Chronic total occlusion procedure registry

This study collects data from people who have a completely blocked heart artery and are having a procedure to try to open it. The information will help 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 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 opening completely blocked heart arteries with a stent (angioplasty) helps people with heart failure and chest pain or shortness of breath. It aims to see if this procedure improves how well the heart works and reduces symptoms.

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.
