Journal ArticleDOI
Impairment of coronary flow reserve in aortic stenosis
Damien Garcia,Paolo G. Camici,Louis Gilles Durand,Kim Rajappan,Emmanuel Gaillard,Ornella Rimoldi,Philippe Pibarot +6 more
TL;DR: An explicit mathematical model formulated with a limited number of parameters that describes the effect of AS on left coronary inflow patterns and CFR is developed, combining the mathematical V(3) (ventricular-valvular-vascular) model with a new lumped-parameter model of coronary infow.
Journal ArticleDOI
Non-Invasive Determination of Left Ventricular Workload in Patients with Aortic Stenosis Using Magnetic Resonance Imaging and Doppler Echocardiography
Zahra Keshavarz-Motamed,Julio Garcia,Julio Garcia,Emmanuel Gaillard,Romain Capoulade,Florent Le Ven,Guy Cloutier,Lyes Kadem,Philippe Pibarot +8 more
TL;DR: Developing a lumped-parameter model to describe the ventricular-valvular-arterial interaction and to estimate the LV stroke work (SW), and introducing and validating a new index, the normalized Stroke Work (N-SW), to assess the global hemodynamic load imposed on the LV.
Journal ArticleDOI
Discrepancies between cardiovascular magnetic resonance and Doppler echocardiography in the measurement of transvalvular gradient in aortic stenosis: the effect of flow vorticity
Julio Garcia,Julio Garcia,Julio Garcia,Romain Capoulade,Florent Le Ven,Emmanuel Gaillard,Lyes Kadem,Philippe Pibarot,Eric Larose +8 more
TL;DR: Flow vorticity is one of the main factors responsible for MPG discrepancies between CMR and TTE, and two correction models were evaluated: based on the Gorlin equation and a multivariate regression model.
Journal ArticleDOI
Effect of coarctation of the aorta and bicuspid aortic valve on flow dynamics and turbulence in the aorta using particle image velocimetry
Zahra Keshavarz-Motamed,Zahra Keshavarz-Motamed,Julio Garcia,Julio Garcia,Emmanuel Gaillard,Nima Maftoon,Giuseppe Di Labbio,Guy Cloutier,Lyes Kadem +8 more
TL;DR: Findings of this study indicate that the presence of both a COA and a pathological aortic valve significantly alters hemodynamics in the aorta and thus might contribute to the progression of the disease in this region.
Journal ArticleDOI
Characterization of fracture toughness exhaustion in pig aorta.
TL;DR: The experiments reveal that aortic wall stiffness variations and fracture toughness exhaustion decreased as a function of loading cycles and can be modeled with exponential functions, suggesting the possibility to use fractures toughness exhaustion curves as a fatigue criterion.
