PO-03-121 INITIAL PRECLINICAL ASSESSMENT OF LEFT ATRIAL ANATOMY IMAGING USING KODEX MAPPING SYSTEM WITH ULTRA-LOW TEMPERATURE CRYOABLATION AND PULSED FIELD CRYOABLATION CATHETERS: IMPLICATIONS FOR PROCEDURAL FLOW AND COSTS OF LEFT ATRIAL ABLATION PROCEDURES

New emerging mapping and ablation technologies are examined to improve acute success of ablations, while minimizing procedure time cost. Both ultra-low temperature cryoablation (ULTC) pulsed field (PFCA) ablations shown create durable transmural lesions using mapping-capable catheters similar design, except for size, number spacing electrodes. The accuracy efficiency left atrium (LA) with a novel wide-band dielectric system (Kodex™, Philips, Inc) multielectrode capable delivering ULTC or PFCA is unknown. goal was test the anatomic rendering LA by Kodex catheter (iCLAS™, Adagio Medical) (Cryopulse™, compared map created decapolar circular (CMC, Lasso™, Biosense Webster) pre-ablation maps were obtained CMC, in swine.
