Key result
Ultrasoundcardiography of the mitral ring in 25 normal subjects demonstrated a remarkably constant movement of 1.6 ± 0.4 cm, with deviations from this normal pattern seen in heart disease.
Why the study?
Can ultrasoundcardiography reliably record the movement of the mitral ring in intact subjects?

Can ultrasoundcardiography reliably record the movement of the mitral ring in intact subjects?
This early study demonstrates that ultrasoundcardiography can record mitral ring movement, establishing a baseline measurement of 1.6 ± 0.4 cm in normal subjects.

Supports mitral ring assessment by ultrasoundcardiography in normals; leaves open diagnostic utility in heart disease.
An identifiable ultrasound “echo” can be received, it is believed, from the mitral ring. Ring movement may thus be recorded in the intact subject. The recording shows a ventricular dimension type of curve, characteristically different from the well-known mitral valve echo pattern. Recorded from the apical area in 25 normal subjects, the movement amounted to 1·6 ± 0·4 cm, and the curve contour was remarkably constant. Deviations from normal were seen in heart disease.

Zaky et al. (1967) conducted an observational in Normal subjects and heart disease (n=25). Ultrasoundcardiography was evaluated on Mitral ring movement. Ultrasoundcardiography of the mitral ring in 25 normal subjects demonstrated a remarkably constant movement of 1.6 ± 0.4 cm, with deviations from this normal pattern seen in heart disease.
