Résumé
New-onset left bundle branch block (LBBB) is a frequent complication after transcatheter aortic valve replacement (TAVR) and provides an opportunity to study dyssynchrony immediately following acute LBBB. This study aims to (1) assess echocardiographic dyssynchrony in acute TAVR-induced LBBB (TAVR-LBBB), and (2) compare dyssynchrony parameters among different patient groups with LBBB. The study enrolled all TAVR-LBBB patients at Ghent University Hospital between 2013 and 2019. First, acute TAVR-LBBB dyssynchrony was assessed by: (1) septal flash (SF); (2) interventricular mechanical delay (IVMD; cut-off ≥ 40 ms) and (3) presence of 'classical dyssynchronous strain pattern' assessed with speckle tracking. Secondly, acute TAVR-LBBB patients with SF (LBBB
