Mid-term results of heart transplantation for end-stage valvular disease.

Abstract

The results of heart transplantation in a consecutive series of 19 end-stage valvular disease patients (15 male, aged 48 +/- 8 years) were analysed retrospectively. The indication for heart transplantation was heart failure due to left and/or right ventricular dysfunction; 16 patients had undergone previous valve surgery, but prosthetic dysfunction was present in only one patient. All patients were in NYHA class IV, 15 were on oral anticoagulants and 5 on i.v. catecholamine support. There were four in-hospital deaths (21%) and one late death (5%), resulting in a 1-year mortality rate slightly, but not significantly, higher than that of patients transplanted for other indications (16%). Mean follow-up of the survivors was 48 +/- 33 months (range 9-95); 5-year actuarial survival was similar to that observed among the other heart transplantation patients (74 +/- 10% vs 77 +/- 3%, P = NS). The incidence of acute rejection and infection was also similar in valvular disease and non-valvular disease patients. Kidney and liver function at 1 year post-heart transplantation was preserved in all cases; cardiac catheterization revealed normal graft function in all patients and the absence of coronary lesions in all but two. In conclusion, in our limited experience morbidity and mortality in patients transplanted for end-stage valvular disease seem to be similar to those of patients undergoing heart transplantation for other etiologies.
