Heart MRI checks how well ablation lesions form
Part of Heart & circulation clinical trials.
This study uses a special heart MRI to look at how ablation creates scar tissue in people with atrial fibrillation. It may help doctors improve how ablation is done and understand which technique works best.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older
- You have atrial fibrillation that is either persistent or comes and goes (paroxysmal)
- You are planning a catheter ablation using radiofrequency, cryo (very cold), or pulsed field energy
- You do not have a known or suspected allergy to gadolinium dye used in some MRIs
- You can safely have an MRI (for example, not severely claustrophobic and no MRI-blocking implants/devices)
- You have not had prior treatment in the left atrium (no prior ablation or surgery)
Quick eligibility check
Answer a few plain-language questions, based on this study's own requirements, to get a preliminary sense of fit.

Other trials that look related to this one.
This study uses high-resolution MRI scans to get a detailed picture of the heart before a special type of ablation for atrial fibrillation (an irregular heartbeat). The goal is to help doctors target the treatment more precisely.
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 study uses an MRI scan before heart surgery to look for heart scarring that may predict who will develop atrial fibrillation afterward. Knowing the risk ahead of time could help doctors monitor you more closely and plan prevention.
This trial checks whether a specific MRI-safe 12-lead heart recording (ECG) works correctly during MRI scans. It may help improve how doctors monitor heart rhythm while imaging, especially for people with atrial fibrillation.
This study looks at blood-related “clotting” signs and heart scan results in people with atrial fibrillation (AF) who are getting a catheter ablation. It may help doctors better understand AF and choose treatments more precisely.
This study compares two ways to create small burns in the heart tissue to fix an irregular heartbeat (atrial fibrillation). It uses a special MRI to see how well each method works.
