Chronic total occlusion procedure registry

This study is a registry that collects information from people who are having a procedure to open a completely blocked heart artery. It helps doctors learn more about these procedures and how to improve care for people like you.

This study looks at people with a long-standing complete blockage in a heart artery. The goal is to understand risk factors and outcomes, which may help guide future treatments.

This trial studies a special heart procedure (CTO-PCI) to open a blocked coronary artery in people with heart failure and ongoing symptoms. It may help improve blood flow to the heart and symptoms for carefully selected patients.

This study looks at the long-term (10-year) outcomes of a specific stenting technique for patients with a chronic total occlusion (a complete blockage that has been there for at least 3 months) in a major heart artery. It aims to see how well the procedure works over time.

This trial tests whether a special balloon coated with medicine (drug-coated balloon) can safely open a completely blocked heart artery, instead of using a permanent stent. It may be an option for people who have chronic chest pain or shortness of breath due to a long-standing blockage.

This trial tests two procedures—antegrade dissection/re-entry and the retrograde method—to treat a completely blocked artery. It compares which technique works better for patients with complex blockages.
