I have HCM and recently had a myectomy surgery. I had complications including heart block requiring a pacemaker /defibrilator and VSD (ventricular septal defect) which is a hole in the septum. It is moderate in size and will most likely need repaired. I have already gone into heart failure and am on lasix and low sodium diet. I am unsure how to proceed as my surgeon seems reluctant to do anything and my cardiologist says it needs fixed.
