Abstract:
Objective:To explore the safety and effectiveness of high power short duration (HPSD) ablation technique in elderly patients with atrial fibrillation.Methods:A total of 108 elderly patients with atrial fibrillation in the Department of Cardiology, the First Affiliated Hospital of Bengbu Medical University from January 2021 to June 2023 were randomly divided into the observation group (54 patients), who underwent HPSD catheter ablation and the control group (54 patients), who received conventional low power long duration (LPLD) catheter ablation. The radiation dose, ablation time, fluid infusion volume, pulmonary vein single lap isolation, and surgical complications were compared between the two groups. Follow up for 1 year after surgery to compare the success rates of the two groups.Results:The observation group had significantly lower radiation dose [(51.30±14.71)mGy vs. (77.77±13.97) mGy, P <0.01], ablation time [(57.98±16.95)min vs. (82.19±16.78)min, P <0.01]and saline infusion volume[(1284.31±212.07)mL vs.(1783.33±242.25)mL, P <0.01] compared with the control group. The pulmonary vein single lap isolation rates were similar in the two groups, and there were no serious surgical complications in the two groups. There were 17 cases of atrial fibrillation recurrence in the control group, higher than in the observation group (9 cases of recurrence), but there was no statistically significant difference between the two groups ( P =0.072). KM curve analysis showed that the maintenance time of sinus rhythm in the observation group was longer than that in the control group (Log Rank P =0.043). Conclusions:HPSD can significantly shorten the ablation time, reduce intraoperative saline infusion and radiation dose, and have a longer sinus rhythm time in elderly patients with atrial fibrillation. It is a safe and effective ablation method.
