Congenital aortic valve stenosis

Disease definition

A rare aortic malformation of variable severity and clinical presentation. Clinical presentations range from a neonatal severe presentation often associated with sudden cardiac death, to a slowly progressive stenosis that presents later with cardiac murmur, chest pain, dizziness, and loss of consciousness with exercise-induced exacerbations. Echocardiography reveals atresia or dysplasia of the aortic valve most commonly associated with a bicuspid morphology, restricted left ventricular outflow, and left ventricular hypertrophy.
