In the springtime of 2011 under emergency conditions at age 58, I had the On-X Aortic Heart Valve, size 21mm, installed. I couldn’t have picked a better surgeon or state of the art prosthetic heart valve even if I had time to study, shop and compare. I had my valve installed on a Tuesday morning,…

I have been a devoted distance runner and cyclist since my college days. At age 57, I began experiencing increasing levels of exercise intolerance, which prompted me to see my doctor in June 2010. I was diagnosed with atrial fibrillation and moderate aortic stenosis resulting from a heavily calcified bi-cuspid aortic valve. This came as…
