An echocardiogram is an imaging procedure that uses ultrasound to visualize the heart. With this procedure, doctors can see the heart in a two-dimensional or three-dimensional view to assess structure, blood flow, valve abnormalities, defects, and cardiac output.
There are two types of echocardiography:
You may need an echocardiogram if you have:
Transthoracic echocardiogram (TTE) is the standard echocardiogram frequently used to get a generic picture of the heart. To do this procedure, a probe called an echocardiographic transducer is placed on the chest wall from the outside. Images are taken by moving the probe around to see different angles of the heart on a video monitor.
The TTE is completely noninvasive. A physician can quickly get an idea of the structure, valves, and flow through the heart.
A transesophageal echocardiogram (TEE) is used to take clearer pictures of the heart in cases where there are questions with the transthoracic echocardiogram. In this procedure, the probe is placed into the esophagus while the patient is sedated. This method allows the probe to be closer to the heart without any other structures (ribs, lungs, or muscle) to interfere with the ultrasound. The aorta, valves, and pulmonary artery are better visualized with a TEE.
