RESUMO
Left ventricular ejection fractions of 31 patients determined from first-pass or single-pass radionuclide angiography from the anterior position using a microcomputer system and floppy disc were compared to angiographic catheterization data obtained from the right anterior oblique position. This study demonstrated a good correlation with r = 0.91. To our knowledge, this is the first report of comparative first-pass left ventricular ejection fraction data and contrast angiography using a microcomputer system and a floppy disc.

Two autopsy-proved cases are presented of a rare form of congenital heart disease, anatomically corrected malposition (S, D, L). Anatomically corrected malposition means that despite the abnormal relationship between the great arteries, the aorta arises nonetheless above the anatomically left ventricle and the pulmonary artery originates above the anatomically right ventricle. (S, D. L) briefly indicates the segmental set or combination: situs solitus of viscera and atria (S), ventricular D-loop (D), AND L-MALPOSITION OF THE GREAT ARTERIES (L). These are the first cases of anatomically corrected malposition (ACM) in whom the presence of a subaortic muscular conus only has been documented pathologically. This established that ACM can occur with a subaortic conus, as well as with a bilateral conus. From the diagnostic standpoint, the distributions or epicardial courses of the coronary arteries are recommended as a helpful approach to ventricular identification. This diagnostic method has widespread angiocardiographic and surgical applications. Symbolic terminology, exemplified by anatomically corrected malposition (S, D. L) is brief and accurate. This approach may conveniently be applied to many other forms of comples congenital heart disease, and it considerably facilitates computer data processing.
