Ski Girl came up with an interesting name for the mechanical valves that many of have had implanted in our chests. She called hers a 'ticking time bomb.'
I've had mine (St. Jude) since 1991. I've gotten to where I don't really hear it -- and my wife doesn't seem to be hearing it, either. My daughter visited this weekend and SHE was able to hear it very clearly -- she even told me when to take a break, based on my heart rate. It was rather surprising to learn that SOME people can still hear this thing.
SO -- I know it ticks - and even if it may not be as loud as when I first got it, some people can still hear it.
Now - to the time bomb thing:
I guess that, in principle, these things really CAN BE thought of as time bombs -- but they aren't really designed for spectacular failures like some devices may be. From what I recall, the expected life for the St. Jude is about 40 years or so.
So, here's my question -- do these valves give any warning of impending failure? Aside from occasional echocardiograms (or other testing), is it possible to predict a valve's failure so that something can be done proactively? I know that work's still being done to do repairs without cracking the chest open - and it may be good to know that 30 years from now, such a repair will be an in office or outpatient procedure -- but until then, do we look at these things as ticking time bombs?
