Pulsed-Field Ablation Circular Catheter Use in Left Superior Vena Cava-Associated Atrial Arrhythmias.

ABSTRACT:

Background

This case presented the first domestic instance of ablation for persistent left superior vena cava (PLSVC)-associated atrial arrhythmia, utilizing the "Varipulse" pulsed-field ablation system.

Case summary

The computed tomography angiography examination revealed the presence of a PLSVC. During the procedure, left atrial modeling was performed using the CARTO^3D electroanatomical mapping system, and models of the pulmonary veins and PLSVC were manually constructed in conjunction with intracardiac echocardiography. A combined ablation strategy was employed intraoperatively, and after pulsed-field ablation of the earliest activation site in the middle segment of the PLSVC, the patient's rhythm converted to sinus.

Discussion
