Figure 3 VinV Implantation in the Mitral Position Within a Conventional 25-mm Carpentier Edwards Porcine Prosthesis
(A) Valve positioning within the conventional mitral valve prosthesis. The superstiff guidewire is passed from the apex retrogradely through the mitral prosthesis, curves in the left atrium, and is anchored in a pulmonary vein. (B) Mitral valve-in-a-valve (VinV) in position.
