Bigger balloon, better burn? new study maps heart lesions
NCT ID NCT05881733
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a larger 31 mm cryoballoon in 20 patients with paroxysmal atrial fibrillation to see how much heart tissue it could freeze. Researchers used 3D maps before and after the procedure to measure the size of the treated area. The goal was to gather data to improve future ablation procedures, not to directly treat the condition.
