Turbulent kinetic energy from CMR identifies disturbed diastolic flow in myopathic left ventricles
نویسندگان
چکیده
Background Turbulent blood flow is a cause of energy loss in the cardiovascular system, and can thus be seen as a measure of flow inefficiency. Novel 4D flow CMR methods permit estimation of intracardiac turbulent kinetic energy (TKE). On the basis of the Reynolds number, one might expect that larger left ventricular (LV) size would promote higher TKE values, and thus lower flow efficiency. In this study, we hypothesized that the TKE of diastolic inflow would be larger in the dilated LVs of heart failure patients compared to normal LVs.

Turbulent kinetic energy in normal and myopathic left ventricles.
PURPOSE To assess turbulent kinetic energy (TKE) within the left ventricle (LV) of healthy subjects using novel 4D flow magnetic resonance imaging (MRI) methods and to compare TKE values to those from a limited group of patients with a spectrum of dilated cardiomyopathy (DCM). MATERIALS AND METHODS 4D flow and morphological MRI data were acquired in 11 healthy subjects and 9 patients with dif...
متن کاملLeft ventricular kinetic energy as a marker of mechanical dyssynchrony in failing hearts with LBBB: a 4D flow CMR study
Background Left bundle branch block (LBBB) leads to dyssynchronous left ventricular (LV) contraction and relaxation which may contribute to LV dysfunction and ultimately heart failure. LBBB-related mechanical dyssynchrony often responds to cardiac resynchronization therapy (CRT). However, this therapy is expensive and the number of non-responders remains significant. Reliable functional markers...
متن کامل4D flow CMR detects progressive improvement in ventricular function following cardioversion of atrial fibrillation
Background Atrial fibrillation (AF) causes impairment of cardiac hemodynamics and substantial cardiovascular morbidity. While AF is difficult to assess with cardiac gated CMR, successful electrical cardioversion of chronic AF is often followed by a transient period of atrial stunning where absence of mechanical atrial contraction, similar to that seen in AF, persists despite reinstitution of si...
متن کاملTest-retest variability of left ventricular 4D flow cardiovascular magnetic resonance measurements in healthy subjects
BACKGROUND Quantification and visualisation of left ventricular (LV) blood flow is afforded by three-dimensional, time resolved phase contrast cardiovascular magnetic resonance (CMR 4D flow). However, few data exist upon the repeatability and variability of these parameters in a healthy population. We aimed to assess the repeatability and variability over time of LV 4D CMR flow measurements. ...
متن کاملStepped Spillway Performance: Study of the Pressure and Turbulent Kinetic Energy versus Discharge and Slope
In the present study, flow over flat and pooled stepped spillways was simulated three dimensionally. The VOF method and k- ε (RNG) turbulent model was used to simulate the flow over the stepped spillway. The results indicated that the numerical model was acceptably capable of simulating the flow over the pooled and flat stepped spillways for different discharges. Following that, the effect of d...
