Abstract

A 4-year-old male neutered English bulldog presented for heart murmur evaluation. Echocardiography identified severe pulmonic stenosis (an echocardiography-derived transpulmonary pressure gradient of 100 mmHg), and computed tomography confirmed the presence of an anomalous coronary artery with a prepulmonic course of the left coronary artery arising from the right coronary ostium. Before artificial pulmonic valve implantation, a coronary compression test was performed. A simultaneous aortic root angiogram and pulmonic balloon valvuloplasty revealed complete occlusion of the circumflex branch. Artificial valve implantation was aborted with concern for fatal coronary compression after implantation. Coronary compression testing is a critical component of the evaluation before catheter-based implantation of conduits across the pulmonic valve.
