A Novel Polymer Film to Develop Heart Valve Prostheses

open access: yesPolymers
Polymer heart valves are a promising alternative to bioprostheses, the use of which is limited by the risks of calcific deterioration of devitalized preserved animal tissues. This is especially relevant in connection with the increasingly widespread use of transcatheter valves.

An Original Single-Body Synthetic Heart Valve: Feasibility Study And Prototype Realization [PDF]

open access: yes
The research for durable, non-thrombogenic heart valve prostheses able to overcome the limits of biological and mechanical ones, promoted the development of synthetic valves. Their success has been hampered by lack of durability, due to calcification and

In Vitro Calcification of Bioprosthetic Heart Valves: Method Validation by Comparative Heart Valve Calcification Testing

open access: yesArtificial Organs, EarlyView.
We have developed a unique method for pre‐clinical heart valve prostheses evaluation of calcification propensity. Results from the test can directly be translated into improvements of prostheses design, materials, and anti‐calcification treatments, and therefore have a significant impact on heart valve prostheses quality and patient care in the future.

Purinergic ecto-enzymes in human and ovine aortic valves: indicators of bacterial nanocellulose scaffold cellularization

open access: yesArtificial Cells, Nanomedicine, and Biotechnology
Purinergic signalling pathways play a vital role in the biological functions of the aortic valve (AV) through nucleotide and adenosine-dependent receptor effects.

Three-Cusp View Orientation in TAVI: Evaluating LOA Versus Non-LOA Impact on Outcomes With Contemporary Valve Prostheses. [PDF]

open access: yesCatheter Cardiovasc Interv
ABSTRACT Background Optimal projection views during transcatheter aortic valve implantation (TAVI) procedures are critical for procedural success and patient outcomes. Aims This study investigated the influence of 3‐cusp view orientation—line of alignment (LOA) versus non‐LOA—on procedural outcomes in patients undergoing TAVI with contemporary ...

A case study of technology transfer: Rehabilitative engineering at Rancho Los Amigos Hospital [PDF]

open access: yes
The transfer of NASA technolgy to rehabilitative applications of artificial limbs is studied. Human factors engineering activities range from orthotic manipulators to tiny dc motors and transducers to detect and transmit voluntary control signals.

Paravalvular leakage after mitral valve replacement: improved long-term survival with aggressive surgery? [PDF]

open access: yes, 2017
Background: Following mitral valve replacement, surgical closure of paravalvular leaks is usually advised in severely symptomatic patients and in those requiring blood transfusions for persisting haemolysis.
