title: [Morphometric study of the left coronary artery].
abstract: BACKGROUND
  The majority of morphometric studies of the left coronary artery is based on one or a few dimensions. The present study was undertaken to measure the dimensions of the left coronary artery, as well as to determine correlations of diameter, length, and divergence angles with heart size and gender.
  
  
  METHODS
  The study was carried out on 102 human hearts (59 male and 43 female). True casts of coronary vessels were obtained using epoxide resins. Specimens were measured for left coronary artery dimensions and heart dimensions.
  
  
  RESULTS
  The left coronary artery always branched off the left sinus of aorta. It divided into three branches in 7% of cases. The length of the anterior descending branch depended on the volume index of the heart. Gender was without significant effect on the dimensions of the left coronary artery.
  
  
  CONCLUSIONS
  Sexual dimorphism of the left coronary artery is weak and is not significant in most cases. The length of the anterior descending branch correlates with the volume index of the heart.
