Pulmonic stenosis is the third most common cardiac congenital defect (18%) behind patent ductus arterosis (32%) and aortic stenosis (22%) 1. Currently the preferred method of treatment for pulmonic stenosis is balloon valvuloplasty. There has been several cases documented in which an English bulldog has undergone valvuloplasty that has resulted in sudden death2, 3, 4. During the necropsy it was discovered that the sudden death was the result of a ruptured coronary artery that was anomalous with the left coronary branch coming of the right and wrapping around the pulmonary trunk. In this article we report on a balloon valvuloplasty being preformed on an English bulldog with an aberrant coronary artery.
