Linear and Nonlinear Viscoelastic Modeling of Aorta and Carotid Pressure-Area Dynamics Under In Vivo and Ex Vivo Conditions

ANNALS OF BIOMEDICAL ENGINEERING, 39(5), 1438–1456.

By: D. Valdez-Jasso n, D. Bia *, Y. Zocalo *, R. Armentano *, M. Haider n  & M. Olufsen n

author keywords: Viscoelasticity; Nonlinear elasticity; Arterial wall properties; Thoracic descending aorta; Carotid artery; Mathematical modeling
MeSH headings : Animals; Aorta; Aorta, Thoracic / physiology; Blood Pressure / physiology; Carotid Arteries / physiology; Elasticity; Female; Humans; Male; Models, Cardiovascular; Sheep
TL;DR: This study demonstrates that the proposed models can predict pressure–area dynamics and that model parameters can be extracted for further interpretation of biomechanical properties and indicates that optimal model selection depends on the artery type. (via Semantic Scholar)

2011 journal article

PREDICTING ARTERIAL FLOW AND PRESSURE DYNAMICS USING A 1D FLUID DYNAMICS MODEL WITH A VISCOELASTIC WALL

SIAM JOURNAL ON APPLIED MATHEMATICS, 71(4), 1123–1143.

By: B. Steele n, D. Valdez-Jasso*, M. Haider n  & M. Olufsen n

author keywords: 1D fluid dynamics model; viscoelastic constitutive equation; systemic arteries; finite element analysis
TL;DR: This paper combines a generalized viscoelastic model with a one-dimensional (1D) fluid dynamics model for the prediction of blood flow, pressure, and vessel area in systemic arteries. (via Semantic Scholar)

Linear and Nonlinear Viscoelastic Modeling of Ovine Aortic Biomechanical Properties under in vivo and ex vivo Conditions

2010 ANNUAL INTERNATIONAL CONFERENCE OF THE IEEE ENGINEERING IN MEDICINE AND BIOLOGY SOCIETY (EMBC), pp. 2634–2637.

By: D. Valdez-Jasso n, D. Bia *, M. Haider n , Y. Zocalo *, R. Armentano * & M. Olufsen n

MeSH headings : Animals; Aorta, Thoracic / pathology; Biomechanical Phenomena; Blood Pressure; Elasticity; Linear Models; Male; Models, Cardiovascular; Models, Statistical; Models, Theoretical; Nonlinear Dynamics; Sheep, Domestic; Stress, Mechanical; Transducers; Viscosity
TL;DR: It is concluded that the sigmoid nonlinear viscoelastic model best describes the biomechanical properties of ovine large arteries under both experimental conditions considered in this study. (via Semantic Scholar)

2008 journal article

Analysis of Viscoelastic Wall Properties in Ovine Arteries

IEEE TRANSACTIONS ON BIOMEDICAL ENGINEERING, 56(2), 210–219.

By: D. Valdez-Jasso n, M. Haider n , H. Banks n, D. Santana*, Y. German, R. Armentano *, M. Olufsen n

author keywords: Arterial wall properties; data analysis; mathematical modeling; mechanics; parameter estimation; viscoelasticity
MeSH headings : Algorithms; Animals; Arteries / physiology; Biomechanical Phenomena / physiology; Blood Pressure; Elasticity; Equipment Design; Male; Models, Cardiovascular; Nonlinear Dynamics; Sensitivity and Specificity; Sheep; Signal Processing, Computer-Assisted; Viscosity
TL;DR: Results reveal that elastic properties in both models vary across locations (smaller arteries are stiffer than larger arteries), and show that for all locations, the inclusion of viscoelastic behavior is important to capture pressure-area dynamics. (via Semantic Scholar)
