Long‐Term Outcome of Catheter Ablation in Patients with Atrial Fibrillation Originating from the Superior Vena Cava

Abstract

Among the patients with paroxysmal AF originating from the SVC, 73% remained free of AF for 5 years after a single catheter ablation procedure. Superior vena cava isolation without PV isolation is an acceptable therapeutic strategy in those patients with AF originating from the SVC only. The SVC diameter was an independent predictor of AF recurrence. (J Cardiovasc Electrophysiol, Vol. 23, pp. 955-961, September 2012).
