New Imaging-Guided ablation aims to stop stubborn AFib

NCT ID NCT02184013

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This pilot study tests whether using advanced imaging (ECGI, MRI, and PET scans) to identify abnormal heart tissue and electrical circuits can improve catheter ablation for persistent atrial fibrillation. Fifty-two adults with persistent AF who have not had prior ablation will receive a tailored procedure. The main goal is to see if this approach can stop AF during the procedure and reduce recurrence afterward.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

catheter ablation guided by ECGI mapping and atrial fibrosis mapping (DE-MRI)

What this could lead to

If successful, this approach could improve success rates for catheter ablation in patients with persistent atrial fibrillation, reducing recurrence.

What could go wrong

This is a small pilot study (52 participants) with no control group, so results may not be generalizable. The procedure carries standard risks of catheter ablation, such as bleeding or heart damage.
