| Outline of Final Research Achievements |
Echocardiographic evaluation is essential in daily clinical practice for children with heart diseases. In this study, we aimed to establish normative values and clinical decision criteria of the following echocardiographic indices in children.
(1) We showed that dissipative energy loss within the left ventricle was associated with left ventricular diastolic dysfunction. (2) We obtained normative values for a mitral valve coaptation depth, and showed that the effectiveness of the mitral valve plasty for functional mitral valve regurgitation in children with dilated cardiomyopathy could be predicted by the coaptation depth. (3) We established the diagnostic criteria of Doppler-derived hemodynamic parameters for prosthetic mitral valve obstruction in children. (4) We demonstrated that the indices of right ventricular longitudinal function did not properly reflect right ventricular systolic function in children with repaired Tetralogy of Fallot.
