- W289802123 abstract "espanolA menudo se describe que la trabecula septomarginal derecha del corazon de las cabras presenta cuerdas tendinosas. Sin embargo, en nuestras disecciones este no es un hallazgo frecuente en otras especies animales y el presente trabajo se diseno para comprobar si las cuerdas tendinosas en esta especie se originan directamente del tabique interventricular. El material utilizado fueron 32 corazones de cabras de ambos sexos, de raza mestiza, conservados en formol al 10%. El ventriculo derecho se abrio mediante un corte en el punto central del tronco pulmonar y continuando a traves del cono arterioso hasta el borde derecho. Nuestros resultados mostraron que 68,8% de los corazones presentaban al menos una larga cuerda tendinosa saliendo de la trabecula septomarginal. El origen fue predominantemente en el tercio de la trabecula cerca del tabique (58,3%), destinadas a la valva septal y fi jas en su borde libre (87,5%). La presencia de cuerdas tendinosas originandose directamente del lado derecho del tabique interventricular se observo en 59,4% de los corazones. Estas son cortas aunque predominan en la region craneodorsal del tabique interventricular (76,7%). Ellas se fi jan a la valva septal (96,8%) y estan destinadas al borde libre (80%). La presencia de cuerdas tendinosas en la trabecula septomarginal no tiene relacion con la presencia o ausencia de las cuerdas tendinosas en el tabique. EnglishThe right septomarginal trabecula in goats frequently presents tendinous chords emerging from it. Since we had not observed such great occurrences in any other animal in which we had investigated the trabecula, we decided to conduct this study with the aim of establishing possible relationships with tendinous chords that emerge directly from the interventricular septum. The material used consisted of 32 hearts from non-pedigree goats of both sexes, conserved in 10% formalin. The right ventricle was opened by means of an incision starting at the central point of the pulmonary trunk and continuing through the arterial cone to the right margin. Our results demonstrated that 68.8% of the specimens presented at least one long tendinous cord emerging from the septomarginal trabecula. This emergence occurred predominantly in the third of the trabecula closest to the septum (58.3%) and the cord headed to the septal cusp and attached to its free margin (87.5%). The presence of tendinous chords emerging directly from the right side of the interventricular septum was found in 59.4% of the specimens. These were short, because they were predominantly in the craniodorsal region of the interventricular septum (76.7%). They attached to the septal cusp (96.8%) and headed for the free margin (80%). The presence of tendinous chords in the septomarginal trabecula was unrelated to the presence or absence or tendinous chords in the septum." @default.
