Echocardiography in combined discrete and hypertrophic subaortic stenosis.
A 10-year-old boy with discrete subaortic stenosis had coexisting abnormal systolic anterior motion of the mitral valve, demonstrated by echocardiography, a sign normally taken as indicating the presence of idiopathic hypertrophic subaortic stenosis. Surgical removal of a fibromuscular diaphragm abolished the echocardiographic signs of discrete subaortic stenosis but abnormal systolic anterior ...
متن کاملEchocardiography in discrete subaortic stenosis.
Differentiating discrete subaortic stenosis (DSAS) from aortic valve stenosis (AVS) may be difficult, even at cardiac catheterization. Twenty-two patients with DSAS were studied echocardiographically and compared with 41 patients with AVS and 234 normal subjects. A ratio of left ventricular outflow tract to aortic root (LVOT: AO) < 0.80 determined LVOT narrowing in 19 of 22 DSAS patients. The a...
متن کاملIdiopathic hypertrophic subaortic stenosis.
ONE of the most characteristic clinical features of idiopathic hypertrophic subaortic stenosis (IHSS) is the striking variability in the intensity of the symptoms which accompany this disease. It has become clear recently that the severity of obstruction to left ventricular outflow is variable in IHSS and may be altered by a variety of physiological and pharmacological stimuli.' Alterations in ...

were assessed by echocardiographic recordings in 51 studies conducted on 37 patients with hypertrophic subaortic stenosis. The incidence and severity of echocardiographic findings in 19 patients treated with propranolol and in 18 not so treated showed no significant differences. Likewise these findings were unaltered by administration of propranolol in 12 patients who were studied both while th...
متن کاملCombined double chambered right ventricle and discrete subaortic stenosis.
Nine cases of combined double-chambered right ventricle (DCRV) and discrete subaortic stenosis (DSAS) are presented. A review of 1077 consecutively catheterized patients indicates an association of these two uncommon anomalies nine times greater than expected. One or both obstructive lesions may be hemodynamically significant and require surgery. Whenever DCRV or DSAS is suspected or identified...
