Plain-English summary
A 4-year-old male neutered English bulldog was taken to the vet for a heart murmur. Tests showed he had severe narrowing of the pulmonary valve and an unusual coronary artery that could cause serious problems. Before attempting to implant an artificial valve, the vet performed a test to check for potential issues with the blood supply. Unfortunately, they found that one of the arteries was completely blocked, leading them to cancel the valve surgery due to the risk of life-threatening complications.

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.
