OBJECTIVES: The aim was to evaluate the role of tissue Doppler imaging (TDI) and speckle tracking echocardiography (STE), to identify myocardial dysfunction, and to evaluate myocardial segmental deformation in acute viral myocarditis. METHODS: Twenty-one patients and twelve healthy children were studied prospectively. The TDI and STE were performed before and after treatment. The myocardial velocities (Sm , Em , and Am ) and time intervals (isovolumic contraction, isovolumic relaxation, and ejection times [ET]) at interventricular septum (IVS), left, and right ventricular basal segments were examined by TDI. The left ventricular global longitudinal strain (LVGLS) and strain rate (LVGLSR), left ventricular global circumferential strain (LVGCS) and strain rate (LVGCSR), and right ventricular global longitudinal strain (RVGLS) and strain rate (RVGLSR) were examined by STE. RESULTS: Sm and Em at IVS and at LV, ET at IVS, ET at RV, ET at LV were significantly lower in patients before treatment than controls. LVGLS, LVGLSR, LVGCS, LVGCSR, RVGLS, RVGLSR were significantly decreased in patients before treatment than controls. There was significant improvement for LVGLS, LVGLSR, LVGCS, LVGCSR, and RVGLS in patients after treatment. Sm , Em , and Am at LV were significantly lower in patients before treatment than in patients after treatment. In spite of improvements, Sm , Em , and ET at IVS, LVGLS, LVGLSR, LVGCS, LVGCSR were significantly lower in patients after treatment than controls. CONCLUSIONS: The TDI and STE were useful methods for detection of early myocardial dysfunction and evaluation of treatment outcomes in acute viral myocarditis.
