Beyond the Pulmonary Veins: The Influence of Pulsed Field Ablation on the Superior Vena Cava.

ABSTRACT:

Background

Pulsed field ablation (PFA) selectively ablates myocardial tissue while minimizing damage to surrounding structures. However, its effects on the superior vena cava (SVC) during right superior pulmonary vein (RSPV) isolation remain unclear.

Objective

This study aimed to assess the impact of PFA on the SVC and determine whether anatomical proximity contributes to conduction delay or isolation.

Methods

This prospective, single-center observational study analyzed 15 patients with paroxysmal atrial fibrillation (AF) who underwent PFA at our institution between December 2024 and February 2025. A 12-F multipolar PFA catheter (FARAWAVE) was used. The shortest RSPV-SVC distance was measured using preprocedural contrast-enhanced CT and intraprocedural electroanatomic
