Abstract:
Objective:To compare the effects of high-power and conventional power atrial fibrillation ablation on intraoperative acute pulmonary vein isolation, postoperative troponin levels, and atrial fibrillation recurrence.Methods:A retrospective selection was conducted on 105 patients with paroxysmal atrial fibrillation admitted to the Baoding NO.1 Central Hospital from January 2017 to December 2020. According to different treatment methods, they were divided into a high-power ablation group of 52 cases and a conventional power ablation group of 53 cases. The intraoperative rate of single circle acute pulmonary vein isolation, the recovery of electrical conduction after acute pulmonary vein isolation, and the location and number of points that need to be added were compared between the two groups; At the same time, two groups were compared in terms of surgical time, ablation time, surgical radiation exposure time and radiation dose, intraoperative complications postoperative cardiac troponin levels at 12 hours, and recurrence of atrial fibrillation within 1 year after ablation.Results:The intraoperative single loop pulmonary vein isolation rate and postoperative troponin levels in the high-power atrial fibrillation ablation group were higher than those in the conventional atrial fibrillation ablation group (all P<0.05). The surgical time, ablation time, and the number of sites and points that need to be added during surgery were less than those in the conventional atrial fibrillation ablation group (all P<0.05). There was no statistically significant difference in the incidence of intraoperative complications and postoperative atrial fibrillation recurrence between the two groups (all P>0.05). Conclusions:High power atrial fibrillation ablation has a higher single loop acute pulmonary vein isolation rate, fewer patch sites and points, shorter surgical time, and greater ablation damage compared to conventional ablation, and the clinical efficacy of the two groups is similar after surgery.
