Coronary access after transcatheter aortic valve implantation (TAVI) procedures can be challenging due to anatomical, procedural or valve-related factors12. This challenge is further augmented during valve-in-valve (ViV) procedures due to the additional presence of transcatheter or surgical valve frames and leaflets3. Dedicated valve-specific cannulation techniques are required for operators to achieve coronary access, particularly in challenging scenarios24. To date, specific coronary cannulation techniques have only been described for the CoreValve/Evolut (Medtronic) and SAPIEN (Edwards Lifesciences) valve platforms following native aortic valve TAVI24.
Therefore, we performed ex vivo simulations of coronary access in a computed tomography-derived patient-specific pulsatile ...
