Abstract
In defining the characteristic abnormalities of obstructive cardiomyopathy (OCM), the echocardiogram appears to offer an excellent method. We have used this technique in 22 adults presenting with this condition, and have compared the results of echocardiography with those taken from 17 normal subjects. All those with OCM had asymmetrical hypertrophy of the septum (meaning hypertrophy of the septum without proportional thickening of the posterior wall of the left ventricle); certain other facts were noted: an undilated left ventricular cavity, good systolic function, and indications of poor diastolic compliance. In addition, from the thickeness of the posterior wall and the movement of the mitral valve complex during systole, it has been possible to draw a distinction between the patients with and those without obstruction while they were all at rest. These results confirm that it is possible to identify obstructive cardiomyopathy and the frequently associated defects of ventricular function by an echocardiographic method.
