Accuracy of flow volume estimation in the dilated aorta using 4D flow MRI: a pulsatile phantom study.

Aortic dilatation is a severe pathology that increases the risk of rupture and its hemodynamics could be accurately assessed by using the 4D flow cardiovascular magnetic resonance (CMR) technique but flow assessment under complex flow patterns require validation. The aim of this work was to develop an in vitro system compatible with CMR to assess the accuracy of volume flow measurements in dilated aortas. Approach.

Reference intervals of aortic pulse wave velocity assessed with an oscillometric device in healthy children and adolescents from Argentina.

Age-related reference intervals (RIs) of aortic pulse wave velocity (Ao-PWV) obtained from a large healthy population are lacking in South America. The aims of this study were to determine Ao-PWV RIs in a cohort of healthy children and adolescents from Argentina and to generate year-to-year percentile curves. Ao-PWV was measured in 1000 healthy subjects non-exposed to traditional cardiovascular risk factors (Age: 10-22 y.

Arterial Stiffness in a Rural Population of Argentina: Pilot Study.

Introduction: Aortic stiffness evaluated through pulse wave velocity (PWV) measurement is nowadays accepted as a reliable parameter to estimate cardiovascular risk. However the data about arterial stiffness in South America come from urban populations.

Aims: To determine the relationship between PWV changes and ageing and to identify the rate of change in each decade of life.

Reference values of pulse wave velocity in healthy people from an urban and rural argentinean population.

In medical practice the reference values of arterial stiffness came from multicenter registries obtained in Asia, USA, Australia and Europe. Pulse wave velocity (PWV) is the gold standard method for arterial stiffness quantification; however, in South America, there are few population-based studies. In this research PWV was measured in healthy asymptomatic and normotensive subjects without history of hypertension in first-degree relatives.
