Axial left ventriculography in discrete subaortic stenosis.
Left ventricular angiograms of six children were reviewed, and it was found that those obtained in axial (long axial oblique and hepatoclavicular) projections enhanced precision in the diagnosis of subvalvular aortic stenosis. The methods for obtaining these views are described, and the results presented. Axial views are never inferior to standard (posteroanterior, lateral, and right anterior oblique) projections, and are usually superior to them, especially when there are associated lesions, such as ventricular septal defects, left-sided obstructive lesions, and patent ductus arteriosus.
