目的：为了讨论几何因素，这可能会影响长期的结果有关的同种移植物的能力后，罗斯程序，我们描述了肺动脉和主动脉根部的三维形态。材料：对25例人主动脉和肺动脉根部进行了测量。测量连合间距离和窦的高度。在几何重建中，三个连合及其在牙根底的垂直投影被用作参考点。结果如下：在肺根中，三个连合间距离的尺寸相似（17.9 +/- 1.6 mm、17.5 +/- 1.4 mm和18.6 +/- 1.5 mm）。在主动脉根中，右侧连合间距离最大（18.8 +/- 1.9 mm），其次是非冠状窦连合（17.4 +/- 2.0 mm）和左侧冠状窦连合（15.2 +/- 1.9 mm）。左肺静脉窦的平均高度最高（20 ± 1.7 mm），其次是前肺静脉窦（17.5 ± 1.4 mm）和右肺静脉窦（18 ± 1.66 mm）。在主动脉根部，右冠状窦的高度最高（19.4 ± 1.9 mm），其次是非冠状窦（17.7 ± 1.8 mm）和左冠状窦（17.4 ± 1.4 mm）。测量的参数之间的差异确定根向量的倾斜角度和方向。肺动脉根部的倾斜角平均为16.26度，主动脉根部为5.47度。结论：因此，我们建议最好将左肺静脉窦植入右冠状静脉窦，将前肺静脉窦植入非冠状静脉窦，将右肺静脉窦植入左冠状静脉窦。以这种方式，肺根向量的方向将平行于主动脉根向量的方向。(c)2007年欧洲胸外科协会。Elsevier B.

Objective: To discuss geometric factors, which may influence long-term results relating to homograft competence following the Ross procedure, we describe the 3D morphology of the pulmonary and aortic roots. Materials: Measurements were made on 25 human aortic and pulmonary roots. Inter-commissural distances and the heights of the sinuses were measured. For geometrical reconstruction the three commissures and their vertical projections at the root base were used as reference points. Results: In the pulmonary root, the three inter-commissural distances were of similar dimensions (17.9 +/- 1.6 mm, 17.5 +/- 1.4 mm and 18.6 +/- 1.5 mm). In the aortic root, the right inter-commissural distance was greatest (18.8 +/- 1.9 mm), followed by the non-coronary (17.4 +/- 2.0 mm) and left coronary sinus commissures (15.2 +/- 1.9 mm). The mean height of the left pulmonary sinus was greatest (20 +/- 1.7 mm) followed by the anterior (17.5 1.4 mm) and right pulmonary sinus (18 +/- 1.66 mm). In the aortic root, the height of the right coronary sinus was the greatest (19.4 +/- 1.9 mm) followed by the heights of the non-coronary (17.7 +/- 1.8 mm) and left coronary sinus (17.4 +/- 1.4 mm). Measured differences between parameters determine the tilt angle and direction of the root vector. The tilt angle in the pulmonary root averaged 16.26 degrees, respectively; for the aortic roots, it was 5.47 degrees. Conclusions: Herein we suggest that the left pulmonary sinus is best implanted in the position of the right coronary sinus, the anterior pulmonary in the position of the non-coronary sinus and the right pulmonary sinus in the position of the left coronary sinus. In this way, the direction of the pulmonary root vector will be parallel to that of the aortic root vector. (c) 2007 European Association for Cardio-Thoracic Surgery. Published by Elsevier B.V.
