Abstract

The arteries that irrigate the lung face of the heart and the posterior surface of the right ventricle present a variable expression. 154 fresh hearts were evaluated obtained as autopsy material. The coronary arteries were subjected to injection process with synthetic resins. Right posterolateral branch (right dominance) was observed in 24 hearts (15.6%), of which 20 (83.3%) originated of the right coronary artery and 4 of the marginal right artery. Within these in 40% of the cases were observed in short posterior interventricular branch and 5.6% with long branch (p = 0.001). It was observed diagonal branches in 74 hearts (48%), anterosuperior branches in 126 (81.8%) and lateral branches in 123 (79.9%). The branches of middle longitude were the most frequent: diagonals (52.3%); anterosuperiors (62.7%) and laterals (47.1%). The calliper of the diagonal branches was of 2.01 mm (SD 0.59). Of the diagonal branches, those that presented smaller calliper corresponded to the specimens with left dominance (1.88 mm SD 0.52), without significance (P 0.608), while the lateral branches of more calliper corresponded to hearts with left dominance (p=0.022). It was also observed myocardial bridges in 11 diagonal branches (14.9%); in 6 anterosuperior branches (4.8%) and in 2 right posterolateral branches (8.3%). The lateral branches do not presented myocardial bridges. Prevalence of the right posterolateral branch was observed in a sixth of the individuals with right dominance, and the majority of diagonal branches presented an epicardic course that concluded in the middle third of the obtuse face of the heart.
