Transapical mitral valve-in-valve implantation for failed bioprosthetic valve using the J-valve system with locator device: early and mid-term outcomes.

ABSTRACT:

Background

Prior to the approval of the Sapien valve in 2020, there were no commercially available short-frame valves for transapical mitral valve-in-valve (MVIV) implantation. In January 2019, we first attempted the reverse mounted J-valve for transapical MVIV implantation with good clinical results. The present study aimed to explore the safety and effectiveness of transapical MVIV implantation with the J-valve reversely mounted on the delivery system.

Methods

Patients who underwent transapical MVIV implantation using the J-valve were analyzed from January 2019 to December 2020 with a 1-year follow-up. Before the procedure, computed tomography (CT) angiography data were analyzed to determine the inner diameter, left ventricular outflow tract (LVOT), and coaxial angel. An o
