PO-02-064 REDUCED POST-ABLATION CHEST PAIN WITH ACTIVE ESOPHAGEAL COOLING

Post-ablation chest pain from pericarditis, vagal plexus thermal injury, gastroparesis, or local inflammation is a common occurrence in patients after radiofrequency (RF) catheter ablation of the left atrium for treatment atrial fibrillation (AF), with combined reported incidence 25% to 50% more. Active esophageal cooling has been have pleiotropic effects which may mitigate and reduce likelihood post-ablation pain. To quantify change adoption active during RF ablation. Data community hospital registry were obtained 12 months prior to, Type (pulmonary vein isolation, PVI, without additional posterior wall PWI, including roof lines floor lines) was recorded, along patient symptoms, type prophylactic utilized. Incidence rates before then compared. 183 reviewed. adopted December 2021. Prior that, luminal temperature (LET) monitoring multi-sensor probe utilized, all treated 2 weeks daily sucralfate pantoprazole, an 4 added case persisting symptoms. In cooling, total 90 (66.7% persistent AF) received 62 (68.9%) receiving lines, 60 (66.7%) 41 (45.6%) reporting requiring extension 6 weeks. changed days 93 (75.2% 79 (84.5%) 75 (80.6%) none (p<.0001). Adoption associated significant reduction despite increased use PWI decreased treatment.
