A distinctive angiographic appearance is described in two patients who had
uncorrected levo-transposition of the great vessels. Although levo-
transposition with inversion of the ventricles usually results in
physiologically corrected transposition, in these patients the anatomy was
arranged in such a way as to result in an uncorrected transposition. The
following elements were responsible for this physiological condition:
normal atrial situs, inverted ventricles with "criss-cross"
atrioventricular flow, levo-transposed great arteries. In addition, the
morphological right ventricle was hypoplastic, left sided and superior to
the left ventricle and the ventricular septum was horizontal in position.
The two ventricles were connected via a large ventricular septal defect.
The importance of accurate, detailed, preoperative angiographic
demonstration of the anatomic situation is stressed.
