Name of the Procedure:

Transthoracic Echocardiography with Contrast, or without Contrast Followed by with Contrast, Real-Time with Image Documentation (2D), Includes M-Mode Recording, When Performed, During Rest and Cardiovascular Stress Test Using Treadmill, Bicycle Exercise, or Pharmacologically Induced Stress (HCPCS Code: C8928)

Summary

This is a non-invasive heart imaging procedure that uses ultrasound to create real-time images of the heart. It can be done with a contrast agent to improve image clarity. The test includes monitoring heart function during both rest and stress conditions, induced either by exercise (treadmill or bicycle) or medication.

Purpose

The procedure helps diagnose and monitor heart conditions such as coronary artery disease, heart valve issues, and cardiomyopathy. It aims to assess heart function and the blood flow through the heart chambers and valves under various conditions.

Indications

• Chest pain or discomfort, suggesting coronary artery disease
• Shortness of breath, fatigue, or palpitations
• Abnormal heart sounds or murmurs
• Known heart conditions requiring periodic evaluation
• Pre-surgical assessments
• Unexplained fainting (syncope) episodes

Preparation

• Patients may need to fast for a few hours before the procedure.
• Regular medications usually continue unless advised differently by the healthcare provider.
• Inform the healthcare provider of any allergies, especially to contrast agents.
• A baseline electrocardiogram (ECG) may be performed prior to the test.

Procedure Description

1. Initial Assessment: The patient lies on an examination table, and echocardiography gel is applied to the chest.
2. Resting Echo: An ultrasound transducer is moved over the chest to capture images of the heart at rest.
3. Stress Induction:
   • Exercise: The patient uses a treadmill or bicycle to increase heart rate.
   • Pharmacological: If unable to exercise, medication is administered to mimic the effects of exercise.
4. Stress Echo: Additional ultrasound images are captured during and immediately after the stress phase.

If contrast is used, it is usually administered intravenously to improve image quality.

Duration

The entire procedure typically takes about 45 to 60 minutes.

Setting

Performed in a hospital, outpatient clinic, or specialized cardiovascular diagnostic center.

Personnel

• Cardiologist or echo technician performing the ultrasound.
• Nursing staff to assist and monitor the patient.
• Possibly an anesthesiologist or specialized nurse if sedation or pharmacological agents are used.

Risks and Complications

• Common Risks: Mild discomfort from the pressure of the transducer, potential allergic reaction to contrast agents.
• Rare Risks: Arrhythmias during the stress test, adverse reactions to stress-inducing medication (if used), localized pain or bruising at IV site.

Benefits

The procedure provides detailed images to help diagnose heart conditions and assess their severity, improving the accuracy of treatment plans. Results are typically available shortly after the procedure.

Recovery

• Patients can usually resume normal activities right after the procedure.
• It is essential to follow any specific instructions given by the healthcare provider.
• Follow-up appointments may be scheduled to discuss results and further management.

Alternatives

• Exercise Stress Test: Without imaging, monitors heart function and ECG during physical exertion.
• Nuclear Stress Test: Uses a small amount of radioactive material to visualize blood flow to the heart.
• Cardiac MRI or CT: Advanced imaging techniques offering different perspectives of heart structures and function.

Patient Experience

During the procedure, the patient might feel slight discomfort due to the transducer's pressure or the IV infusion of contrast. Post-procedure, there's usually no pain, and any discomfort subsides quickly. Walking or light activity is generally possible immediately after the test, barring any specific contraindications from the healthcare provider.
