Sensitivity and specificity of detection of mitral regurgitation was assessed by range-gated Doppler echocardiography. The degree of mitral regurgitation was also estimated by the depth and width of the regurgitant jet detected with Doppler and compared with that assessed by left ventriculography. Of 47 patients with an adequate Doppler study, 24 had no mitral regurgitation by ventriculography....

One of the most important roles of cardiovascular nuclear medicine in evaluating patients with coronary artery disease (CAD) is predicting patient outcome. Measurements of ventricular function obtained by radionuclide ventriculography play a key role in defining a patient's prognosis. Because ventricular function correlates well with the total extent of myocardial ischemic burden, data derived ...

Radionuclide ventriculography is an accepted method for diagnosing left ventricular aneurysms, but false-negative studies have been associated with a mural thrombus filling the left ventricular cavity. We describe a patient with a left ventricular aneurysm due to myocardial infarction whose aneurysm scintigraphically "disappeared" from serial radionuclide ventriculograms. This was documented ec...

To assess ventricular function in patients who have undergone cardiac transplantation, 247 radionuclide ventriculograms were performed on 94 patients. During the first three days after transplantation, 19% demonstrated left ventricular dysfunction and 41% showed isolated right ventricular dysfunction. In 95 cases, radionuclide ventriculography was performed within 24 hr of myocardial biopsy. A ...

Background: Ventriculography or Multigated Acquisition Scanning (MUGA) has been the gold standard for baseline and serial assessment of Left Ventricular Ejection Fraction (LVEF) cardiotoxicity since 1970. However, several modalities have proposed to substitute Ventriculography. This study aimed find out whether can still be considered monitor detect before, during, after administration chemothe...

In 80 male patients with coronary heart disease maximum diastolic pressure in the left ventricle (LVMDP) (usually the top of the a wave), and 'post a' end-diastolic pressure (LVEDP) before and 2 and 3 minutes after ventriculography were correlated to angiographic estimates of left ventricular function (aneurysm, ejection fraction (EF), and to lesions shown by selective coronary arteriography us...

Few studies have compared the use of low-contrast dose digital subtraction ventriculography with conventional ventriculography for quantitative assessment of both global and regional left ventricular function. Accordingly, 34 patients underwent conventional ventriculography using 36 ml of ionic contrast material and digital ventriculography (mask-mode) using 10 ml of contrast diluted in 10 ml o...

I IROIPOSE to deal with the surgical aspects of ventriculography, anid at the beginning I want to emphasize two principles whichi are fundamental first, the necessit-for a clinical diagnosis before ventriculography is attempted; second, the necessity of being prepared to perform at a momenit's notice any intracranial operation after ventriculographyl has been done. Ihe first principle ma) appea...
