New study tests better way to freeze away heart rhythm problem
NCT ID NCT05296824
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 320 adults with paroxysmal atrial fibrillation (a type of irregular heartbeat) to compare two cryoballoon ablation techniques: freezing only the pulmonary veins versus freezing both the veins and the back wall of the heart's left upper chamber. The goal was to see which method better prevents the heart rhythm problem from coming back over more than three years. Researchers reviewed past medical records from a single hospital to find the answer.
