A patient who received a double heart valve replacement at the University of Alabama in Birmingham on Oct. 2, 1990, was recently named the Guinness World Record holder for the longest survivor of the procedure. Seth Wharton, 44, of LaVale, Md., received the transplant when he was 13, according to an April 18 press release. His heart problems began when he was four days old after physicians discovered he had an enlarged heart. He has had three open-heart surgeries and six cardiac catheterizations in addition to the double valve replacement.
