Key result
Novel TMVR devices and access routes expand treatment options for complex mitral anatomy.
Why the study?
High and prohibitive surgical risk scenarios favor transcatheter mitral valve replacement for mitral regurgitation reduction, warranting a review of evolving technologies, anchoring systems, and access challenges.
This review highlights the evolving technologies, anchoring systems, and access modalities for transcatheter mitral valve replacement in high-risk surgical patients.
May guide device innovation for complex mitral anatomies; leaves open the need for randomized outcome data before clinical adoption.
Higher and prohibitive mitral valve disease surgical scenarios are preferred cases for transcatheter mitral valve replacement as they offer unrelenting mitral valve regurgitation reduction. This review entails medical technologies that are evolving bioprosthetic devices for mitral valve repair and replacement purposes. Transcatheter mitral valve replacement is compared with transcatheter aortic valve implantation based on the etiology and driving factors. Leading anchoring systems to place and fix the mitral valve prosthesis in left atrium/ventricle annulus are discussed. Furthermore, accessing modalities to stretch to the mitral valve including transapical, trans- aorta and transseptal are included along with the associated key challenges.

Zafar et al. (2023) conducted a review in Mitral valve disease. Transcatheter mitral valve replacement (TMVR) was evaluated. Transcatheter mitral valve replacement is evolving with multiple novel bioprosthetic devices and access modalities to address challenging anatomical constraints such as a large D-shaped annulus.
