An essential test in the evaluation of a 2-year-old being managed for Kawasaki disease is:

• A. Echocardiogram
• B. Electrolytes
• C. Cholesterol
• D. Streptococcal antibody titer

Answer: (A)

Kawasaki disease carries the risk of developing coronary artery involvement, including aneurysms, which has the biggest impact on prognosis and treatment decisions. An echocardiogram directly visualizes the heart and, most importantly, the coronary arteries to detect dilation or aneurysm, as well as assess ventricular function and valvular integrity. This information guides how aggressively to treat and how to monitor the child, including decisions about IVIG use and any antiplatelet or anticoagulant therapy. In a 2-year-old with suspected or treated Kawasaki disease, baseline echocardiography is essential to establish cardiac status and is repeated to track changes over time. Electrolytes, cholesterol, and streptococcal antibody titers don’t reveal coronary artery involvement or cardiac risk in Kawasaki disease and thus don’t provide the critical information needed to guide management in this context.
