Itís very hard to put into words the experience of being told you have a life-threatening medical problem. Many of you reading this know that first hand. There is a flood of different feelings all at the same time. If you are like me, and didnít even feel sick, the shock of it seems all the more difficult. One day Iím running a half marathon and two months later Iím diagnosed with severe aortic stenosis. Thus began the process of figuring out what to do and when to have it done. Initially I was told I would have several years before I would require valve replacement. Over the next few months it became clear that was not the case. My aortic aneurysm was large, my bicuspid aortic valve was stenosed and I wanted to remain active. The surgeons I spoke with said 3-6 months without exception.
When I first started researching the treatment options of valvular heart disease, I donít think I had quite accepted my fate. Basically I wanted a solution that would allow me to go on just as I had before I knew the condition of my valve. Unfortunately, that solution doesnít exist. Donít get me wrong, I was very happy there was a fix for my bicuspid aortic valve and aortic aneurysm but the fix was open heart surgery. That was scary.
I found out there are currently three different options for treating bicuspid aortic valve in adults 1) mechanical heart valve, 2) tissue valve, 3) Ross procedure. I was initially interested in the Ross procedure, a surgery in which the patientís existing pulmonary valve is used as the replacement for the diseased aortic valve. A tissue valve (usually human cadaver valve) is then used to replace the pulmonary valve. I thought this could be the ideal solution for me because I could avoid medication and in theory, have a life-long solution that would not require re-operation in the future. After meeting with a surgeon who recommended the Ross procedure and doing a more thorough literature search, I met with surgeons here in San Diego and in Los Angeles. Armed with a more thorough understanding of the Ross procedure, I decided I was not a good candidate for that procedure. There remained too many questions about the need for further operations on one or both valves in the future. If I had followed the first surgeonís recommendations without researching the details more carefully, I would have undergone the Ross Procedure based upon my desire for the ďideal solution.Ē After ruling out the Ross procedure, I then moved on to the decision between the more traditional treatments with a mechanical heart valve or tissue valve.
It was an interesting process, deciding between a tissue and mechanical heart valve. Initially, in my quest to get my same life back, I thought tissue would be the way to go but after speaking to several surgeons my mind began to open up to the possibility of a mechanical heart valve. There are some general guidelines for surgeons as to which type of valve should be used for replacement of the aortic valve.
Even with that information I still wasnít sure I wanted to take warfarin all my life. There is so much negative information on warfarin that I really wanted to educate myself on the risks of warfarin vs. another operation in 8-12 years. These conclusions are what helped me decide:
Now having gone through open heart surgery Iím amazed at how good I feel but I would not want to plan on doing it again. In the end there are many things to consider in making this decision. I am glad I talked with several doctors who urged me to look at all the possibilities because initially I really couldnít picture myself taking warfarin for the rest of my life. I am very happy with my valve and I know this is the best choice for me. You may decide a tissue valve is a better choice for your life. But whatever you decide, I hope you find this information useful.
* Please note: The mortality risk of redo aortic valve replacement is somewhat lower than the risk of a redo aortic root replacement. The exact number varies significantly with the hospital, surgeon, and other factors, including the patient's underlying health problems.
