Abstract
In a diagnosis of neonatal congenital heart disease, transthoracic echocardiography is the method of first choice. We can perform the repeated transthoracic echocardiography noninvasively. " Serial axial view scan " is a neonatal echocardiographic method to scan axial images from subcostal abdomen to suprasternal notch continually like computed tomography. Using this method, it is easy to obtain a segmental diagnosis of the congenital heart disease and is superior in the reproducibility of the diagnosis from saved images. The probe operation is relatively easy, but knowledge and a lot of experience with congenital heart disease are necessary for a diagnosis.
By the repeated neonatal echocardiography in the neonate with congenital heart disease, we can also observe the change of circulatory dynamics from fetal circulation to neonatal circulation over time. Within the cardiac ability of the neonate with congenital heart disease, we manage the balance between systemic and pulmonary circulation, and devise to preserve the systemic circulation for survival without critical hypoxemia.
