Surgery for hypertrophic cardiomyopathy is aimed at eliminating the thickening of the interventricular septum, which obstructs blood flow from the left ventricle. During the procedure, the surgeon carefully resects the excess muscle tissue, widening the left ventricular outflow tract and restoring normal blood flow. As a result, you will get rid of debilitating shortness of breath, pressing chest pain, and sudden fainting episodes, and the risk of fatal arrhythmias decreases tenfold. You are no longer dependent on intensive drug therapy and can return to an active life without the constant fear of heart-related events.
