[Anatomical corrected malposition. Report of two new cases (author's transl)].

Two new cases of anatomically corrected malposition of great arteries (A-V concordance or discordance; V-GA concordance; subaortic conus) are reported. One of these has been studied from the autoptic specimen and is in situs solitus with A-V concordance (SDL), which is the most common form of such alteration. The second case, studied by angiography, is in situs inversus with A-V concordance (ILD). This form has been described only once in the literature, but some Authors still consider it "possible" such an anormally rather than reported as yet. Finally the anomalies most frequently associated to the MACGA and the possible morphogenesis are valuated.
