          Abstract

          Dextrocardia is a rare cardiac anomaly where the heart is situated on the right antimeres of the thorax. This study had the objective of describing a case of dextrocardia with situs solitus and apex-basis axis inversion in a lesser anteater (Tamandua tetradactyla) between five evaluated animals, all from the area of Mine Bauxite - Paragominas - Para. The arterial system was filled with contrasted latex and the animals were fixed with 10% formaldehyde and a posterior dissection was done. The heart of an animal was found in right antimere with inversion of the base-apex axis. The right atrium was more developed then the left and the pulmonary veins arrived directly in the left ventricle. The main vases of the base were identified with some topographic alterations resulting in: aorta dorsal to the cava caudal vein, pulmonary artery dorsal and cranial to aorta, pulmonary veins ventral to the pulmonary artery, cava caudal vein in ventral plain and cava cranial vein in dorsal plan in relation to the other vessels. Internally there were four cardiac chambers, with absence of septal communication.

          Dextrocardia é uma anomalia cardíaca rara no qual o coração está situado no antímero direito do tórax. Este estudo objetivou descrever um caso de dextrocardia com situs solitus e inversão do eixo ápice-base em um tamanduá-mirim (Tamandua tetradactyla), entre cinco animais avaliados, sendo todos da área da mina de bauxita - Paragominas - Pará. O sistema arterial foi preenchido com látex contrastado e os animais foram fixados com formol a 10% e seguido de dissecção posterior. O coração de um dos animais foi encontrado no antímero direito com inversão do eixo ápice-base. O átrio direito era mais desenvolvido do que o esquerdo e as veias pulmonares chegaram direto no ventrículo esquerdo. Foram identificados os principais vasos da base com alterações topográficas, resultando em: aorta dorsal à veia cava caudal, artéria pulmonar dorsal e cranial da aorta, veias pulmonares ventrais a artéria pulmonar, veia cava caudal em plano ventral e veia cava cranial em plano dorsal em relação a outros vasos. Internamente foram localizadas quatro câmaras cardíacas, com ausência de comunicação septal
