Key result
Transaortic TAVI remains a safe and efficient alternative access route for patients with severe aortic stenosis and unsuitable femoral arteries, particularly when supra-aortic calcifications preclude other approaches.
Why the study?
Current literature does not clearly favor one alternative access route over another in patients with unsuitable femoral arteries, and an updated overview on the indications, technical aspects, and clinical data for transaortic transcatheter aortic valve implantation is needed.
Does transaortic transcatheter aortic valve implantation provide a safe and effective alternative access route in patients with severe aortic stenosis unsuitable for transfemoral access?
Does transaortic transcatheter aortic valve implantation provide a safe and effective alternative access route in patients with severe aortic stenosis unsuitable for transfemoral access?
Transaortic TAVI remains a valuable alternative access route for patients with severe aortic stenosis who are unsuitable for transfemoral access, particularly when supra-aortic calcifications preclude transaxillary or transcarotid approaches.

May support transaortic TAVI when femoral access is unsuitable; leaves open need for randomized comparisons of long-term outcomes.
Transaortic (TAo) transcatheter aortic valve implantation has become a valid alternative access route in patients with unsuitable femoral arteries. The current literature does not allow to clearly favor one of the alternative access routes. Every approach has its specific advantages. Transaortic (TAo) access is of particular importance in the case of calcifications of the supra-aortic branches and the aortic arch, as under these circumstances other alternative access routes, such as transaxillary or transcarotid, are not feasible. The purpose of this minireview is to give an overview and update on TAo transcatheter aortic valve implantation focusing on indication, technical aspects, and recent clinical data.

Stastny et al. (2022) conducted a review in Severe aortic stenosis. Transaortic Transcatheter Aortic Valve Implantation (TAo TAVI) vs. Other TAVI access routes (transfemoral, transapical, transaxillary, transcarotid) was evaluated. Transaortic TAVI remains a safe and efficient alternative access route for patients with severe aortic stenosis and unsuitable femoral arteries, particularly when supra-aortic calcifications preclude other approaches.
