Radionuclide assessment of cardiac performance and myocardial perfusion in congestive cardiomyopathies. 1979

O Pachinger, and E Ogris, and H Sochor, and P Probst, and H Zasmeta, and F Kaindl

To determine the reliability of radionuclide techniques in the diagnosis of congestive cardiomyopathy (COCM), the function of the right ventricle (RV) and left ventricle (LV) was evaluated in 32 patients with COCM and 21 normal subjects using radionuclide angiography (first pass and gated blood pool scan) combined with quantitative 201 thallium (Tl) myocardial perfusion imaging. In COCM parameters of RV and LV performance were significantly reduced (p less than 0.01); regional wall motion analysis revealed a reduced radial shortening ability (p less than 0.05). 201 Tl distribution within the myocardium was not different between COCM and N; however, segmental 201Tl-uptake was significantly reduced (p less than 0.01). RV free wall was visualized on 201Tl scan in 80% of patients with COCM. There was no correlation between RV free wall visualization and RV hemodynamics. Thus these scintigraphic aspects provide an atraumatic and sensitive technique for the evaluation of patients with COCM.

D011877 Radionuclide Imaging The production of an image obtained by cameras that detect the radioactive emissions of an injected radionuclide as it has distributed differentially throughout tissues in the body. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph.

D005260 Female Females
D006321 Heart The hollow, muscular organ that maintains the circulation of the blood. Hearts
D006333 Heart Failure A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.
