Estimation of Pulmonary Arterial Wave Reflection by Echo-Doppler: A Preliminary Study in Dogs With Experimentally-Induced Acute Pulmonary Embolism [PDF]

open access: yesFrontiers in Physiology, 2021
Background: Pulmonary arterial (PA) wave reflection provides additional information for assessing right ventricular afterload, but its applications is hampered by the need for invasive pressure and flow measurements.

Wave reflection quantification analysis and personalized flow wave estimation based on the central aortic pressure waveform [PDF]

open access: yesFrontiers in Physiology, 2023
Pulse wave reflections reflect cardiac afterload and perfusion, which yield valid indicators for monitoring cardiovascular status. Accurate quantification of pressure wave reflections requires the measurement of aortic flow wave.

Mechanisms of Aortic Flow Deceleration and the Effect of Wave Reflection on Left Ventricular Function [PDF]

open access: yesFrontiers in Physiology, 2020
Increased wave reflection is an independent predictor of cardiovascular events, possibly due to effects on left ventricular (LV) function. We investigated the relationship between reflected waves in early systole, the forward decompression wave in mid ...

Measurement of Pulmonary Artery Wave Reflection Before and After Mitral Valvuloplasty in Canine Patients With Pulmonary Hypertension Caused by Myxomatous Mitral Valve Disease [PDF]

open access: yesFrontiers in Veterinary Science, 2021
Background: Pulmonary arterial wave reflection provides novel information about pulmonary artery hemodynamics in pulmonary hypertension (PH). PH is common in dogs with myxomatous mitral valve disease (MMVD), though research examining the relationship ...

Acute systemic inflammation reduces both carotid and aortic wave reflection in healthy adults [PDF]

open access: yesPhysiological Reports, 2019
Acute inflammation increases the risk of cardiac and cerebrovascular events, possibly related to alterations in the hemodynamic load. Wave reflection at the aorta and carotid provides insight into downstream vascular changes and hemodynamic load at the ...

Changes in the Pulmonary Artery Wave Reflection in Dogs with Experimentally-Induced Acute Pulmonary Embolism and the Effect of Vasodilator [PDF]

open access: yesAnimals, 2021
Pulmonary hypertension (PH) is a complex syndrome that has been frequently diagnosed in dogs and humans and can be detected by Doppler echocardiography and invasive catheterization. Recently, PAWR attracts much attention as a noninvasive approach for the

Racial Differences in Left Ventricular Mass and Wave Reflection Intensity in Children [PDF]

open access: yesFrontiers in Pediatrics, 2020
The burden of heart failure is disproportionately higher in African Americans, with a higher prevalence seen at an early age. Examination of racial differences in left ventricular mass (LVM) in childhood may offer insight into risk for cardiac target ...

ADE-FDTD method for study of two-dimensional electromagnetic wave propagation in lossy lorentz medium [PDF]

open access: yesMATEC Web of Conferences, 2020
In order to study the reflection of electromagnetic wave in Lorentz medium layer, the finite difference time domain method of auxiliary differential equation (ADE-FDTD) is used to derive the difference formula of two-dimensional TM wave propagating in ...
