Successful abdominal aortic aneurysm resection in long-term survivors of cardiac transplantation.

With the improvement of survival rates following cardiac transplantation, the probability of recipients developing extracardiac disease is increased. Three cases are reported of abdominal aortic aneurysm successfully operated on in cardiac allograft recipients 1 to 4 years after transplantation. Indications for transplantation were valvular, idiopathic and ischaemic cardiomyopathy. Post-transplant hypertension and hyperlipidaemia may have played a role in the rapid growth of the aneurysms. Cardiac function and the incidence of graft atherosclerosis were assessed before surgery by coronary angiography. All three patients were discharged from hospital. Abdominal aortic aneurysm resection may be a safe procedure in cardiac transplant patients. In view of the rapid increase in the size of the aneurysms in transplanted patients, careful screening should be performed during follow-up.
