I am sitting here 1 week post op from my 3rd surgery. From my previous 2 I was under the impression that the risk were significantly higher. I live in a city with a fantastic health system and top rate surgeons. I am very active and healthy 41 year old. I had resided that I would need to put in a mechanical valve when the 2nd tissue failed. After my cardiac cath pre op procedure both my cardiologist and surgeon started to talk to about considering a TAVR. This excited me because I would really hate to miss out on new valve options that COULD be coming that last and don't require warfarin. The day before the procedure my surgeon changed his mind based on 2nd echo he had me undergo. I am glad he did because it turned out that my previous valve had started to fall apart and a TAVR could have given me a stroke in this instance. So from there I really dug in on true risk of the surgery for me at my health and age. I considered what the future might offer. This included considering taking warfarin as I see new long lasting valves not requiring warfarin are put into new patients. I thought about getting another tissue valve that has has good historical data to last longer than my previous 2 (I have had some bad luck there) and then possibly getting a TAVR for the 4th. In the long run these decisions are incredibly hard/personal. I went with the tissue valve and told myself I need to keep in shape to prepare for the next time around. At 26, 34 and 41 I have time and time again decided to bet with science and deal with the recovery vs. the warfarin. That my choice.
My recommendation for you is to get the data from your doctors. What they say the risks are for you. In the end that's what will guide you to your decision.
