title: [Partial distortion of the great vessels in dextroposition and intrapulmonary continuity (Taussig-Bing variety)].
abstract: A case of partial distortion of the great arteries in a patient with dextroposition and mitropulmonary continuity is described (Taussig-Bing variety). The embryogenesis and anatomy in comparison with others similar cases found in the literature is analyzed and discussed. The cardiac defect is a partial distortion of the great arteries and its analysis permit to conclude that the conal muscle is not an important anatomic feature; its presence does not play a important roll in the genesis of the heart malformation. This case is compared with the so called "transposition of the great arteries with posterior aorta" and it is concluded that these heart defects have the same embryogenesis and that the relation of the great arteries themselves and with the ventricles depend of different grades of incorporation of the conus. It can be said also that this group of cardiac defects are not true transpositions of the great vessels, because the aorta does not arise anteriorly to the crista supraventricularis.
