Key result
Superior vena cava isolation by a single radiofrequency application eliminated the remaining far-field potential in the right superior pulmonary vein during catheter ablation.
Case Report (n=1)
This case demonstrates that superior vena cava isolation can be identified by the disappearance of far-field SVC potentials recorded in the right superior pulmonary vein during ablation.

May aid confirmation of SVC isolation via RSPV signals during ablation; hypothesis-generating and requires validation in prospective cohorts.
Yagishita et al. (2013) conducted a case report in Paroxysmal atrial fibrillation (n=1). Catheter ablation (right superior pulmonary vein and superior vena cava isolation) was evaluated. Superior vena cava isolation by a single radiofrequency application eliminated the remaining far-field potential in the right superior pulmonary vein during catheter ablation.
