[Comparison of two-dimensional echocardiography, angiocardioscintigraphy and cineventriculography in the study of left ventricular wall motion in ischemic cardiopathy].
Thirty-two patients with non acute myocardial infarction (inferior in twenty, anterior in ten, anterior and inferior in two) were studied with contrast left ventriculography, two-dimensional echocardiography and radionuclide angiography to assess left ventricular wall motion. We adopted the CASS criteria for the standard left ventriculography, and the Mayo Clinic classification for the echocardiographic study. Radionuclide angiography studies were obtained in left anterior oblique view; the images were evaluated with the use of Walsh-Hadamard transform; the left ventricle was divided in basal and apical septal, apical, posterolateral, posterobasal and two central segments. We tried to correlate the findings of the three techniques both for single segments and larger regions made of contiguous segments. Left ventricular angiography and two-dimensional echocardiography showed a fair concordance for both anterobasal and posterolateral left ventricular wall, whereas for the septal, apical and posterolateral regions contrast and radionuclide angiography had the best correlation. Compared to left ventricular angiography two-dimensional echocardiography shows better sensitivity than radionuclide angiography; the latter is more specific in defining left ventricular wall motion. The two non invasive techniques are therefore helpful in the evaluation of wall motion and their role is complementary.
