%X The number of transcatheter mitral valve treatment options has been increasing. Among these, transcatheter mitral valve-in-ring or valve-in-mitral annular calcification (MAC) are more challenging compared to transcatheter mitral valve-in-valve therapy because of a shorter and non-circular landing zone and difficulty in achieving optimal coaxiality. In addition, the risk of left ventricular outflow tract (LVOT) obstruction is higher as the anterior mitral leaflet could cover the transcatheter heart valve and obstruct the LVOT
