I know few will agree with me, but I would not submit to something as invasive as OHS for a valve replacement if I were not having symptoms. I say this for several reasons. A few months ago after my annual Echo my interventional cardiologist told me that my aortic valve regurgitation had progressed from moderate to severe. I was quick to protest that assessment given the fact that I felt great, ran 4-5 miles every other day, and lifted weights heavily twice a week. I also provided him with documentation showing that over the 13 years since my MV replacement the aortic valve regurgitation had jumped around, back and forth, between mild and moderate, and now severe. Consequently, as I told him, I did not put much stock in this new diagnosis. My supposed fluctuating ejection fraction percentage is another story, although he admitted that determining the EF from an Echo is a rough estimate depending on the quality of the sonogram. He similarly acknowledged that the expertise, or lack thereof, of the cardiac sonographers could account for his inability to make a perfect diagnosis of valve regurgitation severity. S, we agreed that I would have a TEE to get a better look at my AV regurgitation. As you might guess by now, it showed my AV regurgitation as being moderate and not severe. It scares me to think that OHS is often performed on asymptomatic patients based on the results of a dubious Echo. Incidentally, my feelings about this have also been impacted by my experience with my electrophysiology "experts". I have had second degree heart block, Mobitz type 2, since my MV replacement and since then my HR drops to 30 bpm during the night, every night, consistently, with no ill effects or symptoms. Depending on which cardiologists, PA, or NP I speak to, I either need a pace maker immediately, or, I don't need one at all. I am going with the latter as long as my HR responds during exercise. I have never fainted and I don't have dizzy spells. I've decided that there are two kind of patients. Those who blindly do everything a doctor tells them to do, and those who take responsibility for their own health and quality of life.
