Imaging the delayed complications of childhood Kawasaki disease

Area of Science:

• Cardiology
• Pediatric Medicine
• Radiology

Background:

• Kawasaki disease (KD) is a leading cause of acquired pediatric heart disease.
• Long-term complications, particularly coronary artery aneurysms, require lifelong monitoring.
• Understanding surveillance strategies is crucial for managing KD sequelae into adulthood.

Purpose of the Study:

• To review the long-term complications of Kawasaki disease.
• To focus on imaging surveillance of coronary arteries in adolescence and adulthood.
• To evaluate the advantages and disadvantages of various imaging modalities.

Main Methods:

• Literature review of studies on Kawasaki disease complications and cardiac imaging.
• Analysis of imaging techniques including echocardiography, MRI, and CT angiography.
• Discussion of practical examples illustrating imaging findings and surveillance protocols.

Main Results:

• Coronary artery abnormalities are the most significant long-term complication of Kawasaki disease.
• Echocardiography is the primary screening tool, but limitations exist for detecting subtle changes or in obese patients.
• Advanced imaging like MRI and CT angiography offer detailed anatomical information but have different risk-benefit profiles.

Conclusions:

• A multimodality imaging strategy is often required for comprehensive surveillance of coronary arteries in patients with a history of Kawasaki disease.
• Tailoring surveillance protocols based on initial findings and patient age is essential.
• Early detection and monitoring of coronary artery complications can guide timely intervention and improve long-term outcomes.
