The medical examiner spoke slowly, explaining the results of the autopsy on the young man who died suddenly. The heart weighed 860 g, so there is really no question, the young man’s death was from hypertrophic cardiomyopathy, he explained. “Everything else was fine. It is a relief to get a clear cause of death, we do not always get one in these cases.” There was a gentle tone to his voice when he spoke to me, no doubt because the young man he was describing was my son.
