Key result
Follow-up of 65 patients with discrete subaortic stenosis showed development of aortic regurgitation and progressive membrane growth in both surgically resected and non-operated cases.
Why the study?
Does surgical resection of the membrane alter the evolutive aspects of discrete subaortic stenosis in children compared to no surgery?
Population
65 children with discrete subaortic stenosis (DSS)
Comparison
Surgical resection of the membrane (n=28) vs No surgery (n=37)

DSS may warrant serial monitoring in children; leaves open whether resection modifies aortic regurgitation risk.

Does surgical resection of the membrane alter the evolutive aspects of discrete subaortic stenosis in children compared to no surgery?
Discrete subaortic stenosis has an evolutive character with progressive membrane growth and development of aortic regurgitation regardless of surgical resection, requiring long-term observation.
Firpo et al. (1990) conducted a cohort in Discrete subaortic stenosis (DSS) (n=65). Surgical resection of the membrane vs. No surgery was evaluated on Development of aortic regurgitation and progressive growth of the membrane. Follow-up of 65 patients with discrete subaortic stenosis showed development of aortic regurgitation and progressive membrane growth in both surgically resected and non-operated cases.
