Why the study?
Does surgery compared to medical follow-up improve echocardiographic left ventricular outflow gradient and aortic insufficiency in children with discrete subaortic stenosis?

Children with mild subaortic stenosis show little progression and can be managed medically, while those with severe stenosis progress rapidly and benefit from early resection despite surgical risks.
No takes yet. Share an insight, caveat, or question.
May support medical surveillance for mild discrete subaortic stenosis; leaves open optimal surgical timing in moderate cases.
Rohlicek et al. (1999) studied this question.
