U.S., Aug. 9 -- ClinicalTrials.gov registry received information related to the study (NCT07112716) titled 'SVC-isolation in Redo-AF Ablation With Isolated PV' on Aug. 02.
Brief Summary: Atrial fibrillation is the most common arrhythmia in the population and is often caused by arrhythmogenic foci located in the pulmonary veins. For this reason, the first attempt in atrial fibrillation catheter ablation procedures is to isolate these structures (the procedure is called indeed "pulmonary vein isolation"), which results in abolishment of arrhythmia recurrence in up to 85% of patients at short and mid-term follow-up. However, a subset of patients experience an atrial tachyarrhytmia recurrence and a second catheter ablation procedure has to be ...
