Long-Term Outcomes of Chronic Total Occlusion Percutaneous Coronary Intervention Among Medicare Beneficiaries.

ABSTRACT:

Background

Chronic total occlusion (CTO) percutaneous coronary interventions (PCIs) represent 4% of all PCIs for stable angina in the United States and have been associated with lower success and higher in-hospital event rates compared with non-CTO PCIs. We aimed to examine long-term outcomes of CTO PCI compared with non-CTO PCI, including prespecified subgroups of high-risk non-CTO PCI (atherectomy/saphenous vein graft/unprotected left main).

Methods

Among 551,722 patients in the National Cardiovascular Data Registry CathPCI Registry linked to Medicare (July 2009-December 2016), we evaluated in-hospital events and long-term major adverse cardiovascular events of CTO PCIs (N = 29,407) compared with non-CTO PCIs (N = 522,315). We then evaluated similar outcomes between CTO PC
