A control system approach to subject specific prospective respiratory motion correction in cardiac MRI [PDF]

open access: yes, 2012
Includes bibliographical references.Respiratory motion of the heart is a problem for high-resolution cardiac MRI. Diaphragmatic navigator gating with a 5mm acceptance window is most commonly used to address this but has an inherently low respiratory ...

Analysis of three risk stratification systems in a Saudi population

open access: yesJournal of the Saudi Heart Association, 2017
Introduction: Coronary artery disease is the leading cause of death worldwide. Although there are a number of algorithms in use for determining the risk of coronary artery disease and thus predicting future cardiovascular events, the data available ...

Impact of tissue microstructure on a model of cardiac electromechanics based on MRI data [PDF]

open access: yes, 2011
Cardiac motion is a vital process as it sustains the pumping of blood in the body. For this reason motion abnormalities are often associated with severe cardiac pathologies.

Moving Domain Computational Fluid Dynamics to Interface with an Embryonic Model of Cardiac Morphogenesis [PDF]

open access: yes, 2013
Peristaltic contraction of the embryonic heart tube produces time- and spatial-varying wall shear stress (WSS) and pressure gradients (∇P) across the atrioventricular (AV) canal.

Left Atrial 4D Flow Characteristics in Patients with Atrial Fibrillation: Comparison with Healthy Controls and Associations with Left Atrial Remodelling and Contractile Health

open access: yesApplied Sciences
Left atrial (LA) four-dimensional (4D) flow quantification and strain may help predict stroke and thrombus formation in patients with atrial fibrillation (AF). We aimed to characterize flow changes in AF patients undergoing pulmonary vein isolation (PVI)

Imaging Techniques for the Assessment of Coronary Arteries in Diabetic Patients Undergoing PCI with Bioresorbable Vascular Scaffolds

open access: yesJournal of Interdisciplinary Medicine, 2017
Patients who suffer from diabetes mellitus and present coronary artery disease are at a higher risk of cardiovascular events. The coronary arteries of diabetic patients present a diffuse process of atherosclerosis with frequent distal involvement, being ...

Multimodality Imaging of Benign Primary Cardiac Tumor

open access: yes, 2022
Primary cardiac tumors (PCTs) are rare, with benign PCTs being relatively common in approximately 75% of all PCTs. Benign PCTs are usually asymptomatic, and they are found incidentally by imaging.
