The authors, continuing their work concerning the tricuspid valve which was communicated at the Fourth European Anatomical Meeting (Bále, 1977), now present a study of twenty anatomical preparations according to the Mac ALPINE technique of perfusion-fixation, giving to the preparation a morphology comparable to that of the heart at the end of the diastole. The present work consists in a descriptive and morphological study of one type of tendinous cord, not described until now, and denominated mixed cord. It defines itself by its valvular insertions which are situated on the four areas of the tricuspid valve described by SILVER and al. It is a cylindric tendinous cord, always ramified either into two branches which are in turn greatly ramified, or into a fan shaped spreading. Each ramification is attached to the valve by an expansion which is either perpendicular or parallel to the ring. This work specifies: the number of tendinous cords, their distribution to the three cusps of the tricuspid valve, the number of their ramifications and their valvular insertions.
作者们继续他们关于三尖瓣的研究工作（该研究在第四届欧洲解剖学会议上进行了交流，地点：巴勒，1977年），现在根据麦克阿尔派恩灌注固定技术对20个解剖标本进行了研究，使标本呈现出与舒张期末心脏形态相似的形态。目前的工作包括对一种迄今为止尚未描述过的腱索类型进行描述性和形态学研究，这种腱索被命名为混合腱索。它通过其瓣膜附着点来定义自身，这些附着点位于西尔弗等人所描述的三尖瓣的四个区域。它是一种圆柱形腱索，总是分支为两个分支，这两个分支又会进一步大量分支，或者呈扇形展开。每个分支通过一个与瓣膜环垂直或平行的扩张部分附着在瓣膜上。这项工作明确了：腱索的数量、它们在三尖瓣三个瓣叶上的分布、它们分支的数量以及它们在瓣膜上的附着点。
