Right oblique subxiphoid view for two-dimensional echocardiographic visualization of the right ventricle in congenital heart disease.

Two-dimensional echocardiography in the right oblique subxiphoid view (ROSV) was used to visualize all right ventricular components in 351 patients younger than 2 years of age (100 normal and 251 with various types of congenital heart disease). The ROSV, which is anterior and parallel to the ventricular septum, displays all right-sided cardiac components, the left atrium and the aorta. This view provided the correct diagnosis in patients with pulmonary stenosis or atresia with intact ventricular septum, Ebstein's anomaly, tricuspid atresia, infundibular ventricular septal defect, tetralogy of Fallot and truncus arteriosus. In all patients studied with the ROSV, an excellent definition of morphologic characteristics, equivalent to that in the right oblique axial angiocardiographic view, was achieved. The ROSV should be used routinely to delineate the right ventricular anatomy in all infants with congenital heart disease.
