RESUMO
A two-year-old, male castrated, French bulldog was presented for evaluation of coronary artery anatomy before balloon valvuloplasty for severe pulmonic valve stenosis. Multidetector computed tomography angiography showed a single left coronary ostium, absent right coronary ostium, and an anomalous, prepulmonic coursing right coronary artery. Medical management was elected to avoid the attendant risk associated with intervention. This case report documented the first known case of this specific anomaly in French bulldogs. Veterinary cardiologists should be aware of the potential for this specific coronary artery anomaly in this breed, given the predilection for the development of pulmonary stenosis. Routine screening of French bulldogs for anomalous, prepulmonic coronary arteries is recommended before interventional balloon valvuloplasty.
