Diagnosis and treatment of heart diseases due to changes in the coronary vascularization need a detailed knowledge on the morphology and possible variations of the aortic valves and coronary ostia. This study was performed to clarify details on morphology of these structures in domestic cats. The tricuspid aortic valve was examined in 65 domestic shorthair cats. The location of coronary ostia was determined either inferior to (26 and 20%, left and right coronary ostium - LCO and RCO), at (65 and 66%) or superior to the intercommissural line (9 and 14%). In 13 cats (20%), accessory ostia were found either for left, right or both coronary arteries (LCA and RCA). Their position varied between specimens. They were located beyond the main ostium, at its edge, or inside just below the edge. In one cat, no main trunk of the LCA was found. In one cat, two accessory ostia next to the RCO were observed. Coronary ostia in cats show anatomical variants and morphological anomalies. This study provides basic data useful for, for example, angiography performed for diagnosis of cardiac diseases and as a basis for surgical interventions.
由于冠状动脉血管化改变所致心脏病的诊断和治疗需要详细了解主动脉瓣和冠状动脉口的形态及可能的变异情况。本研究旨在阐明家猫这些结构的形态细节。对65只家养短毛猫的三尖瓣主动脉瓣进行了检查。冠状动脉口的位置确定为在连合间线下方（左冠状动脉口和右冠状动脉口分别为26%和20%）、在连合间线上（分别为65%和66%）或在连合间线上方（分别为9%和14%）。在13只猫（20%）中，发现了左冠状动脉、右冠状动脉或两者（左冠状动脉和右冠状动脉）的副口。它们的位置在不同标本间有所不同。它们位于主口之外、主口边缘或刚好在边缘下方内部。在一只猫中，未发现左冠状动脉主干。在一只猫中，观察到右冠状动脉口旁有两个副口。猫的冠状动脉口显示出解剖变异和形态异常。本研究提供了有用的基础数据，例如可用于心脏病诊断的血管造影以及作为手术干预的依据。
