Abstract：Objective To investigate the incidence and risk factors of arrhythmia after transcatheter aortic valve replacement(TAVR).Methods A total of 149 patients with aortic stenosis(AS)treated by TAVR in hospital from December 2021 to December 2022 were selected.Basic data of the patients were collected,patients were grouped according to whether they had arrhythmia after TAVR,the occurrence of arrhythmia in the patients was observed,and the influencing factors were analyzed by logistic regression.Results Arrhythmia occurred in 31 of 149 patients(20.81％).There were significant differences in body mass index,disease course,left ventricular ejection fraction(LVEF),tricuspid valve insufficiency and aortic occlusion time between arrhythmia group and non-arrhythmia group(P＜0.05).The influencing factors were included in multivariate logistic regression analysis,and the progressive method was adopted.The results showed that body mass index(OR=3.554,95％CI:1.167-10.819),disease duration(OR=3.080,95％CI:1.336-7.099),LVEF(OR=3.242,95％CI:3.114-24.821),tricuspid valve insufficiency(OR=1.394,95％CI:1.135-1.712)and aortic occlusion time(OR=1.910,95％CI:1.127-3.236)were all risk factors for arrhythmia during TAVR surgery(P＜0.05).Conclusion The incidence of arrhythmia after TAVR was 20.81％.Body mass index,course of disease,LVEF,tricuspid valve insufficiency and aortic occlusion time are all risk factors for arrhythmias.Prevention of these factors should be emphasized and effective measures should be taken to reduce the incidence of arrhythmias.
