Echocardiography identified abnormal echo patterns correlating well with radiological, surgical, or pathological evidence of valve calcification, providing a reliable indication of aortic stenosis.
Observational
Does echocardiography accurately detect aortic valve calcification and stenosis compared to radiological, surgical, or pathological evidence?
Echocardiography can reliably indicate aortic stenosis by detecting abnormal echo patterns that correlate with valve cusp calcification.
Echocardiography studies of the normal aortic valve and the valve involved by disease were accomplished with pulsed ultrasonic techniques and extended recording by oscilloscope record camera. In aortic stenosis, normal cusp architecture was obscured by a thick multilayered echo pattern usually heavier than that of the aortic wall. Occasionally, these echoes persisted through systole and diastole, in others, a systolic break occurred. A good correlation existed between this abnormal echo pattern and radiological, surgical, or pathological evidence of valve cusp calcification which, in the absence of normal systolic cusp motion, is a reliable indication of aortic stenosis.
Gramiak et al. (Wed,) conducted a observational in Aortic stenosis. Echocardiography was evaluated on Correlation of abnormal echo pattern with valve cusp calcification. Echocardiography identified abnormal echo patterns correlating well with radiological, surgical, or pathological evidence of valve calcification, providing a reliable indication of aortic stenosis.
