Anatomical pattern of the Chordae tendineae in Landrace pigs
Keywords:Anatomy of swine, Heart
Hearts of 20 male and 20 female, adult Landrace pigs, was examinated, to study the number and disposition of the Chordae tendineae relating to atrioventricular valve. The hearts, after cleaning of the cavities, were fixed in formalin; after that procedure the atrial wall and, partially, the ventricular wall were removed, preserving "in situ" the components of the left valvar complex. It was reported five different morphological types of Chordae, reunited in two groups: comissural Chordae and cuspidal Chordae, this with four types. It was also studied, the number, disposition and the frequence of the Chordae tendineae that emerging from a certain papillary muscle, arrive to one or more than one cuspid.
