title: [Anatomic study of the coronary arteries in transposition of great vessels].
abstract: The authors studied 64 hearts presenting transposition of the great arteries, in order to evaluate the pattern of distribution and origin of the main coronary arteries. Regarding the origin in each sinus of Valsalva, there was no significant difference with the data from the literature. It was also evaluated the precise site of origin inside the sinuses, which were divided in three thirds: the medial and those adjacent to the valvar commissures. We observed that, although the coronary ostia took origin from the medial third in more than half of the cases, there was some variation when considering the different patterns of distribution. This observations is relevant, since, when Jatene's procedure is considered, the surgical disinsertion of a coronary artery may put at risk the valvar leaflet, when the ostium is near the commissure.
