Methods: Procedural characteristics and long-term overall survival were assessed in 679 consecutive "all-comer" patients, who underwent PCI in at least two main vessels. We adapted three definitions of CR from the coronary artery bypass grafting (CABG) trials. CR was achieved if following MV-PCI one of the three criteria was met: (1) no residual stenosis in a main coronary vessel, (2) no residual stenosis in any coronary segment, or (3) no residual stenosis in the left anterior descending (LAD) and at least one further main branch. The main objective was the evaluation of predictors of incomplete revascularization and the prognostic impact of CR in MV-PCI patients. Results: CR was achieved in 76%, 67%, and 95%, respectively, (definitions 1-3). Patients without CR were older, had a lower ejection fraction, and presented more often with acute coronary syndromes (ACS). Clinical long-term follow-up regarding survival was available in 664 patients (98%) with a mean follow-up of 2.5 +/- 1.6 years. Independent of the specific definition, CR was associated with a reduced long-term mortality by approximately 50%. After adjusting for relevant baseline parameters, only absence of residual stenosis in all coronary segments remained as an independent predictor of long-term prognosis (hazard ratio [HR] = 0.51, 95% confidence interval [CI]: 0.28-0.93; P = 0.025). Conclusions: CR of all coronary segments is associated with improved overall survival after MV-PCI. (J Interven Cardiol 2010;23:256-263).
