Subaortic Membrane Resection with Septal Myectomy or Septal Myotomy -A Surgical Dilemma
Journal Title: PARIPEX-Indian Journal of Research - Year 2016, Vol 5, Issue 10
Abstract
Subaortic membrane (SAM) is a fixed subaortic obstruction in which a fibrous membrane is located below the aortic valve. It ranges from discrete subaortic stenosis to a severe form of Shone complex. Affected patients face an increased risk of bacterial endocarditis and of Aortic Insufficiency (AI) when fibrous strands extend into the base of aortic leaflets. The development of left ventricular hypertrophy (LVH) or aortic insufficiency (AI) is a clear indication for operation. The timing of intervention in the asymptomatic patient is controversial. Surgical treatment involves the resection of the fibromuscular subaortic membrane with or without septal myotomy or myectomy. Despite excellent early results, the recurrence rates for subaortic stenosis have been disappointing. Hence a retrospective study was conducted for the superiority of the subaortic membrane resection with septal myectomy and myotomy. But, similar results are seen with both the methods with no complications and low recurrence rate.
