Plain-English summary
A 1.5-year-old female French Bulldog was diagnosed with severe heart problems, specifically a narrowing of the pulmonary valve and an unusual coronary artery structure. She showed signs of right-sided heart failure, which means her heart was struggling to pump blood effectively. Despite receiving medical treatment for six months, her condition worsened, and her owners chose to euthanize her. A post-mortem scan confirmed the heart's abnormal structure, which could have made surgery difficult if it had been attempted.

Abstract
A 1.5-year-old female French Bulldog was diagnosed with severe valvular pulmonic stenosis, coronary artery anomaly, and clinical signs of right-sided heart failure. Despite medical management, the patient’s condition deteriorated, and euthanasia was elected after 6 months of treatment. Post-mortem contrast-enhanced computed tomography additionally revealed a single right coronary ostium and confirmed a prepulmonary course of the left coronary artery, consistent with an R2A-type coronary anomaly. This anomaly could have significantly complicated potential surgical or catheter-based interventions on the right ventricular outflow tract in patients with pulmonic stenosis. Contrast-enhanced post-mortem computed tomography enabled non-destructive, reproducible 3D visualization of the coronary course and its spatial relationship to the RVOT before dissection. This approach can complement conventional necropsy by enhancing anatomical documentation, communication, and targeted sampling in cases of complex congenital cardiovascular anomalies.
