title: Analysis of the correlation between the ostium surface area and divergence angles of coronary arteries and type of coronary circulation, heart dimensions and sex.
abstract: BACKGROUND
  The objective of this study was to analyse the correlation between the diameter and divergence angles of coronary arteries and type of coronary circulation, heart.
  
  
  METHODS
  The study was carried out on 102 human hearts (59 male and 43 female). The coronary arteries and veins and the ascending aorta were filled with Polimal epoxide resin. Soft tissues were dissolved with hydrochloric acid after solidification of the resin. The specimens were measured for divergence angles of the coronary arteries. Correlations between vessel divergence angle, coronary circulation type, and heart size were analysed in the casts.
  
  
  RESULTS
  Data analysis indicated a greater diameter of the left coronary artery in both sexes, and in the co-dominant and left-dominant coronary circulation type.
  
  
  CONCLUSIONS
  No correlations between divergence angles of coronary vessels and gender or coronary circulation type were found.
