Factors influencing long-term survival after aortic valve replacement. [PDF]

, 1980
In the aortic stenosis group, the left ventricular (LV) muscle mass index was a good parameter for predicting the prognosis. Associated mitral valve disease had no influence on long term survival after aortic valve replacement.

Aortic valve repair for insufficiency in older children offers unpredictable durability that may not be advantageous over a primary Ross operation†.

European Journal of Cardio-Thoracic Surgery, 2016
OBJECTIVES To evaluate the durability of aortic valve (AoV) repair relative to other strategies for children with significant aortic insufficiency (AI). METHODS From 2001 to 2012, 90 children with greater than or equal to moderate AI underwent surgery.

A multicentre, propensity score matched analysis comparing a valve-sparing approach to valve replacement in aortic root aneurysm: Insight from the AVIATOR database

European Journal of Cardio-Thoracic Surgery, 2022
OBJECTIVES Our goal was to evaluate the outcome of valve-sparing root replacement (VSRR) and to compare the outcomes to those of patients having composite valve–graft conduit aortic root replacement (CVG-ARR) in a cohort of patients with aortic root ...

Trans-apical aortic valve implantation for quadricuspid aortic valve with aortic regurgitation using J-valve system: a case reports

Journal of Cardiothoracic Surgery, 2021
Background Quadricuspid aortic valve (QAV) is a rare congenital heart defect usually accompanied with different hemodynamic abnormalities. Due to the rarity of QAV, treatment and prognosis of QAV patients with aortic regurgitation still remain ...

Immersed boundary-finite element model of fluid-structure interaction in the aortic root [PDF]

, 2015
It has long been recognized that aortic root elasticity helps to ensure efficient aortic valve closure, but our understanding of the functional importance of the elasticity and geometry of the aortic root continues to evolve as increasingly detailed in vivo imaging data become available.

Material transport in the left ventricle with aortic valve regurgitation [PDF]

Physical Review Fluids, 3(11), 113101 (2018), 2018
This experimental in vitro work investigates material transport properties in a model left ventricle in the case of aortic regurgitation, a valvular disease characterized by a leaking aortic valve and consequently double-jet filling within the elastic left ventricular geometry.

Macrophage HM13/SPP Enhances Foamy Macrophage Formation and Atherogenesis

Advanced Science, EarlyView.
Previous research suggests that AIP may prevent atherogenic foamy macrophage formation. This study reveals that AIP, via its chaperone interaction with AHR, inhibits p38‐c‐JUN‐mediated transactivation of HM13, which encodes the ERAD protease HM13/SPP. HM13/SPP promotes foamy macrophage formation in addition to atherogenesis and plaque foamy macrophage ...

Immersed boundary model of aortic heart valve dynamics with physiological driving and loading conditions [PDF]

Int J Numer Meth Biomed Eng, 28(3):317-345, 2012, 2017
The immersed boundary (IB) method is a mathematical and numerical framework for problems of fluid-structure interaction, treating the particular case in which an elastic structure is immersed in a viscous incompressible fluid. The IB approach to such problems is to describe the elasticity of the immersed structure in Lagrangian form, and to describe ...

Uncover Hidden Physical Information of Soft Matter by Observing Large Deformation

Advanced Science, EarlyView.
Detecting internal abnormalities in soft matter remains challenging due to its heterogeneous nature. This study introduces a method that infers hidden physical properties by matching observed deformation with simulation through parallel Bayesian optimization.
