Zusammenfassung:Background:To clarify ventricular function in patients with asymptomatic coronary artery occlusion (ACAO) after Kawasaki disease (KD).Methods and Results:We enrolled 65 patients with coronary artery lesions who had undergone cardiac magnetic resonance (CMR). Median age at CMR was 29 years. CMR was performed to evaluate only the transmural extent of late gadolinium enhancement (LGE) and ejection fraction (EF). Based on the depth of LGE, it was classified into 5 groups: 0% (G0), 1–25% (G1), 26–50% (G2), 51–75% (G3), and 76–100% (G4). We investigated the relationship of the degree of LGE and EF. Further, we also evaluated the EF among 3 groups [ACAO, myocardial infarction (MI), and noncoronary artery occlusion (Non-CO)]. The grade of LGE and the LVEF (mean±SD, %) were as follows: G0 (n=24, 52.6±4.8), G1 (n=13, 50.8±4.4), G2 (n=15, 49.1±5.6), G3 (n=9, 30.9±9.1), and G4 (n=9, 27.7±6.8). LVEF in patients with G3 and G4 was significantly low (P
