Speckle tracking as an emerging technique in echocardiography, by virtue of no angle dependence, its beam direction and the direction of the wall movement between the angle of the angle, evaluating the myocardial exercise more accurately and comprehensively, which has been widely used in heart function evaluation for clinical diagnosis and prognosis, providing more accurate information and reflecting higher application value. As study showed, the incidence of congenital heart disease is high, early diagnosis and treatment of cardiac function evaluation and prognosis is essential. This paper through summarizing of speckle tracking technique in tetralogy of Fallot, fetal aortic coarctation, PDA and atrial septal defect Diagnosis of heart disease, that speckle tracking technology has higher clinical value for the diagnosis of congenital heart disease and its evaluation of heart function.
