The main objective is to assess the predictive value of the pre-TAVI infrahelic conduction time interval (infraheal conduction time measured before percutaneous aortic valve implantation) on the risk of Pacemaker implantation at 30 days post-TAVI, in patients with right bundle branch block prior to surgery.~The aim of the study is to identify a pre-interventional marker of the risk of rhythmological complication after the TAVI procedure (Transcatheter Aortic Valve Implantation), in order to better anticipate it.~This is an interventional, prospective, longitudinal (follow-up: 12 months), multicenter (4 centers) study.
The purpose of the study is implantation of a Pacemaker at 30 days for occurrence of a high-grade conduction disorder per- or post-procedure (yes/no)
