Two-dimensional echocardiographic techniques accurately measure segmental wall movement and in some instances are more accurate than cineangiography.
Ultrasonic investigations of the heart were originally based on the M-mode display which has been extremely useful in the study of ventricular size and function, and heart valve function. However, the advent of two-dimensional real-time scanners has superseded M-mode, particularly in the field of structure recognition, and in the evaluation of left ventricular performance in patients with segmental myocardial disease. Kisslo et (1977) have shown that two-dimensional echocardiographic techniques are able to measure segmental wall movement very accurately, and in some instances are more accurate than cineangiography.
A Sun, study conducted a review in Segmental myocardial disease. Two-dimensional echocardiography vs. M-mode echocardiography and cineangiography was evaluated on Accuracy of segmental wall movement measurement. Two-dimensional echocardiographic techniques accurately measure segmental wall movement and in some instances are more accurate than cineangiography.
