The anomalous tendinous cord in right atrioventricular valve in mongreel dogs (Canis familiaris L. 1758)
Keywords:Chordae tendineal, Heart, Dogs
AbstractAccomplishing observations for description of the anatomical types of the tendinous cords and papillar muscles in a group of 40 hearts of crossbred dogs, it came across two types of tendinous cords quite uncommon. In the literature, few reports of anomalies of the tendinous cords in animals were found and none of them showed any likeness with the results described in this case. The first type was a rope of retrograde direction whose origin is in the muscular tissue that garnishes the fibrous annulus. Its filament, after crossing the right atrioventricular anullus, joined to a bundle of common cords originating from the magnus papillar muscle. The second type was the most unusual. It was a cord with 5.3 cm of length, from the subarterious papillar muscle to the intermediate semilunar valve in the pulmonary artery. Its insertion in this artery settled down as a "liaison" that allowed to be tightened.
