Open-heart transseptal transcatheter mitral valve implantation with mitral annular calcification [PDF]

Journal of Cardiology Cases, 2020
Mitral valve replacement (MVR) using a prosthesis of transcatheter aortic valve implantation for mitral annular calcification (MAC) is an alternative procedure which is very different from a conventional MVR and is safe. Acceptable results including mortality and morbidity have been reported.

Meta‐Rod Mechanical Metamaterials With Programmable Reconfiguration

Advanced Functional Materials, EarlyView.
Existing mechanical metamaterials achieve programmable large deformations in planar square or cubic configurations, restricted by required complex boundary conditions. This research proposes a 1D metamaterial, Meta‐rod, with linear, bending, twisting, area, and volume deformation modes.

From Clinic to Computation: Multiscale Bioengineering Strategies for Durable Biological Aortic Valve Replacements

Advanced Functional Materials, EarlyView.
Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.

Combined mitral valve repair and heart transplantation

Clinical Case Reports, 2018
Key Clinical MessageIn times of donor organ shortage, organs with extended allocation criteria, for example, valve pathologies, have to be taken into consideration for transplantation. The donor pool can be extended to hearts with mitral valve insufficiency.
