Özet
Aim: To investigate myocardial deformation and function during treatment for Kawasaki disease (KD) in children. Methods: We performed speckle tracking echocardiography (STE) and tissue Doppler imaging (TDI) in 15 children with KD and 15 healthy children during treatment for KD. STE was performed for longitudinal and circumferential strain (S) and strain rate (SR) at the left ventricle (LV) and for longitudinal S and SR at the right ventricle (RV). TDI was performed at the base of interventricular septum (IVS), LV, and RV. Results: Among TDI parameters, Em and ejection time (ET) at IVS, ET at LV and ET at RV obtained obtained before treatment were significantly lower in patients with KD compared to controls. After treatment, in spite of improvements, ET at IVS and ET at RV remained significantly lower in patients with KD compared to controls. Left ventricular global longitudinal and circumferential S and SR values obtained before treatment were significantly lower in patients with KD compared to controls. Left ventricular S and SR values were found to be increased after treatment. However, left ventricular global circumferential S value remained significantly lower in patients with KD compared to controls. There were no significant differences in right ventricular global longitudinal S and SR values between patients and controls before treatment. Conclusion: During acute phase, patients with KD have reduced global left ventricular S and SR which may be more sensitive indicators of myocardial inflammation. This study showed gradual improvements in left ventricular myocardial function during treatment for KD.
