TAVR: Any CE-Mark approved transcatheter aortic bioprosthesis may be used in the study, and the choice is at the discretion of the local TAVR team. The transfemoral TAVR procedure may be performed under general anaesthesia, local anaesthesia/conscious sedation, or local anesthesia. Percutaneous coronary intervention (PCI) can be performed up to 30 days prior to TAVR or as a hybrid procedure.
