Abstract

Background: The coronary vessels have been described in various species of domestic and wild ruminants. However, no studies on the detailed morphology and morphometry of heart orifices and coronary ostia in the Polish goat are available.

Materials and methods: The study was carried out on 112 female, adult dairy goats belonging to Polish Fawn Improved and Polish White Improved breed, closely related to French Alpine and Saanen, respectively.

Results: In all examined individuals, all heart orifices and heart valves were of normal structure. There was no significant difference between diameter of the aortic and pulmonary orifice. The right atrioventricular opening was significantly wider than the left atrioventricular opening. The dimension of the left coronary ostium ranged from 1.0 to 5.5 mm with the arithmetic mean (± standard deviation [SD]) of 4.3 ± 0.8 mm. The dimension of the right coronary ostium ranged from 0.5 to 5.0 mm with the arithmetic mean (± SD) of 2.8 ± 0.7 mm. Both coronary artery ostia were located under the sinotubular junction. Out of 112 examined goats, 39 (34.8%) had variations in the structure of the coronary ostia such as the lack of main trunk or the presence of additional coronary ostia. They were observed in one (in 34/39 goats) or both coronary arteries (5/39 goats).

Conclusions: In goats, the dimensions of aortic and pulmonary orifices are similar while the right atrioventricular opening outsizes the left one. On the other hand, the left coronary ostium is wider than the right one. Morphological variations in the coronary ostia occur in approximately one third of goats, more often in the right than in the left ostium.

山羊心脏口的形态测量以及冠状动脉口的形态和地形图。
背景:冠状血管在各种家养和野生反刍动物中都有描述。然而,目前还没有关于波兰山羊心脏孔和冠状动脉口的详细形态和形态测量的研究:研究对象是 112 只成年雌性奶山羊,它们分别属于波兰黄褐色改良品种和波兰白色改良品种,与法国阿尔卑斯山羊和萨能山羊密切相关:所有受检个体的所有心脏孔和心脏瓣膜结构均正常。主动脉瓣口和肺动脉瓣口的直径没有明显差异。右房室口明显比左房室口宽。左冠状动脉口的尺寸在 1.0 至 5.5 毫米之间,算术平均值(± 标准差 [SD])为 4.3 ± 0.8 毫米。右冠状动脉口的尺寸范围为 0.5 至 5.0 毫米,算术平均值(± 标准差 [SD])为 2.8 ± 0.7 毫米。两个冠状动脉口均位于窦管交界处下方。在 112 只接受检查的山羊中,有 39 只(34.8%)山羊的冠状动脉口结构存在变异,如缺少主干或存在额外的冠状动脉口。结论:在山羊中,冠状动脉孔的尺寸与山羊的体型有关:结论:山羊的主动脉口和肺动脉口的尺寸相似,而右侧房室开口大于左侧开口。另一方面,左冠状动脉口比右冠状动脉口宽。大约三分之一的山羊冠状动脉口存在形态变化,右侧冠状动脉口比左侧多。

期刊介绍: "Folia Morphologica" is an official journal of the Polish Anatomical Society (a Constituent Member of European Federation for Experimental Morphology - EFEM). It contains original articles and reviews on morphology in the broadest sense (descriptive, experimental, and methodological). Papers dealing with practical application of morphological research to clinical problems may also be considered. Full-length papers as well as short research notes can be submitted. Descriptive papers dealing with non-mammals, cannot be accepted for publication with some exception.
