We report an 8-year-old female undergoing interventional catheterization for treatment of pulmonary artery stenoses, atrial septal defect and patent ductus arteriosus. Anomalous left coronary artery arising from the pulmonary artery was diagnosed during the procedure. We highlight the importance of recognizing this rare anomaly to avoid the risk of myocardial ischaemia consecutively to abrupt decrease of right ventricular pressure after dilation of pulmonary branches.
