Deskripsi
Transcatheter mitral valve-in-valve replacement (TMVR) offers a less invasive strategy for managing bioprosthetic mitral valve dysfunction. TMVR positioning is challenging in the setting of a radiolucent bioprosthetic sewing ring. We present 2 cases demonstrating the roles of fluoroscopy and echocardiography in guiding TMVR placement within bioprostheses with radiolucent sewing rings. (Level of Difficulty: Intermediate.)
