Since the early 1960s, surgical septal reduction, also known as septal myectomy, has been used as a therapy for the treatment of obstructive hypertrophic cardiomyopathy. Pioneered at the National Institute of Health by cardiac surgeon Dr. Glenn Morrow, himself a HCM patient, septal myectomy has become a mainstay of the HCM treatment arsenal.
For many years, the indications for ASA procedures has been limited to older patients with obstructive HCM who were not otherwise healthy enough to undergo open heart surgery. However, some doctors are now advocating to expand the indications for ASA to include symptomatic younger patients.
