| Abstract | SUMMARY The levo-transposed aorta has previously been considered diagnostic of corrected transposition of the great arteries and hence ventricular inversion in situs solitus. Increasing experience with conotruncal abnormalities has shown that an abnormally leftward aorta may be found in patients with normally related ven-tricles (D-ventricular loop) and hemodynamically complete transposition of the great arteries; anatomically corrected L-malposition of the great arteries; and rarely in patients with D-ventricular loop, double outlet right and left ventricles. Thus the levo-positioned aorta should suggest a wider spectrum of cardiovascular abnormalities than previously thought. The specific angiocardiographic features of levo-transposition, anatomically corrected malpositions, and D-ventricular loop with levo-transposed aorta are presented in detail; and their differential diagnosis from the very uncommon D-loop, double outlet right and left ven-tricles with an L-malposed aorta is considered. The role of selective biplane angiocardiography in the assessment of these conotruncal abnormalities is stressed. Anatomically corrected malpositions Double outlet right ventricle Corrected transposition Malposition Double outlet left ventricle Transposition THE LEVO-TRANSPOSED AORTA has previously been considered diagnostic of corrected (levo-transposition, L-TGA) transposition of the great arteries .' ` However, increasing experience with conotruncal abnormalities has shown that an abnormally leftward aorta may be found in patients with normally related ventricles (D-ventricular loop) and hemodynamically complete transposition of the great arteries.4'5 Similarly, the angiographic and anatomic features of the levo-transposed (malposed) aorta in anatomically corrected malpositions have been presented elsewhere.6' 7 The uncommon finding of a double outlet right ventricle, D-ventricular loop, L-transposed aorta, bilateral conus, and pulmonic stenosis has also been documented.8 This patient subsequently underwent surgical repair. And finally, we have been able to find one patient recorded in the literature with a D-ventricular loop, double outlet left ventricle, probable valvular and subvalvular pulmonic stenosis, and L-malposition of the aorta.9 Obviously then, the levo-transposed or malposed aorta embraces a wider range of cardiovascular abnormalities than previously thought. Because of increasing surgical expertise in dealing with uncommon conotruncal malformations, and the obvious relevance of precise anatomic diagnosis, we wish to present the differential angiocardiographic diagnosis of the levo-transposed and malposed aorta and to comment on the associated cardiovascular lesions.
