Ablation catheter orientation: In vitro effects on lesion size and in vivo analysis during PVI for atrial fibrillation

Abstract

In an in vitro setting, catheter orientation affects SLL and AML, but not LD and SLW. During PVI procedures, catheter orientation resulted mostly parallel to the endocardium. Catheter orientation varied among different WACA segments, but only small differences were found between three operators when considering similar WACA segments.
