I was 48 when diagnosed with a number of blockages. I never had a heart attack. I was experiencing angina when walking or running up an incline. I underwent an angiogram and it was determined that the blockages were too extensive for stenting. My ECG was normal. I underwent on-pump bypass. The surgeon was quite skilled (reputation) and the surgery entailed bilateral internal thoracic artery (insitu) graft surgery to the left anterior descending and posterior circumflex, plus a vein graft from my leg to the RCA and 2 diagonal grafts. Following surgery, my in hospital stay was 8 days (longer than expected). I also had 3 blood transfusions due to blood loss during the surgery. I was on pump for 176 minutes. A post surgical ECG found RBBB. I understand what this is and that there is no "cure". So, is this a common outcome of by-pass surgery? The branch must have been stretched during the surgery.
