An echocardiogram (echo) is a test that uses high frequency sound waves (ultrasound) to make pictures of your heart. The test is also called echocardiography or diagnostic cardiac ultrasound.
- The size and shape of your heart, and the size, thickness and movement of your heart’s walls.
- How your heart moves.
- The heart’s pumping strength.
- If the heart valves are working correctly.
- If blood is leaking backwards through your heart valves (regurgitation).
- If the heart valves are too narrow (stenosis).
- If there is a tumor or infectious growth around your heart valves.
The test also will help your doctor find out if there are:
- Problems with the outer lining of your heart (the pericardium).
- Problems with the large blood vessels that enter and leave the heart.
- Blood clots in the chambers of your heart.
- Abnormal holes between the chambers of the heart.
