Contrast Echocardiogram

What is a Contrast Echocardiogram?

An echocardiogram is an exam performed using a probe that emits ultrasounds to obtain images of the heart. Typically, the echocardiogram is performed while at rest.

In a Contrast Echocardiogram, an ultrasound-enhancing agent (contrast) is used to improve the quality of the images.

What is the purpose of this examination? What are the indications?

When your doctor determines that an echocardiogram is necessary but the image quality is not sufficient, a contrast agent can be used. This contrast is different from those used in CT or MRI scans.

This test allows for better visualization of the endocardium (the inner part of the heart), the Doppler contour (valve function), and the detection of intracardiac masses, abnormal openings, and/or intracardiac shunts.

Are there risks?

This is a safe test—ultrasounds are harmless to health, and the risk of allergic reactions is extremely low (<1/10,000).

How is a Contrast Echocardiogram performed?

• The Contrast Echocardiogram is conducted by a team of experienced professionals, including a cardiologist, a nurse, and a cardiopulmonary technician.
• The test is performed with the patient lying down.
• An intravenous catheter is placed for the administration of the contrast agent.
• Electrodes are applied to the chest for heart rhythm monitoring, and blood pressure is measured.
• The room lighting is dimmed to allow for optimal visualization of the images on the ultrasound monitor.
• A transparent gel is applied to the left side of the chest, where the probe or transducer is positioned. This transducer emits and receives ultrasound beams reflected by various structures, converting them into images on the monitor.
• Images are taken before, during, and after the administration of the contrast agent.
• The procedure takes approximately 30–45 minutes.
• Preliminary results are provided immediately after the test.
• After the procedure, you can resume your normal daily routine.

How should you prepare for the test?

• No special preparation is required.
• You may take your usual medications and do not need to fast.
• Inform the team if you have any known allergies.

On the Day of the Test:

• Bring previous and recent test results (e.g., Echocardiogram, Electrocardiogram (ECG), Stress Test, Catheterization, Coronary CT Angiography, Surgical Reports if applicable), and other reports or lab results.
• Bring all your medications.
• Arrive 30 minutes before the scheduled time.
