Supports aggressive resection in discrete subaortic stenosis; extends observational data but leaves open need for randomized confirmation of durability and risks.
Does an aggressive surgical resection of discrete subaortic membrane improve aortic regurgitation and LVOT gradient in patients with discrete subaortic stenosis?
An aggressive surgical approach to discrete subaortic stenosis effectively relieves LVOT obstruction and reduces associated aortic regurgitation with benefits maintained at mid-term follow-up, though with a risk of heart block in reoperations.
Parry et al. (1999) studied this question.
