Abstract:
Purpose To explore three-dimensional speckle tracking imaging (3D-STI) in assessing changes of left ventricular global systolic function of viral myocarditis (VMC) child patients before and after treatment.Materials and Methods Thirty-eight VMC child patients were given related treatment and blood biochemistry test,routine ECG and 3D-STI were taken for examination before and after surgery when the index became normal and results were recorded.Left ventricular end-diastolic diameter (LVEDd),left ventricular endsystolic diameter (LVEDs),left ventricular end-diastolic volume (LVEDV),left ventricular end-systolic volume (LVESV),left ventricular ejection fraction (LVEF),global longitudinal strain (GLS),global radial strain (GRS),global circumferential strain (GCS) and global area strain (GAS) were obtained.Results Postoperative cardiac troponin I and N-terminal pro-B-type natriuretic peptide levels were all statistically lower than those before surgery (P＜0.05).Difference of preoperative and postoperative LVEDd,LVEDs,LVEDV,LVESV and LVEF was of no statistical significance (P＞0.05).Postoperative GLS,GRS,GCS and GAS were statistically higher than those before surgery (P＜0.05).Conclusion 3D-STI can evaluate abnormal change of left ventricular myocardial function of VMC child patients.
