OBJECTIVE: To evaluate operative management, outcome, and long-term survival in patients with functioning renal and hepatic allografts who underwent cardiac surgery. PATIENTS AND METHODS: We studied all patients who had previously undergone either renal or hepatic transplantation and who subsequently (1936-2001) underwent: cardiac surgery at one institution. Data were obtained by retrospective medical record analysis. RESULTS: The study comprised 47 patients with renal (n=34) and hepatic (n=13) functioning allografts. Median time to cardiac surgery from transplantation was 79 months. The most common procedures were as follows: coronary artery bypass grafting, 22 (47%); aortic valve procedures, 11 (23%); and mitral valve procedures, 5 (11%). One patient (2%) died within 30 days of surgery Renal allograft dysfunction was noted in S renal patients (15%) Immediately after surgery. Two patients required dialysis postoperatively, 1 of whom required continued dialysis on dismissal. Transient allograft dysfunction, as determined by elevated liver enzyme levels, occurred In 6 hepatic patients (46%). However, all hepatic patients had functional allografts on dismissal. Two patients (4%) developed leg wound infections, and 9 (19%) had respiratory complications. No sternal or mediastinal infection occurred. One- and 5-year survival rates (mean ± SEM) for all patient, were 93%±4% and 76%±8%, respectively. Of the renal patients, 1- and 5-year survival rates (mean ± SEM) were 97%±3% and 82%±8%, respectively. One- and 5-year survival rates (mean ± SEM) for hepatic patients were 77%±12% and 69%±13%, respectively. CONCLUSION: Cardiac surgery can be performed safely in kidney and liver transplant recipients, with low early mortality and excellent medium-term survival. In almost all instances, allograft function is well preserved.
