DR D. CRAIG MILLER (Stanford, CA): Doctor Jamieson was kind enough to share his data with me in advance, and I would like to underscore to the audience that this is the first porcine valve paper really getting out toward 20 years of follow-up with large patient samples. In the past we have only had the Starr-Edwards ball valve to talk about 20-year survival. I think this is noteworthy. There are a couple of sobering facts here, however, which deserve emphasis, even though all of us should already be aware of them.
Number one, very few patients are alive 20 years after valve replacement. We do not need, in general, a valve that is going to last for 50 to 100 years. Number two, the overall incidence of valve-related complications remains very high, but I would like those of you who read the article to focus on the valve-related mortality data; I submit there has never been a valve over 18 years associated with such relatively favorable, albeit still imperfect, freedom from valve-related mortality rates. However, as I said last year at this meeting discussing Ellis Jones' paper from Emory, all of these actuarial curves are misleading and fallacious. They are over-estimates of anything bad that can possibly happen because they are population-derived curves, which impute that everyone is going to live forever, which certainly is not the . . .
