Aortic pulse wave velocity assessment in CMR: a novel method for transit time estimation
نویسندگان
چکیده
Background Aortic pulse wave velocity (PWV) is considered as the “gold standard” measurement of arterial stiffness and is commonly calculated as the ratio between the distance separating two locations along the artery and the transit time (Δt) needed for the pressure or velocity wave to cover this distance. PWV is increasingly assessed by means of cardiovascular magnetic resonance (CMR). Our goal was evaluate the efficiency of a novel method for Δt estimation, based on the principle of group delay (TT-GD method).

Measurement of aortic pulse wave velocity in CMR: comparison of transit time estimators
Background CMR is increasingly used for measuring aortic arch PWV (arch-PWV) by using accurate aortic length and transit time between flow waves. If robust aortic length measurement is an obvious strength of CMR thanks to many 3D imaging approaches available, Δt measurement remains a major challenge. Consequently, different methods have been previously described to estimate the Δt using CMR, bu...
متن کاملComparison of an Oscillometric Method with Cardiac Magnetic Resonance for the Analysis of Aortic Pulse Wave Velocity
OBJECTIVES Pulse wave velocity (PWV) is the proposed gold-standard for the assessment of aortic elastic properties. The aim of this study was to compare aortic PWV determined by a recently developed oscillometric device with cardiac magnetic resonance imaging (CMR). METHODS PWV was assessed in 40 volunteers with two different methods. The oscillometric method (PWVOSC) is based on a transfer f...
متن کاملClinical value of pulse wave velocity: a promising marker for arterial stiffness
recent non-invasive approach to measure PWV is by using cardiovascular magnetic resonance imaging (CMR). CMRderived PWV is more reliable, not limited by imaging planes, and CMR offers more possibilities regarding cardiovascular imaging (i.e. aortic anatomy, plaque visualisation and characterisation, cardiac function, carotid patency). Specifically regarding PWV, CMR also allows measurement of r...

BACKGROUND Transgenic mouse models are increasingly used to study the pathophysiology of human cardiovascular diseases. The aortic pulse wave velocity (PWV) is an indirect measure for vascular stiffness and a marker for cardiovascular risk. RESULTS This study presents a cardiovascular magnetic resonance (CMR) transit time (TT) method that allows the determination of the PWV in the descending ...
متن کاملBramwell-Hill modeling for local aortic pulse wave velocity estimation: a validation study with velocity-encoded cardiovascular magnetic resonance and invasive pressure assessment
BACKGROUND The Bramwell-Hill model describes the relation between vascular wall stiffness expressed in aortic distensibility and the pulse wave velocity (PWV), which is the propagation speed of the systolic pressure wave through the aorta. The main objective of this study was to test the validity of this model locally in the aorta by using PWV-assessments based on in-plane velocity-encoded card...
