Why the study?
While paroxysmal atrial fibrillation most commonly originates in pulmonary veins, the superior vena cava can be arrhythmogenic, and pulsed field ablation is an emerging selective ablation technology.
Does pulsed field ablation at the superior vena cava terminate recurrent paroxysmal atrial fibrillation?
Does pulsed field ablation at the superior vena cava terminate recurrent paroxysmal atrial fibrillation?
Pulsed field ablation of the superior vena cava can successfully terminate recurrent paroxysmal atrial fibrillation driven by non-pulmonary vein triggers.
Supports PFA feasibility for SVC isolation in recurrent AF; leaves open confirmation of safety and efficacy.
Paroxysmal atrial fibrillation originates most commonly in the pulmonary veins. However, the superior vena cava has proved to be arrhythmogenic in some cases. Pulsed field ablation, an emerging ablation technology, selectively affects myocardial tissue. Herein, we present a case of paroxysmal atrial fibrillation in a 64-year-old man who was admitted to our hospital for pulsed field ablation. The tachycardia was recurrent despite four successful pulmonary vein isolations. The superior vena cava was determined to be involved in arrhythmogenesis. The atrial fibrillation terminated immediately after the pulsed field ablation discharge at the superior vena cava.
