Which imaging study is most appropriate to evaluate structural heart disease in a patient with a heard murmur?

• A. Echocardiogram
• B. Chest X-ray
• C. CT scan
• D. MRI

Answer: (A)

When a murmur suggests possible structural heart disease, you need a test that can directly visualize the heart valves and chambers and show how blood is actually moving through them. An echocardiogram fits this best because it uses ultrasound to image valve anatomy, chamber sizes, and wall motion in real time, and it includes Doppler assessment to measure blood flow, gradients, and regurgitation or stenosis. This lets you quantify severity, assess function, and identify defects like valve disease or septal defects, all noninvasively and at the bedside if needed. Chest X-ray can hint at problems by showing heart size or edema but doesn’t reveal valve structure or function. CT provides detailed anatomy and is great for coronary vessels, but involves radiation and doesn’t evaluate valve hemodynamics well. MRI offers excellent tissue and functional information, yet it is less accessible, longer, and not as practical for initial murmur evaluation. Therefore, echocardiography is the most appropriate first-line study to evaluate structural heart disease in a patient with a heart murmur. If image quality is limited, transesophageal echo may be used for better visualization.
