The coronary arteries of the goats have been used to researches about to pharmacological actions, heart failure after connection of coronary arteries and others. Twenty-seven goat hearts, both sexes, fixed in formalin at 10% has been used in this study that analyzed the coronary arteries pattern in goats and if the same is similar to the human coronary arteries pattern. The left coronary artery is dominant and in relation to the length demonstrated average 1.15cm emitting two branches: interventricular paraconalis and circumflex. The interventricular paraconalis branch with average length 10.5cm issued branches to the both ventricles fairly, ending more frequently in the interventricular subsinuosis sulcus. The circumflex branch with average length 8.5cm issued branches to left ventricle and right atrium fairly. The left marginal branch is not constant. The right coronary artery, with average length 6.1cm issued branches to right ventricle and right atrium fairly, but the interventricular subsinuosis branch with average length 3.1cm is variable and can present one long branch, one short branch or one double branch, with the huge part for the right ventricle. |
