  • Title: A novel method of prosthetic leaflet modification to enable transcatheter mitral valve-in-valve replacement.

    Journal: Catheter Cardiovasc Interv; 2023 Nov; 102(6):1149-1153. PubMed ID: 37855217.
    Abstract:
    Left ventricular outflow tract (LVOT) obstruction from the displaced prosthetic anterior mitral leaflet is a life-threatening complication that can occur during valve-in-valve (ViV) transcatheter mitral valve replacement (TMVR). Laceration of the anterior mitral leaflet to prevent outflow obstruction is a well-established transcatheter technique to mitigate the risk of LVOT obstruction in high-risk anatomies. In this report, we present a novel transseptal technique of prosthetic leaflet modification to prevent LVOT obstruction during ViV TMVR.
