Bioengineering, 2023 The transaortic valvular pressure gradient (TPG) plays a central role in decision-making for patients suffering from severe aortic stenosis. However, the flow-dependence nature of the TPG makes the diagnosis of aortic stenosis challenging since the ...

Percutaneous balloon valvuloplasty in a pregnant patient with pulmonary bioprosthetic valve stenosis
Revista Médica del Hospital General de México, 2022 The pulmonary valve’s anomalies can lead to the obstruction of the right ventricle’s outflow tract. This leads to the right ventricle’s pressure overload, dilation, hypertrophy and eventually his malfunction.

The role of mechano-electric feedbacks and hemodynamic coupling in scar-related ventricular tachycardia [PDF]
arXiv, 2021 Mechano-electric feedbacks (MEFs), which model how mechanical stimuli are transduced into electrical signals, have received sparse investigation by considering electromechanical simulations in simplified scenarios. In this paper, we study the effects of different MEFs modeling choices for myocardial deformation and nonselective stretch-activated ...

Analysis of Pain Hemodynamic Response Using Near-Infrared Spectroscopy (NIRS) [PDF]
The International Journal of Multimedia & Its Applications (IJMA)
Vol. 7, No. 2, April 2015, 2015 Despite recent advances in brain research, understanding the various signals for pain and pain intensities in the brain cortex is still a complex task due to temporal and spatial variations of brain hemodynamics. In this paper we have investigated pain based on cerebral hemodynamics via near-infrared spectroscopy (NIRS).

Hemodynamic Evaluation of Nonselective \u3b2-Blockers in Patients with Cirrhosis and Refractory Ascites [PDF]
, 2018 BACKGROUND:Nonselective \u3b2-blockers (NSBB) have been associated with increased incidence of paracentesis-induced circulatory dysfunction (PICD) and reduced survival in patients with cirrhosis and refractory ascites.

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 ...

Brain and Behavior, Volume 12, Issue 12, December 2022., 2022 Abstract Objective Patients with spontaneous subarachnoid hemorrhage (SAH) may develop refractory arterial cerebral vasospasm (CVS), which is the leading cause of death in SAH patients. This study explored the clinical diagnostic value of serum miR‐195‐5p levels in CVS after SAH (SAH + CVS) and its relationship with the prognosis of SAH + CVS.

Voxel2Hemodynamics: An End-to-end Deep Learning Method for Predicting Coronary Artery Hemodynamics [PDF]
arXiv, 2023 Local hemodynamic forces play an important role in determining the functional significance of coronary arterial stenosis and understanding the mechanism of coronary disease progression. Computational fluid dynamics (CFD) have been widely performed to simulate hemodynamics non-invasively from coronary computed tomography angiography (CCTA) images ...

Computational Simulations for Aortic Coarctation: Representative Results From a Sampling of Patients [PDF]
, 2011 Treatments for coarctation of the aorta (CoA) can alleviate blood pressure (BP) gradients(D), but long-term morbidity still exists that can be explained by altered indices of hemodynamics and biomechanics.
