title: [Evaluation of post-infarction disorders of left ventricular contraction by echocardiography and scintigraphy of the cardiac cavities].
abstract: The comparison in 36 patients of two-dimensional echocardiography and scintigraphy of the cardiac cavities in the steady state with left cineventriculography selective for the evaluation of anomalies in left ventricular contraction post infarction shows good agreement between these techniques for the detection of major segmental anomalies, a higher sensitivity being found for echocardiography in dyskinesis. The overall rejection fraction calculated by two-dimensional echocardiography is correlated with the ejection fraction calculated in left cineventriculography (r = 0.57; p less than 0.001). The same is true of the overall ejection fraction obtained by cavitary scintigraphy (r = 0.62; p less than 0.01). The indices of residual myocardium in the anterior wall (IRM ant) and the posterior wall (IRM post) calculated in apical echographic section for the two cavities and in left cineventriculography (oblique anterior right) are also well correlated (IRM ant: r = 0.70 and p less than 0.001; IRM post: r = 0.46 and p less than 0.01). The determination of these parameters as well as the percentage of shortening of the left ventricular small axis measured by echocardiography TM, to the smallest value, permits a valid assessment of ventricular function and makes it possible to avoid coronaroventriculography when this function is too impaired.
