Tissue structure and ventricular wall mechanics.
Considering that the left ventricle is a thick-walled body that maintains its volume while reducing intracavitary volume by two thirds, it should come as no surprise that the ventricular wall thickens during systole and that there is a transmural gradient in wall thickening. Wall thickening on the inner wall may exceed values of 40% measured by a variety of techniques. These values far exceed t...
متن کاملExperimental cerebral vasospasm arterial wall mechanics and connective tissue composition.
The elastic properties of the basilar artery were studied in control and treated dogs in which 3 ml of blood was injected intracisternally. Vascular specimens were resected transclivally as cylindrical segments and their external diameters were measured in vitro in the pressure range from 0 mm Hg to 250 mm Hg in the active condition of smooth muscle in Krebs-Ringer solution and in the passive c...
متن کاملEngineering mechanics for successive states in canine left ventricular myocardium. I. Cavity and wall geometry.
The relations between end-diastolic (D) and end-systolic (S) fiber angles (a) and sarcomere lengths (s) have been previously studied at different sites in canine left ventricular myocardium. However, no postulates have been advanced for predicting a and s in successive states of the ejection cycle (D or S) or at different sites in one state when the semimajor (Z) and semiminor (R) axes of the w...
متن کاملQuantifying passive myocardial stiffness and wall stress in heart failure patients using personalized ventricular mechanics
Background Heart failure (HF) patients present with a spectrum of phenotypes, including preserved ejection fraction (HFpEF) and reduced EF (HFrEF). The underlying mechanisms of HFpEF and HFrEF may be related to mechanical factors such as stiffness and stress. This study aimed to quantify passive mechanical properties in HFrEF and HFpEF patients using personalised left ventricular (LV) biomechan...

Phvsiol. 12): H379-H390, 1982.-Significant differences between kpicardial and endocardial systolic stress in the wall of the left ventricle (LV) have been predicted by various models of LV mechanics. Yet a model incorporat...
