Although subaortic stenosis of the left ventricular outflow tract was first described by Chevers1in 1832, its functional significance has been largely ignored. The inability to substantiate at surgery many preoperative diagnoses of aortic valvular obstruction based on the demonstration of a left ventricular-aortic gradient has stimulated interest in other causes of obstruction to flow. A precise differential diagnosis of supravalvular, valvular, and subvalvular outflow tract obstruction is critical in the selection of the appropriate surgical procedure. Until quite recently, stenotic...Bibliography1. Chevers N: Observations on the diseases of the orifice and valves of the aorta, Guy's Hosp. Reports, p. 387, 1842. Google Scholar2.
