Right Ventricular Outflow Tract Assessment by a New Two-Dimensional Echocardiographic Approach: The Subcostal Elongated Right Oblique View
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 .
