Abstract

BACKGROUND: The use of retrograde crossings in chronic total occlusion (CTO) percutaneous coronary intervention (PCI) provides higher technical success rates in CTO-PCI. However, the use of epicardial collaterals carries a higher complication risk.

METHODS AND RESULTS: In this study, we aimed to investigate the temporal trends in retrograde crossing of epicardial collaterals, introduction of new guidewires, in-hospital major adverse cardiovascular events (MACE), and technical success rates in a large, multinational registry. We demonstrate that technical success rates increased substantially from about 5%-10% to 76% in the past decade without a concomitant increase in MACE rate (~3% to 4%), likely associated with increased operator experience and introduction of new guidewires. In addition, we show that while high-volume centers have higher technical success, they also have higher perforation rates.
