Abstract:
Objective:To investigate the predictive factors of delayed high atrioventricular block(DH-AVB) after transcatheter aortic valve replacement(TAVR) and the risk of pacemaker implantation.Methods:Patients who underwent TAVR in the heart center of Qingdao Municipal Hospital from January 2019 to October 2022 were retrospectively analyzed. A total of 85 patients who met the criteria of transcatheter aortic valve replacement were included in this study. They were divided into DH-AVB group after TAVR and non-DH-AVB group after TAVR. The data were analyzed by univariate analysis and binary logistic regression analysis. Results:The results showed that the over-rate of valve implantation( OR=3.582, 95% CI: 0.923-13.902, P=0.048), the depth of valve implantation( OR=3.727, 95% CI: 1.138-12.204, P=0.030), the new postoperative CLBBB( OR=5.958, 95% CI: 1.258-28.220, P=0.025)and the prolonged PR time limit( OR=1.036, 95% CI: 1.008-1.065, P=0.011) were independent risk factors for DH-AVB after TAVR. With the progress of conduction block, patients in DH-AVB group had a higher pacemaker implantation rate(81.82 % vs.18.18 %, P<0.001). Conclusion:The excessive rate of valve implantation, the depth of valve implantation, the new complete left bundle branch block(CLBBB) and the prolonged PR time after operation are independent predictors of delayed complete atrioventricular block after TAVR. The incidence of pacemaker implantation in patients with delayed complete atrioventricular block after operation is higher.
