New 12-step heart ablation method aims to keep irregular heartbeat away longer
NCT ID NCT06706518
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a systematic 12-step workflow for a newer type of heart ablation (pulsed-field ablation) in 118 adults with atrial fibrillation. The goal was to see if this approach could better isolate the pulmonary veins and reduce the chance of the heart rhythm problem returning. Participants had a follow-up procedure to check if the veins stayed isolated. The study focused on improving long-term results while keeping the procedure safe.
