Echo (ultrasound) Lab

The information obtained from these monitoring tests help your doctor make an accurate diagnosis and develop a treatment plan that is right for you. All tests are available on an outpatient basis.

An echocardiogram (echo) is a test that uses ultrasound waves to examine the heart. During the test, a small microphone-like device called a transducer is held against the chest, producing images of the heart that are displayed on a screen. An echo test may be used to measure the size of the heart and heart muscle, determine pumping strength, discover valve problems and to detect blood clots and fluid around the heart.

There are several types of echocardiograms:

This test combines an ultrasound study of the heart with an exercise test, enabling the doctor to learn how a patient’s heart functions when it is made to work harder. In this 3-part test, a resting echocardiogram is done, followed by a treadmill or stationery bike exercise session, and then another echo is done while the heart is still beating rapidly. Because exercise echo testing is effective in discovering blockages of the coronary arteries, it is especially useful in the diagnosis of coronary heart disease.

This type of testing diagnoses coronary heart disease by combining an ultrasound study of the heart with a drug-induced stress test. Used for patients, who are unable to exercise on a treadmill or stationary bicycle, the test is given after injection of a drug called dobutamine that produces an effect on the heart similar to exercise. An echocardiogram is first done while the heart is "resting." Dobutamine is then infused into a vein in the arm, causing the heart to pump faster and harder. Additional echo images are then obtained during and after the dobutamine infusion. This testing reveals which areas of the heart muscle are blocked or narrowed and do not receive an adequate blood supply.

This type of echo test examines the heart by using ultrasound waves that emit from inside the esophagus. Because the esophagus is located just behind the heart, the images provided are often much clearer than are possible with a standard echocardiogram. After administering an anesthetic to the throat and a low dose sedative by IV, a long flexible tube is inserted into the mouth and down the esophagus. A small transducer at the tip of the probe emits ultrasound waves that convert into moving images of the heart. A transesophageal echo is generally performed when doctors want to examine hard-to-see structures of the heart and to detect masses, valve infections and defects tears in the aorta or to examine prosthetic heart valves. In cases of obesity or chronic lung disease, this type of testing enables a clear view of the flow of blood through the heart chambers and valves that is not possible using other types of ultrasound testing.
