What does Surgical Septal Myectomy involve?

Surgical Septal Myectomy is an open-heart procedure performed under general anesthesia. The surgeon makes an incision through the sternum (median sternotomy) to access the heart, then removes a small portion of the thickened septal muscle that obstructs blood flow from the left ventricle. This relieves the outflow tract obstruction caused by hypertrophic obstructive cardiomyopathy (HOCM), improving cardiac function and symptoms like shortness of breath and chest pain.
