Delayed improvement of left ventricular contractile function in the setting of acute ischemia followed by reperfusion ("stunned myocardium") has been observed in a number of clinical scenarios, and may have important clinical implications. At present, there are no widely accepted techniques available to demonstrate its presence. We report a case in which a rest 99mTc-sestamibi scan performed 12...

Eighteen infants and children with typical congenital hydranencephaly were studied by pneumoen cephalography, water-soluble contrast ventriculography, and cisternography (radioisotope or metri zamide). Pneumoencephalography and ventriculography suggested that the aqueduct was obstructed or markedly stenotic in all cases. Cisternography demonstrated blocks at the aqueduct and at the level of the...

The filling patterns of a negative contrast material (air), a positive contrast water soluble material (Conray), and a positive contrast water insoluble material (Myodil) were examined in 60 normal ventriculograms. Using a scoring system developed for this study, Conray was found effective for outlining the ipsilateral (injected) lateral ventricle, the third ventricle, the aqueduct of Sylvius, ...

Thirty one patients with multiple ventricular septal defects were studied by cross sectional echocardiography, conventional pulsed and continuous wave Doppler, colour flow imaging, and left ventriculography to determine the relative diagnostic benefits and pitfalls of each technique. The patients studied had a wide range of congenital heart defects with 19 patients having isolated multiple vent...

OBJECTIVE To examine how exercise testing on background medical treatment affects the ability of the test to predict prognostically important patterns of coronary anatomy in patients with a high clinical probability of coronary artery disease but who are well controlled on medication. DESIGN Prospective study. SETTING Regional cardiothoracic centre and referring district general hospital. ...

Objective: To assess the accuracy of echocardiography with Simpson’s apical biplane method in screening for left ventricular systolic dysfunction (LVSD) in patients six months after acute myocardial infarction (AMI) as compared with radionuclide ventriculography by assessing the proportion of clinically significant errors that occur with echocardiography. Design: Comparison of results of echoca...

at Penylvania State U niersity on Feruary 3, 2013 /eurheartrdjournals.org/ Aims Increased plasma concentrations of B-type natriuretic peptide (BNP) and its precursor (proBNP) provide important prognostic information in patients presenting with acute coronary syndromes. Although a majority of these patients undergo early invasive assessment, the effects of coronary angiography per se on plasma B...
