Including Aortic Valve Morphology in Computational Fluid Dynamics Simulations: Initial Findings and Application to Aortic Coarctation [PDF]
, 2012 Computational fluid dynamics (CFD) simulations quantifying thoracic aortic flow patterns have not included disturbances from the aortic valve (AoV). 80% of patients with aortic coarctation (CoA) have a bicuspid aortic valve (BAV) which may cause adverse ...

Cardio-ankle vascular index (CAVI) measured by a new device: protocol for a validation study
BMJ Open, 2020 Introduction Cardio‐ankle vascular index (CAVI) is a new marker of arterial stiffness (AS) that can assess vascular wall stiffness in the aorta, femoral artery and tibial artery. CAVI is less affected by blood pressure at the time of measurement than the

Surgical vs. transcatheter arotic valve replacement in patients over 75 years with aortic stenosis: sociodemographic profile, clinical characteristics, quality of life and functionality [PDF]
PeerJ, 2023 Background Aortic valve stenosis (AVS) affects 25% of the population over 65 years. At present, there is no curative medical treatment for AVS and therefore the surgical approach, consisting of transcatheter aortic valve replacement (TAVR) or surgical ...

Hemodynamically informed parcellation of cerebral FMRI data [PDF]
, 2014 Standard detection of evoked brain activity in functional MRI (fMRI) relies on a fixed and known shape of the impulse response of the neurovascular coupling, namely the hemodynamic response function (HRF).
