B-PO01-076 FEASIBILITY OF LOCAL IMPEDANCE MONITORING IN ATRIAL FIBRILLATION ABLATION WITH HIGH POWER SHORT DURATION LESIONS

      High power short duration (HPSD) ablation may improve pulmonary vein isolation (PVI) durability and shorten radiofrequency ablation (RFA) time. Measurement of local impedance (LI) drop on ablation using the DIRECTSENSE software module, an advanced feature of RHYTHMIA mapping system has shown to assess acute lesion durability but has not been clinically studied with HPSD.
