Evaluation of the intraventricular hemodynamics of patients with left ventricular dysfunction via vector flow mapping [PDF]

Frontiers in Cardiovascular Medicine
BackgroundVorticity, measured via new vector flow mapping (VFM), a quantitative marker of vortex dynamics, can reflect hemodynamic changes more sensitively, potentially offering complementary information to conventional echocardiographic indices of ...

Mean and Variability of Lipid Measurements and Risk for Development of Subclinical Left Ventricular Diastolic Dysfunction [PDF]

Diabetes & Metabolism Journal, 2022
Background Subclinical left ventricular diastolic dysfunction (LVDD) is an emerging consequence of increased insulin resistance, and dyslipidemia is one of the few correctable risk factors of LVDD. This study evaluated the role of mean and visit-to-visit

Diastolic and Systolic Longitudinal Myocardial Velocities of Healthy Racing Pigeons (Columba livia f. domestica) Measured by Tissue Doppler Imaging

Veterinary Sciences, 2021
Tissue Doppler imaging (TDI) is a noninvasive sonographic method of acquiring and quantifying myocardial velocities. This technique is used in human and small animal medicine to diagnose cardiac diseases.

The impact of cardiac loading on a novel metric of left ventricular diastolic function in healthy middle‐aged adults: Systolic–diastolic coupling

Physiological Reports, 2021
Aims Left ventricular (LV) restoring forces are primed by ventricular deformation during systole and contribute to cardiac relaxation and early diastolic suction.

Effects of Early Myocardial Postnatal Maturation on Tolerance to Atrial Tachycardia With Altered Loading Conditions: An in vivo Swine Model

Frontiers in Pediatrics, 2020
Post-natal maturation of the myocardium starts shortly after birth and could affect how clinicians should provide hemodynamic support during this transition.

Numerical study of hemodynamics after stent implantation during the cardiac cycle

Journal of Mechanical Engineering and Sciences, 2021
The descending aortic aneurysm is one of the most catastrophic cardiovascular emergencies resulting in high mortality worldwide. Clinical observations have pointed out that stent implantation in the sick aorta should probably allow stabilization of the ...

Color Flow Doppler Echocardiography in Healthy Racing Pigeons (Columba livia f. domestica) and the Evidence of Physiological Blood Flow Vortex Formations

Veterinary Sciences, 2020
In avian medicine, Doppler sonographic techniques are used to visualize and estimate blood flow in the heart. In the literature there is a lack of standardized studies of the use of color Doppler flow on healthy avian species.
