Abstract
Aberrant origin of the coronary arteries from the pulmonary trunk were observed in 15 (2.0%) of 733 bovine hearts showing congenital cardiovascular anomalies. The incidence of this anomaly in cattle necropsied at Miyazaki University was 0.17%. Anomalous coronary arteries originated from the pulmonary trunk were left coronary artery (7 cases), right coronary artery (5 cases), left and right coronary arteries (1 case), single coronary artery (1 case) and paraconal interventricular branch of left coronary artery (1 case).
