Abstract
AbstractWe report a case of atrial fibrillation (AF) recurrence after pulmonary vein isolation, which patient had AF trigger in the superior vena cava (SVC) near the sinus node (SN). The ultra‐high‐resolution mapping revealed that SN located within the SVC and the atrial activation from the SN to SVC propagated in both septal and lateral direction, then upward with circumventing the spontaneous conduction block identified just above and lateral SN (upper hemisphere). We successfully isolated SVC including the ectopic origin at the same level as the SN by utilizing the spontaneous conduction block line around the SN without any complication.
