NCT ID NCT03737929
First seen Jun 15, 2026 · Last updated Jun 23, 2026 · Updated 2 times
Summary
This study aimed to see if combining surgical and catheter ablation (hybrid therapy) works better than standard catheter ablation alone for people with persistent atrial fibrillation. The trial was terminated after enrolling only 7 participants, so no meaningful conclusions can be drawn. The approach remains experimental and unproven.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Hybrid ablation (surgical epicardial ablation combined with percutaneous catheter ablation)
What this could lead to
If it had succeeded, this approach could have offered a more effective treatment for persistent atrial fibrillation, potentially reducing recurrence and the need for repeat procedures.
What could go wrong
The trial was terminated early with only 7 participants, so results are not reliable. Hybrid ablation also carries higher complication risks than catheter ablation alone.
