Resumen
HERNANDEZ CUAN, Cristina et al. Anatomic variants of coronary circulation. AMC [online]. 2002, vol.6, suppl.1, pp.784-791. ISSN 1025-0255.
Bibliographical sources were reviewed so as to carry out a work about coronary circulation and its variants of the anatomic worm, in which possible common origins of the right coronary artery (RCA) and left coronary artery (LCA) are stressed, resulting in only one coronary artery, the presence of three coronary arteries with different origins and the two mentioned above separately. Different trajectories in the passing over of each of them are shown and the existence of three variants of the norm for RCA and six for short LCA was reflected as to arteries that emit each of them: for RCA, a short RCA which ends in the right edge of the heart a long RCA that ends in the posterior face of the left atrium and the interventricular posterior perforating artery that does not emit terminal branches are known. While the LCA has other variants as the LCA trifurcated; anterior perforating interventricular artery short circunflex; that ends in the obtuse angle of the heart; posterior interventricular as a branch of the circunflex and interventricular double or multiple as branches of the circunflex or of RCA locating paralely one to each others.
