Journal ArticleDOI
Arterial Stiffness Assessment by Shear Wave Elastography and Ultrafast Pulse Wave Imaging: Comparison with Reference Techniques in Normotensives and Hypertensives.
Louise Marais,Louise Marais,Mathieu Pernot,Hakim Khettab,Mickael Tanter,Emmanuel Messas,Mustapha Zidi,Stéphane Laurent,Pierre Boutouyrie +8 more
TL;DR: Shear wave speed in the carotid anterior appeared to be the best candidate to evaluate arterial stiffness from ultrafast imaging and increased with blood pressure throughout the cardiac cycle and did not differ between normotensive participants and patients with essential hypertension when compared at similar blood pressures.
Journal ArticleDOI
Evaluation of arterial stiffness by finger-toe pulse wave velocity: optimization of signal processing and clinical validation.
TL;DR: Selecting the maximum of the second derivative algorithm for detecting the foot of the pressure waveform, and combining it with an optimized signal processing chain, improved the accuracy of ft-PWV measurement in the current population sample.
Journal ArticleDOI
Deep Vascular Phenotyping in Patients With Renal Multifocal Fibromuscular Dysplasia.
Rosa Maria Bruno,Louise Marais,Hakim Khettab,Aurélien Lorthioir,Michael Frank,Xavier Jeunemaitre,Stéphane Laurent,Stéphane Laurent,Pierre Boutouyrie,Pierre Boutouyrie,Michel Azizi,Michel Azizi +11 more
TL;DR: Nonclinically affected large- and medium-sized arteries in patients with multifocal renal fibromuscular dysplasia exhibit a cluster of diffuse alterations in smooth muscle cell function, arterial geometry, wall characteristics, and mechanical properties.
Journal ArticleDOI
Silicon photonics-based laser Doppler vibrometer array for carotid-femoral pulse wave velocity (PWV) measurement
Yanlu Li,Louise Marais,Hakim Khettab,Zhiheng Quan,Soren Aasmul,Rob Leinders,Ralf Schüler,Padraic E. Morrissey,Stephen E. Greenwald,Patrick Segers,Michael Vanslembrouck,Rosa Maria Bruno,Pierre Boutouyrie,Peter O'Brien,Mirko De Melis,Roel Baets +15 more
TL;DR: It is shown that it is possible to identify reliable fiducial points for PTT calculation using the maximum of the 2nd derivative algorithm in LDV-based signals, comparable to those obtained by the reference technique, applanation tonometry.
Journal ArticleDOI
Diameter and thickness-related variations in mechanical properties of degraded arterial wall in the rat xenograft model.
TL;DR: The proposed approach revealed correlations of ultimate stress and material parameters of aneurysmal aortas with outer diameter and thickness, suggesting that wall thickness and diameter may be indicators of rupture risk in the rat xenograft model.
