We sectioned a series of hearts in a manner similar to that seen on angiographic axial views. A correlation with normal angiograms to identify the anatomic components of the four cardiac chambers showed that the components of the normal cardiac anatomy can be identified accurately through axial angiography in a manner not show previously.
The anatomic abnormalities observed by cineangiographic axial techniques of 12 patients with tetralogy of Fallot were correlated with anatomic details noted at necropsy. Right ventricular angiograms made in the right anterior oblique view best demonstrated the severity and type of infundibular obstruction and also permitted differentiation of the perimembranous, infundibular muscular and subarterial types of ventricular septal defects. The degree of aortic overriding was best displayed in the long-axis view. Comparison of the intracardiac anatomy of each postmortem specimen with the respective premortem cineangiogram has provided further clarification of the angiographic anatomy displayed by these axial techniques.
A case of X/XXX mosaicism in a neonate with dysgenetic gonads is presented because of the rarity of the X/XXX karyotype and the presence of dysgenetic ovaries and congenital heart anomalies. We suggest that the X/XXX mosaicism may not have a protective effect on the gonads as does X/XX mosaicism in some cases.
The authors present a case of disseminated emboli originating in a thrombotic, aneurysmal ductus arteriosus in a neonate. In a critically ill neonate, the arteriographic appearance of ectatic, elongated, and tortuous vessels proximal to a stenotic segment is suggestive of multiple arterial emboli.

This case report attempts to document the reversibility of advanced hepatic anatomical and clinical alterations compatible with advanced hepatic cirrhosis that occasionally develop in patients with jejunoileal bypass performed for morbid obesity. The advanced stage of this complication can be fatal unless the intestinal continuity is returned to normal.
