Abstract

Isolated aortic regurgitation and myocardial infarction are a rare congenital defect among neonatal patients. We present a case of a neonate with an unusual aortic valve morphology causing both regurgitation and obstruction of the left coronary artery ostium. Despite both non-invasive and invasive imaging modalities, accurate diagnosis of the valve morphology was only determined by direct visualisation at the time of surgical repair. To the knowledge of authors, this particular aortic valve morphology in neonatal population has not been previously reported in the literature.
