N2 - Introduction and objectives: Percutaneous coronary intervention (PCI) for aorto-ostial chronic total coronary occlusion (CTO) can be a particularly challenging lesion subset. The aim of this study was to analyze the technical aspects and outcomes of aorto-ostial CTO PCI in a multicenter registry. Methods: Patients undergoing aorto-ostial CTO PCI at 4 centers between February 2013 and December 2018 were included. Success rates, as well as procedural aspects and outcomes, were analyzed. Results: A total of 103 patients were included. Mean age was 64 ± 10 years and the mean J-CTO score was 3.1 ± 1.1. Thirty-one lesions (30.4%) were flush ostial CTOs. Technical and procedural success were achieved in 79 (76.7%) and 78 (75.7%) of the patients, respectively. The retrograde approach was the most frequent successful crossing technique (n = 49; 62.0%), especially in flush vs nonflush aorto-ostial CTOs (82.6% vs 53.5%; P =.02). The only variable independently associated with technical failure was the absence of interventional collaterals (OR, 12.38; 95%CI, 4.02-38.15; P <.001). Coronary perforation occurred in 4 patients (3.9%) requiring covered stent implantation (without subsequent cardiac tamponade) and 2 patients (1.9%) had a stroke (one of which was a transient ischemic attack). During a median follow-up of 31 months, 3 (2.9%) patients died from cardiovascular causes and 13 (12.6%) required repeat target vessel revascularization. Conclusions: Aorto-ostial occlusions represent a challenging subset for PCI. However, an acceptable success rate with favorable outcomes during follow-up can be achieved by experienced operators. The presence of interventional collaterals allowing the use of the retrograde approach is key for achieving procedural success.
