What is involved in having an echocardiogram?
Echocardiogram (Cardiac Ultrasound)
An echocardiogram, also known as a cardiac ultrasound, is a non-invasive test that allows doctors to assess the structure and function of the heart. The test uses high-frequency sound waves to create detailed images of the heart and its surrounding blood vessels, and is similar to the scans used during pregnancy.
What can I expect:
During an echocardiogram, you will be asked to lie down on a table while the sonographer applies a special gel to your chest and presses (often quite firmly) with an echo probe (see below). This gel helps the sound waves travel more easily and produces clearer images of the heart. You will usually be required to remove clothing from the upper part of the body for this test. Hospital gowns and sheets are available to maintain modesty.
The sonographer places a small device called a transducer, or echo probe, on your chest. The transducer sends out sound waves and picks up the echoes that bounce back from the heart. These echoes are then converted into images that can be seen on a screen.
The sonographer may ask you to change positions or hold your breath during the test to obtain different views of the heart. The test usually takes about 30 - 45 minutes to complete.
Why it's Done:
An echocardiogram can help diagnose or evaluate a variety of heart conditions, including:
Heart valve disease, such as leaky or narrowed valves
An enlarged heart (dilated cardiomyopathy)
Heart failure
Congenital heart defects
Increased wall thickness (from hypertensive heart disease or hypertrophic cardiomyopathy)
Problems with the systolic function (pumping) or diastolic function (relaxing) of the heart's muscle
Evaluate a dilated aortic root or ascending aorta
Risks:
Echocardiograms are considered very safe and do not involve any radiation exposure. The test is non-invasive and does not require any incisions or injections. The gel applied to your chest may feel cold or sticky, but it is not harmful. The sonographer may need to press firmly, which can be uncomfortable.
After the Test:
Once the echocardiogram is complete, you will be able to resume your normal activities straight away. The results of the scan are often available soon after the test and your cardiologist will review the images and discuss the results with you. This may be on the day of the scan or at a follow-up appointment. In some cases, you may receive a letter detailing the results and follow up. Additional testing or treatment may be recommended based on the results of the test.
Conclusions:
An echocardiogram is a valuable and safe diagnostic tool that can help doctors assess the structure and function of the heart muscle, valves and nearby structures. The test is non-invasive and relatively quick, making it a convenient option for many patients.
