Methods:Thirty heart specimens from cadaver of normal adult were studied. The dimensions of four levels inaortic root were measured and the relationships between the aortic sinues and its neighbouringstructure were observed. Results: The dimensions of four levels in aortic root obtained as follows;Sinus > STJ1 > STJ0 > Base (P < 0.05) . The dimensions of the aortic valve leaflets were measured.The right coronary leaflet was larger than those of the left coronary and noncor-onary leaflets .But there was no statistical signiftcane (P > 0.05) . The relationships between the middle axis ofthe anterior valve of the bicuspid valve and the aortic sinuses were examined. The middle axis ofthe anterior valve in 26 specimens (86.6%) located between the left coronary sinus and thenoncoronary sinus . The relationship between the aortic prominence of the right atrium and theaortic sinuses was examined. The aortic prominence was formed from noncoronary sinus in 22 specimens(73.3%) . The relationship between the middle point of the right and left pulmonary valves and theaortic sinuses was examined. The middle point of the right and left pulmonary valves in 24 specimens(80%) was faced to the point between the right and left aortic sinuses . Conclusion: The dimensionof the four levels in aortic root is as follows, sinus > STJ1 > STJ0 > Base (P < 0.05) . There wasno statistical significance in the size of the three aortic valve leaflets (P > 0.05).展开更多
