The ACURATE neo2 valve will be implanted using a two-step mechanism during transfemoral transcatheter aortic valve implantation (TAVI). Balloon predilatation will be recommended in the ACURATE neo 2 valve group.

Isolated local anesthesia. Central venous lines, additional arterial lines for blood pressure monitoring, and urinary catheters will be avoided. Insertion of temporary pacemakers is optional and should be avoided whenever possible, and peri-procedural pacing can then be performed on the left ventricular wire. Patients will be directly transferred to the cardiology ward after the procedure, which can be postponed in case of complications.

The Evolut Pro, Pro+ or FX valve is positioned in a controlled manner either without pacing or under 'slow-rapid' pacing with allowance for limited repositioning and is anchored to the annulus and ascending aorta.

Sedation should be titrated to a Richmond Agitation Sedation Scale (RASS) of 0 to -2 according to local standard of care.The use of EEG monitoring (i.e. BIS, Sedline) can be applied. Continuous CO2-monitoring via face mask should be established during sedation. All patients will receive supplemental oxygen by face mask to maintain an oxygen saturation of approximately 95%. The use of central venous catheters, additional arterial lines for blood pressure monitoring, and urinary catheters can be implemented according to local institutional standards.
