The interest in experimental use of coronary arteries of swine as a stage towards their application in human hearts justifies the need for obtaining a detailed anatomical understanding of those arteries, particularly to evaluate similarities and differences. However, we did not find any citations about anatomical indicators of coronary dominance among swine in the literature. Many authors have used the crux cordis and the origin of the posterior interventricular branch as references for defining three types of pattern in human hearts: right, balanced and left dominance. We used 30 hearts fixed in 10% formalin from male and female Landrace swine aged five to six months, weighing 80 to 110 kg. The branch corresponding to the subsinuosal interventricular sulcus came from the right coronary artery (96.7%) or from both coronary arteries (3.3%). The subsinuosal interventricular branch presented at least one small branch that went beyond the crux cordis. The apical area presented predominance of the paraconal interventricular (left anterior descending) branch in 43.3%, the subsinuosal interventricular branch in 23.3% and presence of both arteries in 33.3%. The left coronary artery emitted 54.5% of the ventricular branches and the right coronary artery 46.5%. Taking the crux cordis and the subsinuosal interventricular branch as references, the arterial pattern in swine hearts is right dominance. The diversity of the apical pattern and the balance in the distribution of ventricular branches do not allow this to be used as an approach in isolation. The similarities between human and swine hearts also apply to the coronary artery pattern.
将猪的冠状动脉用于实验，以此作为应用于人类心脏的一个阶段，这种兴趣证明了详细了解这些动脉解剖结构的必要性，特别是为了评估异同。然而，我们在文献中未发现任何关于猪冠状动脉优势解剖指标的引用。许多作者将心脏十字交叉和后室间支的起源作为定义人类心脏三种类型模式的参考：右优势、均衡优势和左优势。我们使用了30颗用10%福尔马林固定的心脏，来自5至6个月大、体重80至110千克的长白猪，雌雄不限。与室下间沟相对应的分支来自右冠状动脉（96.7%）或来自两支冠状动脉（3.3%）。室下间支至少有一个小分支超出心脏十字交叉。心尖区域，圆锥旁室间（左前降支）占优势的为43.3%，室下间支占优势的为23.3%，两支动脉均有的为33.3%。左冠状动脉发出54.5%的室支，右冠状动脉发出46.5%。以心脏十字交叉和室下间支为参考，猪心脏的动脉模式为右优势。心尖模式的多样性和室支分布的均衡性不允许单独将其作为一种方法。人类和猪心脏之间的相似性也适用于冠状动脉模式。
