Transient conduction block of the superior vena cava following pulsed field ablation of the right superior pulmonary vein

Year: 2025

Type: article

Abstract: This case demonstrates that an immediate superior vena cava (SVC) conduction block may occur during pulsed field ablation (PFA) due to anatomical proximity, a positive tissue proximity index, and a narrow SVC diameter. However, lesions not directly influenced by PFA tend to regress and may be reversible, leading to SVC potential reconduction.
