“…About 6 months earlier this patient had had a porcine graft in the aortis annulus in a city in Lousiana. The poor bewildered mother, knowing that her son had received a pork graft, asked me what type of valve we would now use. I told her we would use a Bjork Valve. She said, ‘what kind of animal is a Bjork?’”
