NCT ID NCT07298473
First seen Jan 04, 2026 · Last updated Apr 25, 2026 · Updated 19 times
Summary
This study tests a new catheter system (Sphere-9 and Affera) for a repeat heart ablation procedure in 400 people whose atrial fibrillation (AFib) came back after a first ablation. Participants will have the procedure and be followed for 12 months to see if it safely restores normal heart rhythm without needing more treatments. The goal is to improve long-term control of AFib symptoms.
