Optimal Hemodynamics During Left Ventricular Assist Device Support Are Associated With Reduced Readmission Rates

open access: yesCirculation: Heart Failure, 2019
Background: Left ventricular assist device (LVAD) therapy improves the hemodynamics of advanced heart failure patients. However, it is unknown whether hemodynamic optimization improves clinical outcomes.

Computational Simulations for Aortic Coarctation: Representative Results From a Sampling of Patients [PDF]

open access: yes, 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.

Functional assessment of coronary artery disease by intravascular ultrasound and computational fluid dynamics simulation

open access: yesRevista Portuguesa de Cardiologia, 2014
Clinical trials have shown that functional assessment of coronary stenosis by fractional flow reserve (FFR) improves clinical outcomes. Intravascular ultrasound (IVUS) complements conventional angiography, and is a powerful tool to assess atherosclerotic

The biophysical role of hemodynamics in the pathogenesis of cerebral aneurysm formation and rupture.

open access: yesNeurosurgical Focus, 2019
The pathogenesis of intracranial aneurysms remains complex and multifactorial. While vascular, genetic, and epidemiological factors play a role, nascent aneurysm formation is believed to be induced by hemodynamic forces. Hemodynamic stresses and vascular

High WSS or Low WSS? Complex Interactions of Hemodynamics with Intracranial Aneurysm Initiation, Growth, and Rupture: Toward a Unifying Hypothesis

open access: yesAmerican Journal of Neuroradiology, 2014
Summary: Increasing detection of unruptured intracranial aneurysms, catastrophic outcomes from subarachnoid hemorrhage, and risks and cost of treatment necessitate defining objective predictive parameters of aneurysm rupture risk.

Percutaneous balloon valvuloplasty in a pregnant patient with pulmonary bioprosthetic valve stenosis

open access: yesRevista 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 Impact of Left Ventricular Performance and Afterload on the Evaluation of Aortic Valve Stenosis: A 1D Mathematical Modeling Approach

open access: yesBioengineering, 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 ...
