CT scan study for complex blocked heart artery procedures
Part of Heart & circulation clinical trials.
This trial studies how a CT scan may help plan a procedure to open a long-standing blocked coronary artery (a chronic total occlusion). It is aimed at people with complex, difficult blockages and symptoms or heart test results showing parts of the heart may still be alive.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 90 years old
- Your body mass index (BMI) is 40 or less
- You agree to join and sign the consent form before any study steps
- You have a long-term blocked coronary artery (TIMI 0 flow for over 3 months) and signs of heart muscle that may still be viable, plus symptoms or testing showing reduced blood flow (angina, shortness of breath, or low ejection fraction under 50%)
- Your coronary angiography score shows a complex blockage (J-CTO score 2 or higher)
- You can have a study CT scan that is not already being done as standard care for diagnosis

This trial studies a heart CT scan technique to help doctors better understand coronary artery blockages. It may help guide treatment choices for people with angina (chest pain) who are at intermediate to high risk.
This trial is testing whether a special heart CT scan (coronary CT angiography) can help doctors better understand and treat calcium buildup in your heart arteries. If you have a type of heart disease that might need a stent or other procedure, this study could help decide the best approach.
This trial studies whether opening a blocked coronary artery (a CTO) helps people more than staying on the best available heart medicines after an initial 3-month treatment period. It uses heart imaging to confirm there is reduced blood flow in the area supplied by the blockage.
This study looks at whether calcium buildup seen on a heart CT scan affects the success of opening a completely blocked artery. It may help guide future treatment for people with similar blockages.
This trial looks at people with a blockage in a heart artery of 50% or more. It tests a new way to check the blockage using a special CT scan. This could help decide the best treatment to prevent future heart problems.
This study tests a new way to use CT scans to look at both the structure of your heart arteries and how well blood flows through them. It may help doctors get a more complete picture of coronary artery disease without extra procedures.
