I think we all agree that the type of valve is best decided on in consultation with your surgeon. You have a choice between animal tissue and mechanical because of your age. My surgeon explained that my only option was animal tissue since I'm 71 (apparently the limit for mechanical is 70). The downside of animal tissue is that it only carries and "unwritten" warranty of 10-15 years and maybe I'll die of something else before I face another open heart procedure; however I've vowed to get an extension to my warranty with good clean living and all those healthy habits (e.g., lots of exercise) that we should have been doing all along. Whatever your choice, best wishes to you.
