title: Asymptomatic double site of left ventricular outflow tract obstruction: subvalvular aortic stenosis associated with valvular aortic stenosis.
abstract: Left ventricular outflow tract obstruction can occur at the supravalvular, valvular, or subvalvular level. Each level of obstruction is associated with distinct symptomatology, natural history, and operative approach. We describe a case of asymptomatic double site of left ventricular outflow tract obstruction: subvalvular aortic stenosis associated with valvular aortic stenosis.
