Abstract

This study was aimed to obtain the anatomical information on the location of ostia of left and right coronary artery in 3 weeks old and 6 months old hybrid swine. The each intercommissural distance of 6 months group was twice than 3 weeks old group. The largest sinus was right aortic sinus followed by left and posterior sinus. All left coronary artery ostia in left aortic sinus were located near the right aortic sinus as well as lower than the ostia of right one. Most of the right coronary artery ostia were located at the level of supravalvular ridge of right aortic sinus. In addition the right ostia had more variation than left ones. Comparing to the sites of 3 weeks old pigs, the sites of the right ostia in 6 months group were more variable. These data suggest that the locations of coronary ostia were different with the sites of human's, and changes of the location may be occurred during the growth.
