I had a dry persistent cough that was slowly getting worse. That was fixed with the 12 platinum coils to block the bronchial artery to pulmonary artery fistula. Both this fistula and complex coronary fistula are rare. I had angina sharp pains on the left side when I was sitting at my desk, on the end of the couch and my recliner. The heart sounded normal via stethoscope. I had swelling in both ankles and face. I was getting extremely fatigued and it was getting progressively worse. I was showing signs of congestive heart failure. The cardiac MRI (at Mayo) showed my heart to be in good shape with no damage which was excellent news going into open heart surgery. The complex fistula probably accelerated the occlusion of the LAD but ironically, collaterals from it were keeping me alive until it started killing. It seems I had a couple of rare congenital problems that I was born with and not found until I as 60 along with a genetic problem and a weird synergism with age related LAD calcification.

Edit: I will add that I was disappointed on Aug 6th when the angiogram with possible intervention couldn't fix the complex fistula with coils and stents to fix the LAD, but as it turned out, it was for the best in the long run due to the complexity and the fact that while the measurement of the root made surgery discretional, it was fragile which the CT, Echo, MRI, and Angiogram couldn't determine.
