Left ventricular dysfunction--bedside Valsalva manoeuvre.
Thirty-seven patients were evaluated before cardiac catheterisation by bedside physical examination, including Valsalva manoeuvre, to assess the value of the sphygmomanometrically determined arterial pressure responses during the Valsalva manoeuvre and to compare its sensitivity, specificity, and predictive accuracy in the detection of left ventricular dysfunction with that of the commonly used...
متن کاملAlterations in left ventricular volumes induced by Valsalva manoeuvre.
Five patients were studied with left ventriculography during different phases of the Valsalva manoeuvre. Small doses of contrast medium allowed adequate repetitive visualization of the left ventricle for volume calculation. During strain phase, the volume of the left ventricle decreased by nearly 50 per cent in each case, and stroke volume and cardiac output also dropped strikingly. Release of ...
متن کاملHigh myocardial 18F-FDG uptake after chemotherapy in the presence of left ventricular dysfunction as well as 3-month later with no left ventricular dysfunction
Diffusely increased glucose metabolic activity in the right and left ventricles using 2-deoxy-2-(F-18) fluoro-D-glucose positron emission tomography/computed tomography (18F-FDGPET/CT) and global left ventricular hypokinesia at echocardiography can be evident in acute myocarditis. But, there has been no case report that the ventricular 18F-FDGuptake remains unchanged even ...
متن کاملNon-invasive assessment of left ventricular response to Valsalva manoeuvre in normal and diabetic subjects using praecordial accelerocardiography.
The left ventricular response to the Valsalva manoeuvre was studied in 5 normal subjects (group 1), 6 diabetics without autonomic neuropathy (group 2), and 5 diabetics with autonomic neuropathy (group 3), using the maximum amplitude of the praecordial accelerocardiogram (DE) as a noninvasive index of left ventricular performance. During the Valsalva manoeuvre DE decreased in all 3 groups. In gr...
متن کاملComparison of Valsalva manoeuvre and exercise in echocardiographic evaluation of left ventricular outflow tract obstruction in hypertrophic cardiomyopathy.
AIMS Several methods are used to induce latent left ventricular outflow tract (LVOT) gradients in patients with hypertrophic cardiomyopathy (HCM). We compared LVOT gradients induced by Valsalva manoeuvre (VM) and exercise echocardiography (EE) in patients with HCM treated with percutaneous transluminal septal myocardial ablation (PTSMA). METHODS AND RESULTS Left ventricular outflow tract grad...
