As the pulsatile cardiac blood flow drives the heart valve leaflets to open and close, the flow
in the vicinity of the valve resembles a pulsed jet through a nonaxisymmetric orifice with a …

Recent advances in imaging techniques have allowed physicians to obtain robust
measurements of intracardiac flows in the clinical setting. Consequently, the physiological …

Background: Intraventricular fluid dynamics can be assessed clinically using imaging. The
contribution of vortex structures to left ventricular (LV) diastolic function has never been …

Purpose To evaluate viscous energy loss and the association with three‐dimensional (3D)
vortex ring formation in left ventricular (LV) blood flow during diastolic filling. Theory and …

The leaflets of the mitral valve interact with the mitral jet and significantly impact diastolic
flow patterns, but the effect of mitral valve morphology and kinematics on diastolic flow and …

The laws of fluid dynamics govern vortex ring formation and precede cardiac development
by billions of years, suggesting that diastolic vortex ring formation is instrumental in defining …

For the left ventricle (LV) to function as an effective pump it must be able to fill from a low left
atrial pressure. However, this ability is lost in patients with heart failure. We investigated LV …

Vortices may have a role in optimizing the mechanical efficiency and blood mixing of the left
ventricle (LV). We aimed to characterize the size, position, circulation, and kinetic energy …

INTRODUCTION: The role of flow on the progression of left ventricular (LV) remodeling has
been presumed, although measurements are still limited and the intraventricular flow pattern …

Aims To investigate the possibility that vorticity assessed by four-dimensional flow cardiac
magnetic resonance (4D-Flow CMR) in the left ventricle of patients with mild-to-moderate …
