Discrete subaortic stenosis (DSS) is considered an acquired lesion caused by a progressively enlarging shelf of fibrous or fibromuscular tissue beneath the aortic valve. We present a case of DSS caused by a flap of tissue attached to the aortic valve cusp. A pathological analysis of the resected flap suggested that it was valvular tissue, thus supporting the diagnosis of DSS secondary to congenital accessory aortic valve disease.

Key words: discrete subaortic stenosis; aortic valve; aortic valve stenosis; VACTERL association; aortic valve insufficiency
