OVERVIEW
An echocardiogram is an ultrasound test that checks the structure and function of your heart. An echo can diagnose a range of conditions including cardiomyopathy and valve disease. There are several types of echo tests, including transthoracic and transesophageal. Talk with your provider about the type that’s best for you.
What is an Echocardiogram?
An echocardiogram (echo) is a graphic outline of your heart’s movement. During an echo test, your healthcare provider uses ultrasound (high-frequency sound waves) from a hand-held wand placed on your chest to take pictures of your heart’s valves and chambers. This helps the provider evaluate the pumping action of your heart.
Providers often combine echo with Doppler ultrasound and color Doppler techniques to evaluate blood flow across your heart’s valves.
Echocardiography uses no radiation. This makes an echo different from other tests like X-rays and CT scans that use small amounts of radiation.
Who performs an echo test?
A technician called a cardiac sonographer performs your echo. They’re trained in performing echo tests and using the most current technology. They’re prepared to work in a variety of settings including hospital rooms and catheterization labs.

Procedure Steps
- Preparation: No special preparation is usually needed for TTE. For TEE, patients may need to fast for several hours.
- Conducting the Exam:
- TTE: Patients lie on their left side, and a gel is applied to the chest. The transducer is moved around to capture images of the heart.
- TEE: A sedative may be given, and the probe is gently inserted into the esophagus to capture images.
- Image Acquisition: The echocardiogram is performed by a trained technician or cardiologist who captures various views of the heart.
- Post-Procedure Care: Most patients can resume normal activities immediately after TTE. For TEE, monitoring is done until the sedative wears off.
