Key result
Transfemoral TAVI without predilatation was feasible, achieving 100% procedural success and 0% 30-day mortality, with significantly reduced radiation and contrast dye compared to predilatation.

May support omitting predilatation to reduce radiation and contrast; hypothesis-generating and requires randomized confirmation before practice change.

Does transfemoral TAVI without predilatation improve procedural safety and feasibility compared to TAVI with predilatation in patients with native aortic valve stenosis?
Transfemoral TAVI without predilatation using a balloon-expandable valve is feasible, safe, and reduces radiation and contrast use compared to standard predilatation.
Möllmann et al. (2014) conducted a cohort in Stenosis of the native aortic valve (n=56). Transfemoral TAVI without predilatation vs. Transfemoral TAVI with predilatation was evaluated on Procedural success. Transfemoral TAVI without predilatation was feasible, achieving 100% procedural success and 0% 30-day mortality, with significantly reduced radiation and contrast dye compared to predilatation.
