Can heart ultrasound show heart damage?

A cardiac echo: Or u/s is a dynamic study of heart function: wall motion, chamber filling and emptying, and valve motions. It can show damaged wall. It does nothing to detect coronary vessels. It also can find pericardial fluid.

Only gross damage: A cardiac ultrasound (echocardiogram) will show the size and function of the heart chambers and valves as well as the great vessels entering and exiting the heart. While the echocardiogram will detect wall motion abnormalities it will not detect small areas of damage or plaque build up in the coronary arteries (heart disease).
