Ten years ago, my tennis partner suffered a stroke. He was a sixty-year-old at the time, working to move up into the top ten players in his age group. In the country!

For most of us however, the first time we took a breath of air after being born, our foramen ovales began to close, the two sides of the wall separating the atria eventually fusing. But in the case of my tennis partner, that FO remained a PFO. He lived for sixty years unaware that there was a hole still open between the two sides of his heart.
