Prognostic value of stress perfusion cardiac magnetic resonance imaging in Kawasaki disease with coronary artery aneurysms: A 10-year retrospective cohort study

In KD patients with CAA, inducible perfusion defects on spCMR were associated with increased MCE risk, whereas a normal spCMR in AHA risk levels 3-4 was reassuring. Serial spCMR identified evolving ischemia, guided revascularization decisions, and informed post-intervention management. These findings support the incorporating spCMR into longitudinal surveillance pathway for high-risk KD patients.
