Abstract
Since evaluation of the right ventricular (RV) outflow tract is of great importance for diagnosis, prognosis, and surgical management of congenital heart disease, we examined the value of two-dimensional echocardiography to assess the RV outflow tract by using a new approach—the subcostal elongated right oblique view (SEROV). We studied 30 normal children and 54 children with congenital heart disease (ages 1 day to 3 years). Significant pulmonary infundibular obstruction was present in 22 patients with conotruncal malformations. To obtain the SEROV from the subcostal short-axis view at the aortic valve level [1, 2], the transducer was slightly rotated clockwise. The anterior angulation was about 30°, so that the ascending aorta was seen in its long axis, providing a picture similar to that obtained by a right ventriculogram in the elongated right anterior oblique view [3].
