Allograft vascular disease is a significant cause of death of cardiac transplant recipients after the first year of transplantation. With few exceptions, angina pectoris does not develop and objective examinations, including coronary angiography, are necessary to diagnose coronary arteriopathy. Between 1983 and 1994, 214 heart transplantations in 211 patients were performed in our unit. All survivors had coronary angiography performed yearly. Thirty patients had significant localized arterial stenoses. Twelve patients with critical stenosis were accepted for percutaneous transluminal coronary angioplasty. Five patients underwent retransplantation due to progressive graft vascular disease with development of congestive heart failure. Conventional revascularization with transluminal coronary angioplasty can safely be performed with primary good results. In selected patients, retransplantation is an option if patients otherwise fulfil standard criteria for cardiac transplantation.
Pulmonary arteriovenous fistula wherein the malformation has venous drainage directly to the left atrium is a rare anomaly. Two case reports present such unusual arteriovenous malformations successfully treated by surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
