The purpose of this clinical research study is to determine how well CARDIOLITE® rest and stress myocardial (heart) imaging can define the pediatric Kawasaki disease (KD) population into high and low risk categories of developing cardiac (heart) events (complications) from 1 year through 3 years after image completion. The safety of CARDIOLITE® rest and stress heart imaging will also be studied.
Determine the predictive value of CARDIOLITE® rest and stress myocardial perfusion imaging (MPI) to define a pediatric population with Kawasaki Disease (KD) at high and low risk of developing cardiac events.
