Septal myectomy is a cardiac surgery treatment for hypertrophic cardiomyopathy (HCM). The surgery entails removing a portion of the septum that is obstructing the flow of blood from the left ventricle to the aorta. Septal myectomies have been successfully performed for more than 25 years. The alternatives to septal myectomies are treatment with medication (usually beta or calcium blockers) or non-surgical removal of tissue with alcohol ablation. Ordinarily, septal myectomies are performed only after attempts at treatment with medication fail. The choice between septal myectomy and alcohol ablation is a complex medical decision. ==Outcomes== Septal myectomy is associated with a low perioperative mortality and a high late survival rate. A study at the Mayo Clinic found surgical myectomy performed to relieve outflow obstruction and severe symptoms in HCM was associated with long-term survival equivalent to that of the general population, and superior to obstructive HCM without operation.
