Noonan syndrome is the second most frequent congenital malformation syndrome, after Down syndrome, associated with cardiovascular abnormalities. The most prevalent cardiovascular abnormalities in Noonan syndrome are pulmonary stenosis and hypertrophic cardiomyopathy. We report the case of a 12-year-old girl with Noonan syndrome who had multiple cardiovascular abnormalities, including extensive bilateral coronary artery dilatation, valvular and supravalvular pulmonary stenosis, atrial septal defect, and mitral valve prolapse. Both coronary artery dilatation and supravalvular pulmonary stenosis, although rarely reported, are abnormalities of the cardiovascular system that may occur in Noonan syndrome.
