%X Background. Benefits of cardiac screening in kidney transplant candidates (KTC) will be dependent on the availability of effective interventions. We retrospectively evaluated characteristics and outcome of percutaneous coronary interventions (PCI) in KTC selected for revascularization by a cardiac screening approach. Methods. In 267 patients evaluated 2003 to 2006, screening tests performed were reviewed and PCI characteristics correlated with major adverse cardiovascular events (MACE) during a follow-up of 55 months. Results. Stress tests in 154 patients showed ischemia in 28 patients (89% high risk). Of 58 patients with coronary angiography, 38 had significant stenoses and 18 cardiac interventions (6.7% of all). 29 coronary lesions in 17/18 patients were treated by PCI. Angiographic success rate was 93.1%, but procedural success rate was only 86.2%. Long lesions ( ) and diffuse disease ( ) were associated with MACE. In high risk patients, cardiac screening did not improve outcome as 21.7% of patients with versus 15.5% of patients without properly performed cardiac screening had MACE ( ). Conclusion. The moderate procedural success of PCI and poor outcome in long and diffuse coronary lesions underscore the need to define appropriate revascularization strategies in KTC, which will be a prerequisite for cardiac screening to improve outcome in these high-risk patients. 1. Introduction In recent years, many end stage renal disease (ESRD) patients with advanced age or significant cardiovascular disease are accepted on the growing waiting lists because of the survival benefit kidney transplantation may confer even to high risk patients [1¨C6]. As kidney transplant candidates frequently have severe coronary artery disease (CAD) and a high cardiovascular mortality, invasive or noninvasive screening for CAD and revascularization in case of significant myocardial ischemia have long been recommended [7¨C10]. However, since randomized controlled studies in nonrenal populations showed no benefit of preoperative revascularization [11, 12], nowadays revascularization is recommended only in patients with high risk coronary lesions and significant symptoms and/or ischemia [13]. Furthermore, current guidelines in the general population recommend basing revascularization strategies in complex CAD on coronary lesion characteristics, since the SYNTAX trial demonstrated that complex coronary lesions were associated with worse outcome of PCI compared to coronary artery bypass grafting (CABG) [13, 14]. In ESRD patients, however, little is known about the optimal strategy in
