Transcatheter mitral valve replacement versus redo surgery for mitral prosthesis failure: A systematic review and meta-analysis [PDF]
Frontiers in Cardiovascular Medicine, 2023 BackgroundTranscatheter mitral valve replacement (TMVR) has emerged as an alternative to redo surgery. TMVR compared with redo surgical mitral valve replacement (SMVR) in patients with mitral prosthesis failure remains limited.

Biomechanical Evaluation of a Novel Bionic Hip Prosthesis Designed for Optimized Load Transfer and Initial Stability [PDF]
Orthopaedic SurgeryObjective In total hip arthroplasty, the femoral component design requires a trade‐off between initial stability and stress shielding. We designed the new bionic hip arthroplasty (BHA) prosthesis with compression and tension screws to mimic compression ...
