Early Left Ventricular Involvement Detected by Cardiovascular Magnetic Resonance Feature Tracking in Arrhythmogenic Right Ventricular Cardiomyopathy: The Effects of Left Ventricular Late Gadolinium Enhancement and Right Ventricular Dysfunction

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background Left ventricular (LV) involvement is common in arrhythmogenic right ventricular cardiomyopathy (ARVC). We aim to evaluate LV involvement in ARVC patients by cardiovascular magnetic resonance feature tracking.

Will the real ventricular architecture please stand up? [PDF]

open access: yes, 2017
Ventricular twisting, essential for cardiac function, is attributed to the contraction of myocardial helical fibers. The exact relationship between ventricular anatomy and function remains to be determined, but one commonly used explanatory model is the ...

New experimental model of acute aqueductal blockage in cats: effects on cerebrospinal fluid pressure and the size of brain ventricles [PDF]

open access: yes, 2009
It is generally assumed that cerebrospinal fluid (CSF) is secreted in the brain ventricles, and so after an acute blockage of the aqueduct of Sylvius an increase in the ventricular CSF pressure and dilation of isolated ventricles may be expected. We have

Functional role of t-tubules on calcium transients in canine cardiac myocytes

open access: yesHeart and Mind, 2019
Background: A loss of t-tubules and alterations in ultrastructure occur in cultured ventricular myocytes. A similar alteration in t-tubules and ultrastructure is well documented under certain pathological conditions such as heart failure. We examined the

Using Systolic Local Mechanical Load to Predict Fiber Orientation in Ventricles

open access: yesFrontiers in Physiology, 2020
A simple rule adopted for myofiber reorientation in the ventricles is pursued by taking the microscopic branching network of myocytes into account.

Segmentation of the left ventricle of the heart in 3-D+t MRI data using an optimized nonrigid temporal model [PDF]

open access: yes, 2008
Modern medical imaging modalities provide large amounts of information in both the spatial and temporal domains and the incorporation of this information in a coherent algorithmic framework is a significant challenge.
