New catheter combo aims to keep AFib in check longer
NCT ID NCT03963349
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how well a special catheter (THERMOCOOL SMARTTOUCH SF) and software (Ablation Index) work to treat paroxysmal atrial fibrillation, a type of irregular heartbeat. Researchers will track 150 adults who get this procedure to see if they stay free of heart rhythm problems for up to a year. The goal is to improve the safety and long-term success of the ablation procedure.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
radiofrequency ablation using THERMOCOOL SMARTTOUCH SF catheter with Ablation Index software
What this could lead to
If successful, this could confirm that using this specific catheter and software improves long-term control of atrial fibrillation with fewer repeat procedures.
What could go wrong
This is a single-center, real-world study with only 150 participants, so results may not apply to all patients. The procedure carries standard risks like bleeding, infection, or heart rhythm changes.
