Characterization of <i>In Vitro</i> and <i>In Vivo</i> Lesions Made by a Novel Multichannel Ablation Generator and a Circumlinear Decapolar Ablation Catheter

Abstract

Temperature-controlled, power-limited RF energy with the PVAC is feasible for creating circumferential transmural lesions (SVC) that sometimes extended to neighboring structures. Lesion depth can be titrated by varying the bipolar:unipolar energy ratio. This novel ablation system paves the way for single-catheter ablation of AF.
