Ca-534-03 investigating pulsed field (pfa) vs radiofrequency ablation (rfa) lesion characteristics in an in vivo healthy porcine left ventricle (lv) using 3d lge and native t1w magnetic resonance imaging (mri)

PFA is an emerging largely non-thermal method of ablation. Recently, it was shown in an in vivo porcine model that increasing the number of trains resulted in larger PFA lesions1. However, it remains unclear how PFA lesions mature over time.
