Abstract
The echocardiographic findings of three patients with discrete subaortic stenosis associated with infective endocarditis are reported. This disorder was suspected because of early systolic aortic valve partial closure followed by a fine fluttering throughout systole in each case. Narrowing of the left ventricular outflow tract as judged by the left ventricular outflow tract/aortic root ratio was of limited diagnostic value because the presence of echoes of aortic vegetations at this level in two cases prevented accurate measurement of the outflow tract. This study suggests that a careful echocardiographic study may detect discrete subaortic stenosis in the presence of aortic valve endocarditis. Thus, whenever left ventricular outflow obstruction is associated with infective endocarditis, early systolic aortic valve partial closure followed by a fine fluttering throughout systole should be carefully sought
