This study was carried out to describe the ramifications of the cardiac veins of Angora rabbit. For this purpose, a total of 16 adult healthy Angora rabbits of both sexes, 1.5-2 years of age, were used. The great, middle, right cardiac veins ran in a subepicardial course and opened into the left cranial vena cava, but some tributaries of the right cardiac veins sometimes also joined various portions of the right atrium. The smallest cardiac veins followed subendocardially and terminated in the right chambers of the heart. Based on their origin, course and frequency, it was concluded that the smallest cardiac veins are primarily responsible for the drainage of the interventricular septum. Results from this study are thought to shed light on further heart-related medical studies, and to contribute considerably to the present anatomical knowledge of the cardiac veins in this species. © 2007 The Authors.
