NCT ID NCT04109053
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study was designed to see if a new, ultra-sensitive mapping technique could better confirm that cryoballoon ablation successfully isolated the pulmonary veins in patients with paroxysmal atrial fibrillation. The trial was withdrawn before enrolling any participants, so no results are available.
