Interdisciplinary three-step strategy to treat aortic stenosis and coronary artery disease in a patient with end-stage chronic obstructive pulmonary disease [PDF]

open access: yes, 2012
Background: Valvular aortic stenosis is a common disease in the elderly, often in multimorbid patients. It is often associated with coronary artery disease and peripheral artery disease.

SOURCE 3: 1-year outcomes post-transcatheter aortic valve implantation using the latest generation of the balloon-expandable transcatheter heart valve

open access: yesEuropean Heart Journal, 2017
Aims Transcatheter aortic valve implantation (TAVI) has developed from a procedure for patients with aortic stenosis inoperable or high risk for surgery, into a treatment option even for intermediate risk elderly patients.

Nanostructured 316L Stainless Steel Stent Surfaces Improve Corrosion Resistance, and Enhance Endothelization and Hemocompatibility

open access: yesAdvanced Materials Interfaces, EarlyView.
This study investigates the impact of nanostructured surface modification on corrosion resistance, HUVEC functions, and platelet interactions of 316L SS for cardiovascular stents. Nanostructured surfaces enhanced HUVEC proliferation, migration, and angiogenesis‐related gene expression while reducing platelet adhesion and hemolysis.

Predicting Disease Progression and Mortality in Aortic Stenosis: A Systematic Review of Imaging Biomarkers and Meta-Analysis

open access: yesFrontiers in Cardiovascular Medicine, 2018
Background: Detecting among patients with aortic stenosis (AS) those who are likely to rapidly progress, yet potentially benefiting from prophylactic aortic valve replacement, is needed for improved patient care.

A novel mathematical technique to assess of the mitral valve dynamics based on echocardiography [PDF]

open access: yesarXiv, 2015
Purpose: The mechanics of the mitral valve leaflet as a nonlinear, inelastic and anisotropic soft tissue results from an integrated response of many mathematical/physical indexes' that illustrate the tissue. In the past decade, finite element modeling of complete heart valves has greatly aided evaluation of heart valve surgery, design of bioprosthetic ...

Computationally Designed 3D Printed Self-Expandable Polymer Stents with Biodegradation Capacity for Minimally Invasive Heart Valve Implantation: A Proof-of-Concept Study

open access: yes3D Printing and Additive Manufacturing, 2017
The evolution of minimally invasive implantation procedures and the in vivo remodeling potential of decellularized tissue-engineered heart valves require stents with growth capacity to make these techniques available for pediatric patients.

The Role of Silicon Technology in Organ‐On‐Chip: Current Status and Future Perspective

open access: yesAdvanced Materials Technologies, EarlyView.
This review explores the potential of silicon micro‐nanofabrication technologies in advancing organ‐on‐chip systems. The integration of actuation and sensing modalities, highlight emerging technologies is discussed for combining silicon‐based and polymer‐based components, and emphasize the need for robust, high‐throughput, and customizable organ‐on ...

3D Wiring Microelectrodes in a PMMA Microfluidic Device by Vacuum Filling Method

open access: yesAdvanced Materials Technologies, EarlyView.
This paper proposes a method for fabricating 3D wiring microelectrodes in arbitrary designs within 3D‐printed microfluidics. By attaching a PDMS lid and using vacuum filling, low‐melting‐point alloy (LMA) is introduced into microchannels. This enables the creation of 50 µm microelectrodes, including complex shapes.

Relationship between fibre orientation and tensile strength of natural collagen membranes for heart valve leaflets [PDF]

open access: yes, 2011
Heart valve prostheses are used to replace native heart valves which that are damaged because of congenital diseases or due to ageing. Biological prostheses made of bovine pericardium are similar to native valves and do not require any anticoagulation ...
