Multimodality Cardiac Imaging in a Patient with Kawasaki Disease and Giant Aneurysms

Area of Science:

• Pediatric Cardiology
• Rheumatology
• Medical Imaging

Background:

• Kawasaki disease is a leading cause of acquired heart disease in children.
• Intravenous immunoglobulin (IVIG) has reduced morbidity, but serious complications persist.
• Coronary artery aneurysms and calcification remain significant long-term risks.

Purpose of the Study:

• To highlight a case of progressive giant coronary artery aneurysms in an adolescent with a history of Kawasaki disease.
• To emphasize the importance of multimodality imaging in the long-term management of Kawasaki disease.
• To review current literature on managing Kawasaki disease complications.

Main Methods:

• Case report of an adolescent patient with a history of infant Kawasaki disease.
• Review of medical literature on Kawasaki disease and its cardiac sequelae.
• Discussion of multimodality imaging techniques (e.g., echocardiography, CT, MRI) in diagnosis and management.

Main Results:

• The patient developed giant coronary artery aneurysms and calcification despite initial IVIG treatment.
• Multimodality imaging was essential in characterizing the extent and progression of coronary artery abnormalities.
• Literature review confirms the potential for severe, progressive cardiac damage in Kawasaki disease.

Conclusions:

• Kawasaki disease requires vigilant long-term cardiac monitoring due to the risk of progressive aneurysms.
• Multimodality imaging plays an integral role in the comprehensive management of Kawasaki disease complications.
• Early and ongoing imaging surveillance is critical for preventing adverse cardiovascular events.
