本文对75例成人正常心脏的主动脉瓣及其毗邻结构作了观察和测量,并作了探讨,现将所得结果报告如下:1.主动脉的左瓣平均高度为1.25±0.02厘米,平均宽为2.11±0.03厘米,平均面积为2.30±0.09平方厘米,右瓣的平均高度为1.26±0.02厘米,平均宽度为2.27±0.03厘米,平均面积为2.36±0.09平方厘米;后瓣的平均高度为1.29±0.03厘米,平均宽度为2.21±0.03厘米,平均面积为2.29±0.09平方厘米.2.主动脉瓣新月区出现园形、椭圆形或梭形筛状小孔者,左瓣出现9例(12.00±3.75%),右瓣出现13例(17.30±4.38%),后瓣出现12例(16.00±4.23%).3.主动脉瓣环的上周径平均为6.61±0.03厘米,下周径平均为7.05±0.09厘米.上周径面积与三个瓣膜总面积之比平均为1:1.74.4.主动脉窦的高度,左窦平均为1.88±0.04厘米,右窦平均为1.89±0.03厘米;后窦平均为1.82±0.03厘米.此外,我们尚对主动脉窦与冠状动脉开口的位置关系作了探讨,提出了作者的观点.5.主动脉的瓣间三角,左后三角的平均高度为1.20±0.02厘米,低宽平均为1.79±0.03厘米;右后三角的平均高度为1.23±0.02厘米,低宽平均为1.71±0.03厘米;左右三角的平均高度为1.17±0.03厘米,低宽平均为1.62±0.03厘米.
In this paper, 75 cases of normal adult aortic valve and its adjacent structures were observed and measured, and discussed, the results are reported as follows: 1. aorta left flap average height of 1.25 ± 0.02 cm, the average width Was 2.11 ± 0.03 cm with an average area of 2.30 ± 0.09 cm 2 and an average height of 1.26 ± 0.02 cm with an average width of 2.27 ± 0.03 cm and an average area of 2.36 ± 0.09 cm 2 with an average height of 1.29 ± 0.03 cm, the average width of 2.21 ± 0.03 cm, with an average area of 2.29 ± 0.09 square centimeter .2 aortic valve crescent appear circular, oval or spindle sieve-like hole, the left flap in 9 cases ( 12.00 ± 3.75%), the right flap appeared in 13 cases (17.30 ± 4.38%), the posterior flap appeared in 12 cases (16.00 ± 4.23%) .3.The average diameter of the aortic annulus was 6.61 ± 0.03 cm, With an average of 7.05 ± 0.09 cm.The ratio of the area of the last week to the total area of the three valves was 1: 1.74.4.The average aortic sinus height was 1.88 ± 0.04 cm for the left sinus and 1.89 ± 0.03 cm for the right sinus ; Posterior sinus average of 1.82 ± 0.03 cm. In addition, we still on the aortic sinus and coronary ostial opening was discussed the relationship between the position The author’s point of view.5.Aortic aortic trigonometry, the average height of the left posterior triangle is 1.20 ± 0.02 cm, the average width of 1.79 ± 0.03 cm; the average height of the right rear triangle is 1.23 ± 0.02 cm, the average width of low 1.71 ± 0.03 cm; the average height of the left and right triangles was 1.17 ± 0.03 cm, and the average width was 1.62 ± 0.03 cm.
