Young Athlete With Complex Aneurysmal Coronary Stenosis.

Kawasaki disease is an acute vasculitis that occurs predominantly in infants and children younger than 5 years old. If undiagnosed and untreated, the risk of developing coronary artery aneurysms increases to about 20%. In patients who present with angina and are found to have coronary artery aneurysm on imaging and angiography, Kawasaki disease should be considered as one of the leading diagnoses.
