Left ventricular twist is load-dependent as shown in a large animal model with controlled cardiac load

BACKGROUND Left ventricular rotation and twist can be assessed noninvasively by speckle tracking echocardiography. We sought to characterize the effects of acute load change and change in inotropic state on rotation parameters as a measure of left ventricular (LV) contractility. METHODS Seven anesthetised juvenile pigs were studied, using direct measurement of left ventricular pressure and vo...

Ventricular response to a pressure load. Left ventricular function curves in intact animal.

• The normal left ventricular response to progressive proximal aortic obstruction has three phases: (1) a phase of complete compensation in which, following transitory elevations of end-diastolic ventricular pressure (EDVT) and end-diastolic ventricular volume (EDVV), the peak ventricular pressure (PVP) is increased and cardiac output is maintained though end-diastolic ventricular pressure and ...

Low Load Twist Compression Study

IRDI – An Overview IRDI (Industrial Research + Development Institute) is located in Midland, Ontario, Canada. IRDI was founded in 1992 by two local business entrepreneurs as an industry-driven research institute. IRDI moved to its current location in 1995, and is still housed within this industrial-scale 55,000 square foot facility that was acquired by Georgian College of Applied Arts and Techn...

Left ventricular strain and peak systolic velocity: responses to controlled changes in load and contractility, explored in a porcine model

BACKGROUND Tissue velocity echocardiography is increasingly used to evaluate global and regional cardiac function. Previous studies have suggested that the quantitative measurements obtained during ejection are reliable indices of contractility, though their load-sensitivity has been studied in different settings, but still remains a matter of controversy. We sought to characterize the effects ...

Load Controlled Fatigue of AZ31B

With the expanding demand on application of magnesium alloys in automotive and aerospace industries, robust methods in fatigue characterization of commercially available magnesium alloys with high specific strength is anticipated. In this paper, rotating bending load controlled tests has been studied on specimens machined from an extrusion piece of AZ31B. Due to asymmetric and anisotropic behav...
