Objectives This study was performed to evaluate the acute outcomes of percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) based on operator experience. Background Despite developments in both technology and techniques, PCI procedures for CTO's remain challenging. Methods A total of 3,229 eligible subjects who underwent CTO‐PCI were enrolled from 56 centers by a retrograde summit using a web registry system. To compare the acute outcomes of the CTO data, 18 centers were classified as higher volume centers (HC) and 38 centers as lower volume centers (LC) depending on the CTO‐PCI experience of the operator. Results The mean procedural success rate of all centers was 88.4%. The overall procedural success rate was significantly higher in HC than LC (90.6% vs. 85.6%, respectively; P < 0.0001). In addition, overall antegrade success rate was also higher in HC than LC (91.0% vs. 83.9%, respectively; P < 0.0001). Although the overall retrograde approach success rate was significantly higher in HC than LC (85.0% vs. 77.6%, respectively; P < 0.0001), there was no significant difference in that of the retrograde alone (89.0% vs. 93.7%, respectively; P = 0.051). Major in‐hospital adverse events were observed in 0.53% of cases, and the rates were similar between the two groups (0.45% vs. 0.62%, respectively; P = 0.25). Conclusions Although CTO‐PCI was safe in both groups, the procedural success rate was significantly higher in HC than LC, even in this new era of CTO‐PCI. This difference was attributed to the difference in the antegrade procedural success rate. © 2015 Wiley Periodicals, Inc.
