Congenital valvular aortic stenosis in young adults: predictors for rate of progression of stenosis and aortic dilatation.

Background: Congenital aortic stenosis (AS) is the most common obstructive left-sided cardiac lesion in young adults, however little is known about the progression in adults. Therefore, we aimed to evaluate the progression rate of AS and aortic dilatation in a large multicenter retrospective cohort of asymptomatic young adults with congenital valvular AS.

Methods: Data were obtained from chart abstraction.
