Abstract
When the clinical findings of aortic stenosis are present and a pressure gradient is demonstrated between the left ventricle and aorta, a discrete site of obstruction, generally amenable to surgical correction, has been assumed. The fallacy of this widely held concept is emphasized by the operative and hemodynamic findings in 3 patients described.
