OK so this is my first post. I am a 47 year old male. I had always known that I had a heart murmur, even as a young child. I was diagnosed with aortic stenosis in 2001. At that time the valve was at 1.5cm. It held there until the past few years, Two years ago 1.3cm. Now the valve opening is down to 1.0cm. Gradient resting is 36 and peak is 63. I have no symptoms other than fatigue is much more noticable. Light to moderate exercise is helping however an exercise program has never been more difficult to start. I have a high stress job in management. I know that I am realistically within 2-3 years of surgery. I dislike the fatigue and restrictions and am asking those that have had surgery what I can expect on the other side. What are the affects of the blood thinner medicine should I go mechanical? Should I plan a change in lifestyle? As time grows nearer the anxiety grows! Thanks for any imput you may have.
