Structure‐based finite strain modelling of the human left ventricle in diastole [PDF]

International Journal for Numerical Methods in Biomedical Engineering, 2013
Finite strain analyses of the left ventricle provide important information on heart function and have the potential to provide insights into the biomechanics of myocardial contractility in health and disease. Systolic dysfunction is the most common cause

The Ependymal Region Prevents Glioblastoma From Penetrating Into the Ventricle via a Nonmechanical Force

Frontiers in Neuroanatomy, 2021
BackgroundIntraventricular penetration is rare in glioblastoma (GBM). Whether the ependymal region including the ependyma and subventricular zone (SVZ) can prevent GBM invasion remains unclear.MethodsMagnetic resonance imaging (MRI) and haematoxylin ...

Left Ventricular Assist Device Pump Obstruction Reduces Native Heart Efficiency

Bioengineering, 2023
Obstruction of the LVAD flow path can occur when blood clots or tissue overgrowth form within the inflow cannula, pump body, or outflow graft, and it can lead to thrombus, embolism, and stroke.
