Aortic length measurements for pulse wave velocity calculation: manual 2D vs automated 3D centreline extraction
BACKGROUND Pulse wave velocity (PWV) is a biomarker for the intrinsic stiffness of the aortic wall, and has been shown to be predictive for cardiovascular events. It can be assessed using cardiovascular magnetic resonance (CMR) from the delay between phase-contrast flow waveforms at two or more locations in the aorta, and the distance on CMR images between those locations. This study aimed to i...
متن کاملCentral aortic pressure influences pulse wave velocity.
Central Aortic Pressure Influences Pulse Wave Velocity To the Editor: The study reported by Lantelme and colleagues1 suggests that increasing heart rate is independently associated with higher aortic pulse wave velocity (PWV). We are concerned that the authors of this study have neither addressed the impact of central aortic pressure changes on PWV nor the presence of potential bias in their st...
متن کاملLocation of a reflection site is elusive: consequences for the calculation of aortic pulse wave velocity.
Aortic pulse wave velocity (PWV), a measure of aortic stiffness, is an important indicator of cardiovascular risk. Derivation of PWV from uncalibrated proximal aortic or carotid pressure alone has practical advantages. However, when the time of return of the reflected wave, (Delta)t, is used to calculate PWV, inaccurate data are obtained. With aging PWV increases but (Delta)t hardly decreases, ...
متن کاملValidating a new oscillometric device for aortic pulse wave velocity measurements in children and adolescents.
BACKGROUND Pulse wave velocity (PWV) is an indicator of aortic stiffness and a predictor of cardiovascular risk. Applanation tonometry (e.g., SphygmoCor) is a well-established method to measure aortic PWV (aPWV). The Vicorder, a new oscillometric device, has not been validated in children and adolescents. METHODS We performed intra- and interobserver repeatability studies in 14 individuals us...
متن کاملRobust segmentation methods with an application to aortic pulse wave velocity calculation
Aortic stiffness has proven to be an important diagnostic and prognostic factor of many cardiovascular diseases, as well as an estimate of overall cardiovascular health. Pulse wave velocity (PWV) represents a good measure of the aortic stiffness, while the aortic distensibility is used as an aortic elasticity index. Obtaining the PWV and the aortic distensibility from magnetic resonance imaging...
