INTRODUCTION Epicardial fat volume (EFV) has been reported to correlate with the severity of coronary artery disease (CAD). Pericardial fat volume (PFV) has recently been reported to be strongly associated with CAD severity and presence. We aimed to investigate the relationship between EFV and PFV with severity of coronary artery stenosis in patients undergoing 64-slice multi-slice computed tom...

OBJECTIVE The findings of magnetic resonance and x-ray angiography were compared for assessment of coronary artery stenosis in this validation study. BACKGROUND Magnetic resonance angiography of the coronary arteries has recently been described, but there has been no comparison with x-ray angiography of localisation or assessment of important characteristics of coronary stenosis. METHODS A ...

Background: Grading stenosis based on morphology of the dural sac on MRI rather than surface measurements defines stenosis in various topics. To study the relations between the grading stenosis and the severity of clinical symptoms of spinal stenosis in patients diagnosed with lumbar spinal canal stenosis (LSCS). Methods: Patients diagnosed with lumbar spinal stenosis who were candidate for sur...

OBJECTIVE To determine the prognosis of supravalve aortic stenosis into early adult life and the factors affecting this prognosis. DESIGN 81 patients with supravalve aortic stenosis were followed for a median duration of 8.3 (range 1 to 29) years. PATIENTS 40 patients (49.4%) had Williams' syndrome, 18 (22.2%) familial supravalve aortic stenosis, 18 (22.2%) sporadic supravalve aortic stenos...

In a search for an indirect estimate of severity, data from 40 patients with pure aortic stenosis have been analyzed. Calculated aortic valvular areas ranged from 0.5 cm2 to 2.4 cm.2 Both aortic systolic upstroke time and the rate of aortic pressure rise were significantly altered by aortic stenosis; neither permitted reliable estimates of severity of the stenosis. An estimate of arterial compl...

PURPOSE This paper proposes a model to measure the cardiac output and stroke volume at different aortic stenosis severities using a fluid-structure interaction (FSI) simulation at rest and during exercise. METHODS The geometry of the aortic valve is generated using echocardiographic imaging. An Arbitrary Lagrangian-Eulerian mesh was generated in order to perform the FSI simulations. Pressure ...
