Abstract

Abstract: We present a case of redo atrial fibrillation (AF) ablation for pulmonary vein reconnection. In mapping of posterior wall of left upper pulmonary vein (LUPV) with HD grid, a new and unique multipolar mapping catheter, it demonstrated presence of local electrocardiogram signals (EGM). But during mapping with the Tacticath ablation catheter, these signals were not visible. Nevertheless, ablation at this point resulted in isolation of LUPV. The unique mapping technology offered by HD grid mapping catheter may enable us to discover local EGM not otherwise visible in conventional bipole parallel recordings, to have more accurate maps and deliver for effective therapies.
