CT scan study of pulse-field ablation for AF
Part of Heart & circulation clinical trials.
This study compares CT scans taken before and 3 months after atrial fibrillation ablation to see how pulse-field ablation affects lung tissue compared to radiofrequency. If you had AF ablation between 2020 and 2024 with the specified techniques and have the required CT scans, you may be able to help doctors understand long-term effects.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years of age or older.
- You had atrial fibrillation (AF) ablation using either pulse-field ablation (FARAPULSE) or radiofrequency, performed between 2020 and 2024.
- You have either paroxysmal (comes and goes) or non-paroxysmal (persistent) AF.
- You have high-quality CT scans from before your ablation and about 3 months after (plus or minus 2 weeks).
- You did not receive ethanol (alcohol) injection into the vein of Marshall as part of your treatment.

This study is for people with atrial fibrillation who are planning to have a catheter ablation procedure. It will look at how well the heart works after the procedure and how to prevent future events.
This trial tests a newer ablation technique called pulsed field ablation to treat atrial fibrillation, a heart rhythm disorder. The goal is to see if this method works well and is safe for patients who need treatment.
This trial tests two different ablation techniques to treat a type of irregular heartbeat that doesn't go away on its own. It aims to find which approach works better and is safer.
This trial tests two different catheters that use pulsed field energy to treat atrial fibrillation (a heart rhythm problem). It aims to find which one works better for people who need blood thinners but have a high risk of bleeding.
This study tests a way to perform catheter ablation for atrial fibrillation using a non-fluoroscopic lab, meaning no x-ray is needed during the procedure. It may help patients avoid radiation exposure.
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.
