Superior Vena Cava Stenosis after Radiofrequency Catheter Ablation for Electrical Isolation of the Superior Vena Cava

Ectopic beats originating from the superior vena cava (SVC) may initiate atrial fibrillation. This report describes a patient undergoing radiofrequency catheter ablation for electrical isolation of the SVC resulting in SVC stenosis. Noncircumferential lesion sets for SVC isolation to reduce ablation times may be preferred. (PACE 2010; e36-e38).
