Septal myectomy, surgical implantation and heart transplant are surgeries used to treat cardiomyopathy, notes the National Heart, Lung and Blood Institute. Doctors determine whether patients need surgery to treat cardiomyopathy based on symptoms, overall health, age and underlying complications.
Septal myectomy is open heart surgery during which surgeons remove part of the septum that is bulging into the left ventricle of the heart, states the National Heart, Lung and Blood Institute. Surgeons may also choose to repair or replace the mitral valve during a septal myectomy. Left ventricular assist devices and implantable cardioverter defibrillators are two of the devices surgeons may choose to implant in order to control cardiomyopathy. For people with end-stage heart failure, doctors may choose to conduct a heart transplant.
