Ischemia Miocardica Ritardata Letale, Aritmie Ventricolari e SCD dopo PFA di AF: Serie di Casi Estesa.

BACKGROUND: Pulsed field ablation (PFA) is an increasingly used energy source to treat patients with atrial fibrillation (AF). Although nonthermal ablation seems to result in a safety benefit, adverse events occurring after PFA are not well studied. OBJECTIVES: The aim of this study was to report life-threatening ischemic and arrhythmic adverse events (AEs) occurring after PFA of AF. METHODS: A case series and systematic literature review were conducted, including patients with AF who experienced ischemic AEs with delayed onset or arrhythmic AEs after PFA energy delivery between March 2023 and January 2026. Events were classified as 1) delayed and/or recurrent ST-segment elevation; 2) vent
