Surgery is scary. My husband had an aortic valve replacement
3 years ago, and it's done it's job well. Make sure though, to research and discuss at length with your doctor, surgeon, etc. whether to choose a tissue valve or mechanical valve. There are both advantages and disadvantages to either, and you have to determine which one is right for you. The recovery process can take about 6-12 weeks, but if you're healthy otherwise, you should be literally good as new.
