Comments Surgery:

• transapical implantation only

Comments Echocardiography:

• no size-specific data on hemodynamic performance and no EOAi calculator available
• 30d EOA and transvalvular gradient results of reference number 2 are not size-specific but based on a mixed group of patients with Enganger prostheses of sizes 23mm and 26mm.
