6. Chest Pain
In most cases, chest pain in children is not related to heart problems. Unfortunately, some children are born with cardiac abnormalities (congenital) that may cause chest pain as a symptom. For instance, roughly 75% of children with Williams syndrome are born with congenital heart defects.2Ko, Jung Min. (2015). Genetic Syndromes associated with Congenital Heart Disease. Korean circulation journal. 45. 357-61. 10.4070/kcj.2015.45.5.357. Specifically, supravalvar aortic stenosis is the most frequent heart defect seen in these patients.
In supravalvar aortic stenosis, the main artery that leaves the lower left chamber of the heart (aorta), becomes unusually narrow (stenosis) in the area above the aortic valve. According to the degree of narrowing of the aorta, symptoms like chest pain, fatigue, dizziness, and temporary loss of consciousness can develop. Other possible cardiac lesions in this syndrome include pulmonary stenosis and mitral valve regurgitation.
