Key result
Thoracoscopic ablation successfully restored sinus rhythm in a patient with atrial fibrillation and persistent left superior vena cava, with no major adverse events at 12 months.
Why the study?
Persistent left superior vena cava can initiate and maintain AF, but most publications report radiofrequency catheter ablation rather than thoracoscopic approaches.

Thoracoscopic ablation with preprocedural virtual reality simulation is a feasible and safe surgical option for patients with atrial fibrillation and persistent left superior vena cava.
Single-case success supports VR-assisted thoracoscopic ablation in AF with PLSVC; leaves open prospective validation before wider use.
Persistent left superior vena cava (PLSVC) is a relatively rare congenital anomaly in the general population. It plays an important role in initiating and maintaining atrial fibrillation (AF) in some patients. Radiofrequency catheter ablation is the major treatment for patients with AF and PLSVC in most publications. Here, we reported a case of thoracoscopic ablation for a patient with atrial fibrillation and persistent left superior vena cava. After preprocedural simulation using virtual reality, we successfully completed box-lesion, ablation line from superior vena cava to inferior vena cava, left atrial appendage (LAA) excision, and PLSVC ablation. It provides a new perspective on surgical treatment for patients with AF and PLSVC.

Liu et al. (2023) conducted a case report in Atrial fibrillation and persistent left superior vena cava (n=1). Thoracoscopic ablation was evaluated on Restoration of sinus rhythm and absence of major adverse events. Thoracoscopic ablation successfully restored sinus rhythm in a patient with atrial fibrillation and persistent left superior vena cava, with no major adverse events at 12 months.
