title: Subaortic stenosis: recurrence of a fibrous ring after 28 years.
abstract: Aortic stenosis is a common cardiac problem. Morphological aortic stenosis can be due to valvular, subvalvular and supravalvular causes. Subvalvular causes include subaortic rings and membranes, which usually manifest at a young age, depending on the size of the ring and the degree of obstruction. Recurrent (post-operative) stenosis is a rare potential problem. A case of recurrent subaortic stenosis due to a subaortic ring, 28 years after the initial surgical excision of the ring is presented.
