Angiographic abnormalities of the morphologically left ventricle in the presence of Ebstein's malformation.

Cineangiography of the morphologically left ventricle was performed in 10 patients with Ebstein's malformation. The angiographic findings included left ventricular contour abnormalities (8), mitral valve prolapse (7) and global hypokinesia (5). Left ventricular abnormalities were present whether the left ventricle was normally placed or in mirror-image position in congenitally corrected transposition. Abnormalities of the morphologically left ventricle in Ebstein's malformation have received little attention in the past. Frequent occurrence of these abnormalities should make careful evaluation of the morphologically left ventricle mandatory in all patients with Ebstein's malformation.
