Supports mitral valve motion assessment for HSS diagnosis; leaves open validation against modern noninvasive standards.
Does echocardiography accurately diagnose and assess hemodynamic severity in patients with suspected or known hypertrophic subaortic stenosis?
Echocardiographic assessment of anterior mitral leaflet motion is highly sensitive and specific for diagnosing hypertrophic subaortic stenosis and correlates with the severity of left ventricular outflow tract obstruction.
Shah et al. (1971) studied this question.
