Why the study?
Does excision of the subaortic membrane with resection of septal muscle improve outcomes compared to excision alone in patients with discrete subaortic stenosis?
Population
40 patients with discrete subaortic stenosis operated on between 1978 and 1990
Comparison
Excision of the subaortic membrane with… vs Excision of the subaortic membrane alone

Both approaches show equivalent safety and gradients; leaves open whether myectomy reduces long-term recurrence.
Does excision of the subaortic membrane with resection of septal muscle improve outcomes compared to excision alone in patients with discrete subaortic stenosis?
Both excision of the subaortic membrane alone and with septal myectomy resulted in no operative or late deaths and similar transvalvar gradients, though long-term follow-up is needed to assess recurrence.
Lupinetti et al. (1992) studied this question.
