High reoperation rates after resection for subaortic stenosis warrant caution; leaves open optimal surgical strategy in children.
Observational (n=45)
What are the long-term outcomes and reoperation rates following surgical correction of fixed subaortic stenosis?
Surgical correction of subvalvar aortic stenosis carries a significant risk of recurrent stenosis requiring reoperation even up to 17 years post-procedure.
Stewart et al. (1990) conducted an observational in fixed subaortic stenosis (n=45). Surgical correction (local resection, myectomy, or aortoventriculoplasty) was evaluated on Reoperation for recurrent obstruction. Surgical correction of subvalvar aortic stenosis was followed by recurrent stenosis necessitating reoperation in 27% of patients over an average follow-up of 47 months.
