Abstract Background : Cardiac allograft vasculopathy (CAV), a form of accelerated atherosclerosis, is the major cause of late death in heart transplant recipients. Routine annual coronary angiography has been used as the standard surveillance technique for CAV in most transplant centers. Hypothesis : The aim of this study was to investigate the clinical utility of routine angiographic surveillance in the detection and management of CAV in transplant recipients. Methods : We reviewed the case notes and angiograms of 230 patients who underwent cardiac transplantation in our unit between January 1986 and January 1996 and survived beyond the first year post transplantation. Results : Significant complications secondary to angiography arose in 19 patients (8.2%). Cardiac allograft vasculopathy was present on none of angiograms performed 3 weeks post transplantation, but was identified in 9 patients (4%) at the first annual angiogram and an additional 25 patients by the fifth annual angiogram. A target lesion suitable for angioplasty was only identified in two patients, and only limited procedural success was achieved in both cases. Twenty‐five patients (11%) died during the study period, and the most common cause of late death was graft failure which occurred in 10 patients. All patients who died from graft failure had significant CAV at autopsy, but the most recent coronary angiogram had been normal in eight of these patients. Conclusions : These data clearly illustrate the limited clinical utility of routine angiographic surveillance for CAV in heart transplant recipients and prompted us to abandon this method of surveillance in our unit.
