This technique presents some potential complications, such as ostial coronary obstruction (e.g., Mitroflow; Sorin Group, Saluggia, Italy), and the risk of technical failure due to patient-prosthesis mismatch leading to excessively high post-procedural gradients, particularly in small bioprostheses (<23 mm)2. Until now, the majority of ViV procedures have been performed using Medtronic or Edwards ...
