 “…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?’”
