DIRECT PULMONARY VEIN ABLATION WITHOUT STENOSIS: CHRONIC EFFICACY OF A NOVEL ELECTROPORATION TECHNIQUE

Despite the primary trigger for atrial fibrillation (AF) being within the pulmonary vein, current treatments avoid direct ablation of this substrate because of the prohibitive incidence of pulmonary vein (PV) stenosis. Given the suboptimal results with contemporary thermal AF ablation, we previously
