Williams syndrome is a genetic disorder caused by multiple gene deletions on chromosome 7. The majority of the cases is sporadic and has typical facial appearance, cardiac anomalies and mental retardation. Cardiovascular anomalies are present in about 80% of the cases, most frequently supravalvular aortic stenosis and pulmonary arterial stenosis. In this article, we report two pediatric cases with a rapidly progressive form of aortic coarctation, each of whom required two surgeries and two percutaneous balloon dilatations within the first five months of life.
