Patient Registry of Percutaneous Coronary Intervention (PCI) for Chronic Total Occlusion (CTO) by Japanese Experts

What this Trial Is About

Researchers are collecting information on the treatment of chronic total occlusion (CTO) in coronary arteries using percutaneous coronary intervention (PCI). This registry aims to develop a consensus on the best treatment strategies by observing procedures performed by certified Japanese operators. The study is observational and focuses on real-world outcomes of PCI for CTO. The study involves patients who have undergone PCI for CTO lesions in major coronary artery segments or large branches, with occlusions lasting more than three months or of unknown duration. There is no experimental treatment; instead, the registry gathers details about the PCI procedures performed by experts. Patients are followed to assess outcomes after the intervention. Participants will be monitored for successful reopening of blocked arteries without major heart or brain complications shortly after PCI and over a five-year period. The main outcome measured is the absence of major adverse cardiocerebral events during early and long-term follow-ups. The study began in 2013 and will continue through December 2027, with no specific maximum age limit for participants.
