An echocardiogram (also called an "echo") is a non-invasive procedure that physicians use to diagnose cardiovascular disease. It uses sound waves to see all four chambers of the heart, the heart valves, the great blood vessels entering and leaving the heart and the sack around the heart. Once doctors diagnose a problem with the heart, they can help determine the right treatment.
Echocardiography allows doctors to visualize the anatomy, structure and function of the heart. It can show the physician if there is a heart valve problem, or how severe the problem is. It can also show if there is an abnormal blood flow within the heart.
