[Study of the left coronary artery by ultrasonic sectorial scanning].
Ultrasonic sectorial scanning was used to investigate 34 survivors of wide-spread anterior myocardial infarction and 25 normal subjects. The image of the proximal portion of the left coronary artery (LCA) was obtained from the parasternal access in 94.9% and the apical access in 96.6% of cases. Increased density of the arterial wall was demonstrated in all patients. A method of assessing the density of the left coronary artery through the comparison of image intensities obtained for the LCA with those of aortic walls and valve, is suggested.
