New heart mapping method could cut repeat ablations
NCT ID NCT05239364
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compares two approaches for treating atrial tachycardia that occurs after atrial fibrillation ablation or heart surgery. One group gets standard ablation targeting all abnormal heart circuits, while the other gets a more focused ablation guided by a new ultra-high-density mapping system. The goal is to see if the targeted approach reduces the chance of arrhythmia coming back. About 100 adults who have had prior AF ablation or heart surgery and now have a stable atrial tachycardia will take part.
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 (radiofrequency)
What this could lead to
If successful, this approach could reduce the number of repeat procedures needed for atrial tachycardia after atrial fibrillation treatment or heart surgery.
What could go wrong
This is an early-stage study with 100 participants, so results may not apply to all patients. The procedure carries standard risks of catheter ablation, such as bleeding or heart tissue damage.
