Pulsed-field ablation for atrial fibrillation and heart function on MRI
Part of Heart & circulation clinical trials.
This study looks at whether a newer type of heart ablation (pulsed-field ablation) that also treats the back wall of the heart helps heart function better than just the standard vein isolation. If you are having this ablation, the study will use MRI scans to check your heart's pumping and relaxation before and after the procedure.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You have a type of irregular heartbeat called atrial fibrillation (either episodes that come and go or that last a long time), and your doctor has recommended a catheter ablation procedure.
- You plan to have a specific type of ablation that uses pulsed-field energy and includes isolating the back wall of your heart's left upper chamber.
- Your atrial fibrillation was confirmed on an ECG within the last 12 months.
- You are able to have an MRI and do not have certain metal implants, a pacemaker, severe kidney disease, or severe claustrophobia.
- You have not had a previous ablation in the left atrium, previous heart surgery, or significant heart valve problems.

This study tests if a new type of energy called pulse field ablation (a procedure that uses short bursts of electric pulses) works as well as standard ablation for restoring normal heart rhythm in patients with episodes of irregular heartbeat. It may help your heart pump more normally.
This study looks at how a new type of heart procedure, called pulsed field ablation, affects the heart's structure in people with persistent atrial fibrillation. It may help doctors understand if this treatment improves heart function over time.
This study tests a new heart procedure using pulsed field ablation (a type of energy to fix irregular heartbeats) for people who have had atrial fibrillation for less than a year. It may help restore a normal heart rhythm and reduce symptoms.
This study tests a new way to do a heart procedure (catheter ablation) for people with ongoing atrial fibrillation (an irregular heartbeat). It uses pulsed-field energy to create a block in the heart that stops abnormal electrical signals. The goal is to improve the procedure's success and reduce risks.
This study tests a newer, gentler way to fix irregular heartbeats in people with paroxysmal AF. The treatment uses special energy (pulsed fields) guided by 3D imaging to target the heart tissue causing the problem, and the goal is to restore a normal rhythm with fewer risks.
This study compares two ways of using a new type of energy called pulsed field ablation to treat atrial fibrillation. The goal is to see if using a special heart map to guide the treatment works better than the standard approach. If you have intermittent irregular heartbeats from AF, this trial might help improve your care.
