Popis: Objective. The present paper aims to investigate the role of computed tomography as an imaging technique of diagnosis in the identification of the os cordis in ovine, and also how this anatomical structure is morphotopographically characterized in macro and microscopic contexts, seeking to contribute for its functional understanding. Materials and method. The heart of a young male ovine had been donated to the Laboratory of Animal Anatomy of the Surgery Department of the FMVZ/USP, first being subject to a post-mortem examination by means of the cardiac “shedding” (transverse cross sectioning of the heart). A tomographic examination of the anatomic specimen was carried out, as well as the dissection and histological analysis of the collected sample. Results. The results indicate the presence of an osseous structure of 6.39 mm in length, located in the aortic valve of the heart, next to a ring comprised by three valve flaps, tendinous cords, and papillary muscles. The histological findings consist of fibrous connective tissue, cancellous bone tissue, and calcified hyaline cartilage wherein the cardiomyocytes are attached. Conclusions. It is concluded that computed tomography, even though seldom applied to animals of zootechnical interest, poses as an effective tool for the visualization of the os cordis in lambs.
