Pulsed field ablation of a persistent left superior vena cava triggering atrial fibrillation: A case report
We report the case of a 55-year-old Caucasian male undergoing a third catheter ablation procedure for atrial fibrillation (AF). During the intervention, a previously undiagnosed persistent left superior vena cava (LSVC) appeared to contribute to the maintenance of AF. Given its anatomical characteristics, electrical isolation of the LSVC was performed using pulsed field ablation (PFA) rather than conventional radiofrequency (RF) ablation. Pulsed field ablation seems to be a novel, effective, and safe tool, particularly for targeting larger anatomical structures.
