Contrast Echocardiogram

What is a Contrast Echocardiogram?

Contrast Echocardiogram can use an ultrasound enhancing agent (contrast) to improve the quality of the images or agitated saline.

It allows you to better visualize the endocardium (inner part of the heart) and the doppler contour (valve function), detect intracardiac masses, anomalous orifices and/or intracardiac shunts.

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 to the contrast is extremely low (<1/10,000).

How is a Contrast Echocardiogram performed?

• The Contrast Echocardiogram is performed 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 exam?

• 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 exam:

• Bring previous and recent cardiac exams (e.g. Echocardiogram, Electrocardiogram (ECG), Treadmill Stress test, Cardiac CT, Coronary angiography, Surgical report - if you have had surgery), other reports and blood tests.
• Bring all medication.
• Arrive 30 minutes before the scheduled time.
• Go to Floor Zero - Outpatient Consultations - Special Exams unit.
