Summary

This study compares two types of repeat catheter ablation for people with symptomatic atrial fibrillation (AF) whose first treatment didn't work. 200 participants will be randomly assigned to receive either dual-energy ablation or standard contact force-guided ablation. The goal is to see which method better restores normal heart rhythm and reduces symptoms.

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 (dual energy RF/PFA or contact force-guided RF)
What this could lead to
If successful, this could show which repeat ablation method is more effective for controlling atrial fibrillation symptoms.
What could go wrong
This is a small pilot study, so results may not apply to everyone. There are risks from the procedure itself, like bleeding or heart damage.
