serum creatinine levels > 2.6 mg/dL). The heart was transplanted first in all cases. Results: Heart function rapidly re-covered in five of the patients, while two needed temporary inotropic and mechanical support. Diuresis started immediately in four patients. At discharge, all patients had well-functioning grafts (left ventricular ejection fraction 60% ± 6%; serum creatinine 1.4 ± 0.3 mg/dL). After an average follow-up period of 45 ± 24 months no deaths have occurred. Heart allografts are functioning normally in six patients and none of the patients currently require dialysis treatment. The main adverse event noted during follow-up was hypertension in five patients. Four patients were cardiac allograft rejection free and five patients were kidney rejection free. Conclusion: Our results are in line with the data which has been previously reported in the literature and suggest that HKT is a viable therapeutic choice in the treatment of advanced cardiac and renal failure in carefully selected patients.
