The purpose of this study was to investigate and compare the morphology of tendinous chords which played an important role on the function of the left ventricle of human and animal hearts (such as dog, sheep, goat).
Eighty-one hearts (8 human, 23 dog, 25 sheep, 25 goat) were investigated in this study. The number of the tendinous chords which were attached from the anterior and posterior papillary muscles to anterior and posterior cusps and anterolateral and posteromedial commissures were considered.
The number of the tendinous chords which originated from anterior papillary muscle varied between 3 and 14, and from posterior papillary muscle varied between 3 and 17 in the species included.
The number of the tendinous chords begining from anterior and posterior papillary muscles and ending at anterior and posterior cusps varied between 2-14 and 4-16, respectively.
The tendinous chords originating from the anterior papillary muscle were not attached to posteromedial commissure, and those originating from the posterior papillary muscle were not attached to anterolateral commissure.
As a result of this study, the number of the tendinous chords in human heart were high (p<0.0001), and dog heart was considered to be a better model for the human heart, than sheep or goat.Keywords: Morphology, Tendinous chord, Left ventricle, Species differencesTurkiye Klinikleri J Med Sci 2001, 21:459-466
