Twenty hearts of adult ovines, seventeen males and three females had been studied, of the Ideal race, without apparent cardiac pathology, with the objective to observe the frequency and the width, as well as the location, of the myocardium bridges. For the macroscopic study the hearts had had its coronary arteries injected with Neoprene solu¬tion latex 450, and after had been fixed in watery solution of Formol 10%. It was verified that the myocardium bridges had occurred in 100% of the observed hearts, with width varying of 1,10cm 6,25cm, average of 2,28cm; in ventricles with average height of 7,82cm. It was also verified that most of the myocardium bridges had occurred in 96% in the paraconal branch of the left coronary artery and in 4 % in the circumflexus branch of the same one. KEY-WORDS: Anatomy, heart, myocardium bridges, ovines.
Estudaram-se vinte corações de ovinos adultos, de¬zessete machos e três fêmeas, da raça Ideal, sem aparente comprometimento ou doença cardíaca, a freqüência e a largura, bem como a localização, das pontes de miocárdio. Para o estudo macroscópico, os corações tiveram suas ar¬térias coronárias injetadas com solução de Neoprene látex 450, e após foram fixados em solução aquosa de formol a 10%. Verificou-se que as pontes de miocárdio ocorreram em 100% dos corações observados, com largura variando de 1,10cm a 6,25cm, média de 2,28cm; em ventrículos com altura média de 7,82 cm. Verificou-se também que a maior parte das pontes de miocárdio ocorreu, em 96%, no ramo paraconal da artéria coronária esquerda e em 4 % no ramo circunflexo dessa artéria. PALAVRAS-CHAVES: Anatomia, coração, ovinos, pontes de miocárdio.
