SANTOS, José Wilson dos et al. Myocardial bridges in bovine of the Canchim race. Braz. J. Vet. Res. Anim. Sci. [online]. 2000, vol.37, n.2, pp.00-00. ISSN 1413-9596. http://dx.doi.org/10.1590/S1413-95962000000200006.
It was studied 30 hearts of adult Bos taurus, females of the race Canchim, with the objective of observing the frequency, width, location and angulation of the myocardial bridges. For the macroscopic study the hearts had injected the coronary arteries with solution of Neoprene red-faced latex 450, with posterior fixation in aqueous solution of formol to 10% and after dissection. The results indicate that the myocardial bridges happen in 100% of the hearts, with medium width of 1.24 cm and they locate more commonly in the portions average (38.87%), ventral (26.11%). Multiple bridges are observed in 93.33% of the hearts varying from two to six. The muscular fibers of the segment form angles with the longitudinal axis of the arterial vases with medium of 46º.
