The arteriographic demonstration of a linear, striated arterial pattern in the anatomic course of the draining vein is reliable evidence of venous extension by a tumor and represents the supply to the intravenous component of the neoplasm. In additio

The plain roentgenographic and angiocardiographic features of 15 patients with Ebstein's anomaly of the tricuspid valve were reviewed. Of note on the plain roentgenogram was the fact that the "posterior bulge" seen on the lateral view was demonstrate

MR was used to differentiate the classical form of tricuspid atresia, in which the atrioventricular connection is absent, from a rare type of right atrioventricular obstruction, in which the valve is imperforate, and from some Ebstein's malformations

The diagnosis of origin of both great arteries from the morphologic right ventricle requires angiocardiographic demonstration that (1) the pulmonary artery and aorta arise from the same ventricle and the anatomic features of the ventricle are those o
