CT vs. X-ray for sizing heart device in AF treatment
Part of Heart & circulation clinical trials.
This study tests whether using a CT scan or a special X-ray (DSA) is better for picking the right size of a left atrial appendage closure device during a combined ablation and closure procedure. It aims to make the procedure safer and more effective.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You have non-valvular atrial fibrillation (not caused by a heart valve problem).
- You are scheduled to have both atrial fibrillation ablation and a left atrial appendage closure procedure.
- You can have a CT scan (no allergy to contrast dye).
- You do not have a blood clot in your left atrium or left atrial appendage.

This trial uses a special CT scan to measure how much extra fluid is in your heart muscle. It aims to help doctors better understand and treat your atrial fibrillation before you have a procedure called ablation.
This study looks at long-term outcomes after LAA closure (a procedure to reduce stroke risk) by reviewing CT scans of the device. It aims to learn if blood flow around the device affects healing and future health.
This study looks at how different imaging tests can help guide a procedure that closes off the left atrial appendage to reduce stroke risk. It may help doctors choose the safest approach during the procedure.
This trial studies whether CT scans and heart MRI scans (done around the time of atrial fibrillation ablation) can help care planning and results. It may help your team better understand your heart before and after the procedure.
This trial tests a new imaging method (4D-ICE) used alongside a standard ultrasound (TEE) during a heart procedure to close the left atrial appendage, a small pouch in the heart where clots can form in people with atrial fibrillation. The goal is to see if the new method makes the procedure safer and more precise.
This trial is testing whether a coronary CT angiography scan, performed before catheter ablation for atrial fibrillation, helps doctors find hidden blockages in heart arteries. It may help people without known heart disease avoid unnecessary procedures.
