Comparative study of wall shear stress at the ascending aorta for different mechanical heart valve prostheses [PDF]

, 2019
An experimental study is reported which investigates the wall shear stress (WSS) distribution in a transparent model of the human aorta comparing a bileaflet mechanical heart valve (BMHV) with a trileaflet mechanical heart valve (TMHV) in physiological ...

Raman Microscopy at the Organic–Inorganic Interfaces in Human Calcified Aortic Valves Shows the Co‐Existence of Whitlockite Crystals and Carbonated Hydroxyapatite‐Mineralized Collagen Fibrils

Advanced Functional Materials, EarlyView.
This study advances our understanding of aortic valve stenosis by capturing spatially resolved chemical and structural changes at the nanoscale. The findings highlight the potential of combined Raman and electron microscopy for understanding calcification mechanisms across diverse tissue types.

Study of mitral valve in human cadaveric hearts

Heart Views, 2012
Objectives: The mitral valve is a complex structure that is altered by disease states. The classical image of the mitral valve is a bicuspid valve with two leaflets and two papillary muscles.

Infectious seeds of valve calcification: Exploring the bacterial hypothesis in the pathogenesis of calcific aortic valve disease. [PDF]

Eur J Clin Invest
Abstract Background Calcific aortic valve disease (CAVD) is a multifactorial condition characterized by progressive leaflet calcification with a potential role for bacterial colonization in its pathogenesis. This study investigates clinical, microbiological and molecular features of calcified versus non‐calcified aortic regurgitation (AR) valves ...

Aortic valve and aortic arch pathology after coarctation repair [PDF]

, 2003
OBJECTIVE: To investigate the incidence of clinical problems related to a bicuspid valve (aortic stenosis and regurgitation) and the incidence of ascending aorta and aortic arch pathology in combination with coarctation repair.

Spatially Tailorable Liquid Crystalline Elastomer Alignment During Digital Light Process 3D Printing

Advanced Functional Materials, EarlyView.
Here, we report the fabrication of 3D printable liquid crystalline elastomer (LCE) structures with spatially tailorable alignment domains within the same layer. This work addresses the long‐standing challenge of preparing complex 3D LCE architectures with patterned functional domains to achieve nonlinear deformations. Fabrication of multi‐domains in 3D

Debate: Severe bicuspid aortic valve stenosis in non-high-risk surgical patients. In favor of surgery

REC: Interventional Cardiology (English Ed.), 2022
QUESTION: What is the prevalence of bicuspid aortic valve in the population currently eligible for surgical aortic valve replacement? ANSWER: The prevalence of bicuspid aortic valve is around 1% to 2% of the population. Somewhere between 27&

A Versatile Engineering Platform for the Fabrication of Prosthetic Venous Valves Using Electrospinning

Advanced Healthcare Materials, EarlyView.
Percutaneous prosthetic venous valves are fabricated by embedding stents in an electrospun matrix that extends luminally to form leaflets. The design shields leaflets from hyperplastic cells, isolates struts from blood contact, and avoids discrete anchoring points.
