A Case of Successful Valve Repair for Aortic Insufficiency Associated with Discrete Subaortic Stenosis

Discrete subaortic stenosis (DSS) is an uncommon form of left ventricular outflow tract obstruction especially in adulthood. Moreover, aortic regurgitation (AR), which is a common sequence of DSS, requiring surgical correction is extremely rare. We report the case of a 33-year old man who had severe DSS accompanied with moderate aortic insufficiency. He underwent successful surgery including relief of DSS and aortic valve repair. Although careful follow-up is mandatory for recurrent AR and DSS, our approach was thought to be feasible for a young adult patient with DSS complicated with AR.
