TCT-101 Percutaneous Coronary Intervention of Aorto-Ostial Coronary Chronic Total Occlusion: Results and Technical Implications From a Multicenter Registry

Procedural success was defined as technical success plus the absence of in-hospital adverse events (all-cause death, Q-wave myocardial infarction, stroke, recurrent angina requiring target-vessel revascularization with PCI or coronary artery bypass graft, tamponade requiring pericardiocentesis or surgery). Major adverse cardiac events (MACE) on follow-up were defined as a composite of cardiac death, myocardial infarction, and clinically driven target lesion revascularization.Results A total of 102 patients were included. Regarding in-hospital complications, 6 (5.9%) patients experienced a non–Q-wave periprocedural myocardial infarction, 4 (3.9%) presented contrast-induced nephropathy, and 4 (3.9%) patients had a target CTO vessel perforation requiring covered stent implantation.
