The heart, as we know, is a muscular tissue supported by collagenous structures forming the fibrous skeleton of the heart. A structure by the name of the tendon of infundibulum appeared in the literature with no definite information about its structure or even its existence. The tendon of infundibulum was described as a strip of fibrous tissue structure situated between the aortic root and pulmonary trunk. Our study involved 30, formalin fixed, adult human hearts ranging from 18 to 81 years. Classical macroscopic anatomical methods were applied to observe macroscopically all the connections between the aorto-pulmonary trunk, together with serial transverse histological sections, through roots of the aorta and pulmonary trunk, using eosin-hematoxylin and van Gieson staining. All the hearts seemed to encompass many fascial bands attended by connective tissue. However these fascial bands are not concrete structures and cannot be termed tendons. In our investigation we have been unable to demonstrate macroscopically or histologically any structure which could be significantly approximating to the initial description of the literature. However, as far as we are able to judge, the term tendon of infundibulum has erroneously been introduced into many medical textbooks since the literature cannot still prove its existence.
我们知道，心脏是一种肌肉组织，由构成心脏纤维骨架的胶原结构支撑。文献中出现了一个名为漏斗腱的结构，但关于其结构甚至其是否存在都没有确切信息。漏斗腱被描述为位于主动脉根部和肺动脉干之间的一条纤维组织结构带。我们的研究涉及30颗经福尔马林固定的成人心脏，年龄在18至81岁之间。应用经典的宏观解剖方法，通过主动脉和肺动脉干的根部，使用苏木精-伊红染色和范吉森染色，对主动脉-肺动脉干之间的所有连接进行宏观观察，并制作连续的横向组织切片。所有的心脏似乎都包含许多伴有结缔组织的筋膜带。然而，这些筋膜带并非具体结构，不能称为肌腱。在我们的研究中，无论是宏观上还是组织学上，我们都未能证明有任何结构能与文献最初的描述显著相符。然而，就我们所能判断的而言，由于文献仍无法证明漏斗腱的存在，这个术语却错误地被引入了许多医学教科书中。
