Brief Summary:
Redo procedures after CLOSE-guided pulmonary vein isolation (PVI) for atrial fibrillation (AF) occur in 10% of patients. In case of pulmonary vein (PV) reconnection, electrophysiologists may re-isolate the pulmonary veins with or without the ablation of other commonly known PV-triggers. The superior vena cava (SVC) is one of the most common non PV-triggers for atrial tachyarrhythmias. SVC electrical isolation can be reached by circular radiofrequency-ablation under close monitoring of the phrenic nerve. However, it's added value remains unclear.
With this prospective, randomized, controlled, unblinded, mono-center study, the investigators aim to evaluate the 1-year recurrence rate in paroxysmal AF patients with reconnected pulmonary veins during a redo ablation with PV re-isolation or PV re-isolation with SVC isolation.
