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.

Hemodynamic and microcirculatory early adaptations following transcatheter aortic valve implantation (TAVI): A physiological pilot study

open access: yesEuropean Journal of Clinical Investigation, EarlyView.
This pilot physiological study, involving 20 patients with severe aortic stenosis, shows that transcatheter aortic valve implantation (TAVI) induces rapid changes in both macrocirculatory parameters, reflecting the release of chronic obstruction. We observed improved tissue perfusion by postoperative Day 1, independent of macrocirculatory parameters ...

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

Influence of nanohydroxyapatite mouthwash on the growth of Candida albicans biofilm on milled denture surfaces: An in vitro study

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose There is a need for effective solutions for the persistent prevalence of denture stomatitis (DS) in denture‐wearing populations. This study assessed the impact of nanohydroxyapatite (nanoHAP) nanoparticles on Candida albicans biofilm formation on milled polymethylmethacrylate (PMMA) denture bases.

Structural evolution of mechanical heart valves (review)

open access: yesВестник трансплантологии и искусственных органов
Prosthetic heart valves are widely used biomedical devices. The need for these prostheses is increasing due to the increasing life expectancy of the general population and the consequent incidence of age-related degenerative valvular defects.

Fluid-structure interaction simulation of mechanical aortic valves: a narrative review exploring its role in total product life cycle

open access: yesFrontiers in Medical Technology
Over the last years computer modelling and simulation has emerged as an effective tool to support the total product life cycle of cardiovascular devices, particularly in the device preclinical evaluation and post-market assessment.
