2D Echo, or two-dimensional echocardiography, is a non-invasive diagnostic test that uses sound waves to produce real-time images of the heart. It allows doctors to view the structure and movement of the heart's chambers, valves, and surrounding blood vessels.

This test is commonly used to evaluate heart function, detect congenital heart defects, assess damage after a heart attack, and monitor heart valve diseases. 2D Echo is safe, painless, and does not involve any radiation, making it an essential tool in routine cardiac care.
