When I was asked to give the “Founder's Lecture” at this summer's meeting of the Society for Cardiovascular Angiography and Interventions (SCAI), they asked me to speak on “The Birth and Evolution of Coronary Interventions.” It occurred to me that everything I could say was not only in the past, but the actual lecture was also in the past, since I had given the first Founder's Lecture at SCAI in 1989. Only this time, I had another 33 years of history to relate. If I had had access to those 33 years in 1989, I could have given a really interesting lecture because the past is what we know but the future is what we want to know.
