Myocardial Blood Flow and Inflammatory Cardiac Sarcoidosis
JACC: Cardiovascular Imaging, 2017 This study sought to evaluate the effects of inflammatory sarcoid disease on coronary circulatory function and the response to immune-suppressive treatment.Although positron emission tomography assessment of myocardial inflammation is increasingly applied to identify active cardiac sarcoidosis, its effect on coronary flow and immune-suppressive ...

Motion estimation of vortical blood flow within the right atrium in a patient with atrial septal defect [PDF]
, 2007 Copyright © 2007 IEEEPatients with an atrial septal defect (ASD) have a left to right shunt with associated complications. Currently, various imaging modalities, including echocardiography and invasive cardiac catheterization, are utilized in the ...

Vasopressin impairs brain, heart and kidney perfusion: an experimental study in pigs after transient myocardial ischemia [PDF]
, 2008 Introduction: Arginine vasopressin (AVP) is increasingly used to restore mean arterial pressure (MAP) in low-pressure shock states unresponsive to conventional inotropes. This is potentially deleterious since AVP is also known to reduce cardiac output

Echocardiographic Assessment of Atrial Function: From Basic Mechanics to Specific Cardiac Diseases
Journal of Cardiovascular Development and Disease, 2022 The left and right atria serve as buffer chambers to control the flow of venous blood for ventricular filling. If an atrium is absent, blood does not flow effectively into the ventricle, leading to venous blood retention and low cardiac output.

Replacing the Transfusion of 1-2 Units of Blood with Plasma Expanders that Increase Oxygen Delivery Capacity: Evidence from Experimental Studies. [PDF]
, 2014 At least a third of the blood supply in the world is used to transfuse 1-2 units of packed red blood cells for each intervention and most clinical trials of blood substitutes have been carried out at this level of oxygen carrying capacity (OCC ...

Reduced reactive hyperemia may explain impaired flow‐mediated dilation after on‐pump cardiac surgery
Physiological Reports, 2017 In previous studies, Flow Mediated Dilation (FMD) was used to study the effect of cardiac surgery on endothelial function. This study investigated the effect of on‐pump cardiac surgery on FMD and reactive hyperemia.
