Polymeric heart valves for surgical implantation, catheter-based technologies and heart assist devices.
TL;DR: It is suggested that there is a greater degree of instability in thermoplastic materials than hitherto believed so that significant challenges remain in the search for the combination of durability and biocompatibility that would allow polymeric valves to become a clinical reality for surgical implantation.

Impact of Detergent-Based Decellularization Methods on Porcine Tissues for Heart Valve Engineering
Annelies Roosens,Pamela Somers,Filip De Somer,Víctor Carriel,Víctor Carriel,Guido Van Nooten,Ria Cornelissen +6 more
TL;DR: It is clearly demonstrated that the decellularization agents have more impact on pericardial tissues than on heart valve leaflets, and it is advisable to use valvular rather than pericARDial matrices for the purpose of tissue engineering of heart valves.

Valve thrombosis following transcatheter aortic valve implantation: a systematic review.
Juan G. Córdoba-Soriano,Rishi Puri,Ignacio J. Amat-Santos,Henrique Barbosa Ribeiro,Omar Abdul-Jawad Altisent,Maria Del Trigo,Jean-Michel Paradis,Eric Dumont,Marina Urena,Josep Rodés-Cabau +9 more
TL;DR: Although a rare, yet likely under-reported complication of post-transcatheter aortic valve implantation, progressive dyspnea coupled with an increasing transvalvular gradient on echocardiography within the months following the intervention likely signifies valve thrombosis.
Journal ArticleDOI
Fixation of Bovine Pericardium-Based Tissue Biomaterial with Irreversible Chemistry Improves Biochemical and Biomechanical Properties
TL;DR: It is demonstrated that TRI-treated BP is more compliant than GLUT- treated BP and exhibited better resistance to enzymatic degradation in vitro and calcification in vivo when implanted subcutaneously in juvenile rats for up to 30 days.

Flow patterns around heart valves: A numerical method
TL;DR: In this paper, the Navier-Stokes equations on a rectangular domain are applied to the simulation of flow around the natural mitral valve of a human heart valve, where the boundary forces are of order h − 1, and because they are sensitive to small changes in boundary configuration, they tend to produce numerical instability.

Curves and Surfaces for Computer-Aided Geometric Design: A Practical Guide
TL;DR: The fourth edition has been thoroughly updated and revised to include a new chapter on recursive subdivision, as well as new sections on triangulations and scattered data interpolants, and the disk in the back of the book has been updated to include all of the programs, as the data sets from the text.

The Significance of Fatigue Crack Closure
TL;DR: Al alloy sheet fatigue crack closure under cyclic tensile loading, deriving expression for crack propagation rate in terms of effective stress amplitude as discussed by the authors, was derived for the first time in the literature.
