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.
