Surgical valvotomy for critical aortic stenosis in infants resulted in an overall mortality of 15%, with no deaths among the 16 infants treated since 1979.
Cohort (n=20)
What are the mortality and re-operation rates following surgical aortic valvotomy for critical aortic stenosis in neonates and infants?
Surgical valvotomy for critical aortic stenosis in infants achieved excellent survival in the modern era (post-1979), serving as an important benchmark for evaluating balloon dilatation.
Between April 1974 and December 1987, 20 infants (six under one month of age) (mean weight 4.9 kg) underwent surgical valvotomy for critical aortic stenosis. Three of the four patients treated before 1976 died. Since 1979, 16 infants (four neonates) have undergone valvotomy with no deaths. Mortality for the whole group was 15%; in the neonates it was 33%. There were no late deaths. The survivors were followed up for a mean of 3 years 9 months and two required re-operations. The considerable improvement in surgical results in the past decade should be taken into account when newer techniques such as balloon dilatation are evaluated.
Balaji et al. (Sat,) conducted a cohort in critical aortic stenosis (n=20). Surgical valvotomy was evaluated on Mortality. Surgical valvotomy for critical aortic stenosis in infants resulted in an overall mortality of 15%, with no deaths among the 16 infants treated since 1979.
