N2 - Predilatation has been historically considered a mandatory step before transcatheter aortic valve implantation (TAVI) since it facilitates valve crossing and prosthesis delivery, ensures optimal valve expansion and improves hemodynamic stability during valve deployment. However, as a result of procedural evolution over time, direct TAVI (without pre-implantation balloon aortic valvuloplasty) has emerged as an interesting option to simplify the procedure and to avoid potential valvuloplasty-related complications. Several real-world retrospective studies and one small randomised study have shown that direct TAVI (with both self-expanding and balloon-expandable prostheses) is feasible, safe and associated with outcomes similar to standard TAVI with pre-implantation balloon aortic valvuloplasty. In the absence of high-quality, robust evidence, the current review aims to discuss the advantages and disadvantages of omitting predilatation prior to TAVI.
