[Value of global ejection fractions based on the presence or absence of left ventricular dyskinesia. A comparison between contrast angiography and angioscintigraphy].
The total ejection fraction of the left ventricle is studied in 37 patients, most of them with coronary disease, according to two methods: contrast angiography in a single plane and angioscintigraphy (first passage and balanced), in order to compare the results according to the presence or the absence of dyskinesias. The two methods are performed in succession according to the usual views. The population is divided in two sub-groups according to the presence (17 patients) or the absence (20 patients) of segmental abnormalities. Segmental abnormalities are divided into 11 antero-apical aneurysms and 6 infero-posterior aneurysms. The correlations of the ejection fractions calculated according to the two methods and the two views, are usually satisfactory in the two sub-groups and especially as the parietal kinetics is homogeneous. In case of segmental abnormalities of the contraction, there are variations in the total ejection fractions depending on the technique and the views that are used, but the differences are not significant.
