Abstract

Conduction disorders and permanent pacemaker implantation are common complications in patients who undergo transcatheter aortic valve implantation (TAVI). The aim of this study was to assess the incidence and clinical significance of new bundle branch block in patients who underwent TAVI with the Medtronic CoreValve Revalving System (MCRS) or the Edwards SAPIEN valve (ESV). Data from 238 patients with no previous pacemaker implantation, left bundle branch block (LBBB) or right bundle branch block at baseline electrocardiography who underwent TAVI with either MCRS (n = 87) or ESV (n = 151) bioprostheses from 2007 to 2011 were analyzed. New-onset LBBB occurred in 26.5% patients (n = 63): 13.5% with the ESV (n = 20) and 50.0% with the MCRS (n = 43) (p = 0.001). Permanent pacemaker implantation was required in 12.7% of patients (n = 8) because of complete atrioventricular block (ESV n = 2, MCRS n = 4), LBBB and first degree atrioventricular block (MCRS n = 1) and new-onset LBBB associated with sinus bradycardia (MCRS n = 1). At discharge, LBBB persisted in 8.6% of ESV patients (n = 13) and 32.2% of MCRS patients (n = 28) (p = 0.001). On multivariate analysis, the only predictor of LBBB was MCRS use (odds ratio 7.2, 95% confidence interval 2.9 to 17.4, p
