An anatomical study of the tricuspid valve was carried out in 50 human hearts of both female and male individuals using a method of dissection which preserves the integrity of the valve. Morphometric criteria such as area of cusp, width of cusp base, relation between commissure depth and cusp depth and morphological criteria such as the presence of atrioventricular cusp node, number of tendinous cords, perimeter of fibrous ring, and properties of papillary m. were adopted for characterization of a cusp. In 64% of cases, commissural cusps were present independent of the number of tricuspid cusps. The tricuspid valve was not consistently tricuspid, but was observed to present 2, 4, 5 or 6 cusps in 72% of cases.
采用一种能保持瓣膜完整性的解剖方法，对50例男女个体的人心脏三尖瓣进行了研究。采用诸如瓣叶面积、瓣叶基部宽度、瓣叶联合深度与瓣叶深度的关系等形态测量标准，以及诸如房室瓣叶结节的存在、腱索数量、纤维环周长和乳头肌特性等形态学标准来表征瓣叶。在64%的病例中，瓣叶联合存在，与三尖瓣叶的数量无关。三尖瓣并非始终为三尖瓣，而是在72%的病例中观察到有2、4、5或6个瓣叶。
