Echocardiography

Echocardiography or echo, is a painless test that uses sound waves to create moving pictures of your heart. The pictures show the size and shape of your heart. They also show how well your heart's chambers and valves are working.

Echo also can pinpoint areas of heart muscle that aren't contracting well because of poor blood flow or injury from a previous heart attack. A type of echo called Doppler ultrasound shows how well blood flows through your heart's chambers and valves.

Echo can detect possible blood clots inside the heart, fluid buildup in the pericardium (the sac around the heart), and problems with the aorta. The aorta is the main artery that carries oxygen-rich blood from your heart to your body.

Types of Echocardiography

Transesophageal Echocardiography

Your doctor may have a hard time seeing the aorta and other parts of your heart using a standard transthoracic echo. Thus, he or she may recommend transesophageal (tranz-ih-sof-uh-JEE-ul) echo, or TEE.

During this test, the transducer is attached to the end of a flexible tube. The tube is guided down your throat and into your esophagus (the passage leading from your mouth to your stomach). This allows your doctor to get more detailed pictures of your heart.

Stress Echocardiography

Stress echo is done as part of a stress test. During a stress test, you exercise or take medicine (given by your doctor) to make your heart work hard and beat fast. A technician will use echo to create pictures of your heart before you exercise and as soon as you finish.
