Combined cardiorenal transplant in heart and advanced renal disease

Abstract

Introduction: Renal failure (RF) is a post cardiac transplantation predictor of morbimortality. The combined cardiorenal transplant (CCRTx) in cardiac transplantation (CTx) candidates with chronic renal disease is a therapeutic option. Our aim was to evaluate the CCRTx follow up outcomes in a single Centre. Methods: Between 2/1993 and 12/2014 we performed 442 CTx. Since 2006, 20 patients (p) underwent CCRTx using allografts from the same donor. The inclusion criteria were: RF with CrCl ≤ 40 mil/min or dialysis requirement in CTx candidates. All p received Thymoglobulin and immunosuppression with tacrolimus, mycophenolate mofetil and steroids.Median follow up: 46 months (7-96). Results: Mean age: 58±7 years, 85% were male. Mean Creatinine (Cr): 3,1±2,5 mg/dl and ClCr 27,5+10 mil/min. Three p required dialysis during the pre-transplantation phase and 4 p were under chronic dialysis. Etiologies: cardiomyopathies: coronary 10 p, noncoronary 9 p and re CTx, 1 p; nephropathies: nephroangiosclerosis 5 p, cardiorenal syndrome 10 p, diabetes 2 p, glomerulopathy 1 p, polycystosis 1 p and toxic nephritis 1 p. At 30 days and 1 year post CCRTx, Cr was 1,2±0,4 mg/dl and 1,1±0,2 mg/dl respectively. In-hospital mortality was 3/20 p (15%), 2 p due to sepsis and 1 p due to cardiac graft failure. Late mortality 5/17 p (29 %), 4p due to sepsis and 1 p due to liver sarcoma. Survival at 1 and 3 years was 76 and 72%, respectively. Conclusions: In our series CCRTx was a safe and effective treatment for CTx candidates with CrCl < 40 ml/min.
