Types of Angiopathy in Experimental Autoimmune Disease in Rats [PDF]
, 2017 The purpose and objectives of this work were to study the nature of the heart, lungs and kidneys angiopathy in rats with a model of systemic autoimmune disease, carrying out comparisons of the results with extravasal morphological manifestations of the ...

The living aortic valve: From molecules to function. [PDF]
, 2014 The aortic valve lies in a unique hemodynamic environment, one characterized by a range of stresses (shear stress, bending forces, loading forces and strain) that vary in intensity and direction throughout the cardiac cycle.

Outflow Tract Formation—Embryonic Origins of Conotruncal Congenital Heart Disease
Journal of Cardiovascular Development and Disease, 2021 Anomalies in the cardiac outflow tract (OFT) are among the most frequent congenital heart defects (CHDs). During embryogenesis, the cardiac OFT is a dynamic structure at the arterial pole of the heart.

Initiation and dynamics of a spiral wave around an ionic heterogeneity in a model for human cardiac tissue [PDF]
, 2013 In relation to cardiac arrhythmias, heterogeneity of cardiac tissue is one of the most important factors underlying the onset of spiral waves and determining their type.

Numerical simulation of electrocardiograms for full cardiac cycles in healthy and pathological conditions [PDF]
, 2015 This work is dedicated to the simulation of full cycles of the electrical activity of the heart and the corresponding body surface potential. The model is based on a realistic torso and heart anatomy, including ventricles and atria.

Identification of weakly coupled multiphysics problems. Application to the inverse problem of electrocardiography [PDF]
, 2015 This work addresses the inverse problem of electrocardiography from a new perspective, by combining electrical and mechanical measurements. Our strategy relies on the defini-tion of a model of the electromechanical contraction which is registered on ECG ...
