Extraction of pulmonary vascular compliance, pulmonary vascular resistance, and right ventricular work from single-pressure and Doppler flow measurements in children with pulmonary hypertension: a new method for evaluating reactivity: in vitro and clinical studies.
BACKGROUND Current evaluation of pulmonary hypertension (PH) in children involves measurement of pulmonary vascular resistance (PVR); however, PVR neglects important pulsatile components. Pulmonary artery (PA) input impedance and ventricular power (VP) include mean and pulsatile effects and have shown promise as alternative measures of vascular function. Here we report the utility of pulsed-wav...

متن کاملEvaluation of the relationship between hepatic and cardiac iron overload with MRI T2* and carotid intima media thickness with Doppler ultrasound in beta thalassemia major patients
Background: Iron overload is caused early progression of atherosclerosis in beta thalassemia patients due to regular repeated blood transfusion. MRI T2* is a gold standard non-invasive method for detecting hepatic and cardiac iron overload. The aim of this study was the comparison of carotid intima media thickness (CIMT) in the patients and healthy control groups with Doppler ultrasound for ear...
متن کاملNon-invasive estimation of cardiac wall stress by using tissue doppler-echocardiography ultrasound images: People with coronary artery stenosis
In this study, a method for non-invasive estimation of stress on the heart wall in the diastole phase is presented using ultrasound echocardiography and tissue Doppler imaging. The aim of this study was to evaluate the stress on the heart wall as a pre-diagnosis to identify people with coronary artery stenosis. 29 patients with stenosis of more than 70%, 30 patients with stenosis of 50 to 7...
