The operation for HOCM is called septal myectomy. Septal myectomy is performed in patients who have symptoms despite medical therapy, or if the obstruction severely restricts blood ejection from the heart. Patients often experience rapid relief of symptoms after the procedure, and the effects are long-lasting.
A septal myectomy is an open-heart procedure in which the surgeon removes part of the thickened, overgrown septum between the ventricles. Removing part of this thick muscle improves blood flow and reduces mitral regurgitation.
Septal myectomy is the procedure of choice for treating hypertrophic cardiomyopathy (HCM). However, it involves the risk of incomplete resection of septal muscles or iatrogenic septal perforation depending on the surgeon’s practice. Herein, we suggest a few tips for successful septal myectomy and present a relevant case.
