Abstract
Case histories of 50 consecutive infants and children with congenital valvular aortic stenosis treated at the Montreal Children''s Hospital, Canada, during the past 16 yr were reviewed to determine the efficacy of the initial treatment and the long-term results. The operative technique employed was to incise fused commissures out almost to the annulus without causing aortic insufficiency, but often the accomplishment was limited by valve anatomy or cusp dysplasia. Of the 7 operative deaths 6 occurred in infants. Eight to 16 year follow-up on the first 25 survivors revealed 1 late death, 4 good results, 5 aortic valve replacements and 3 second valvotomies. Ten patients have recurrent aortic stenosis and 2 have moderate aortic insufficiency. Aortic valvotomy is a palliative operation, and .apprx. 1/3 of the children operated upon will require a 2nd operation within 10 years.
