Septal Myectomy (Morrow)

Surgical septal myectomy is commonly used for obstructive hypertrophic cardiomyopathy and can be performed if the anatomical conditions are suitable, with mitral valve apparatus repair if necessary. Usually, under general anesthesia and cardiopulmonary bypass support, the thickened septal muscle bundles are resected via a cardiac approach to expand the left ventricular outflow tract. Intraoperative transesophageal ultrasound and monitoring are used to assess patency and valve function. Postoperatively, hemodynamic and cardiac rhythm are observed in the intensive care unit, with the goal of relieving obstruction, improving symptoms, and exercise tolerance. The above is general health information and not medical advice; specific information is subject to specialist assessment and hospital protocols.
