Strokes and holes in the heart - a solid explanation

A good explanation of what likely happened to me almost 20 years ago - a hole in the heart causing a stroke. A trusty Google alert found this good, simple explanation how after a stroke with no clear cause, a heart repair may be in order:

Most strokes occur when a clot blocks blood flow to part of the brain. Often, doctors can tell what caused the clot to form. But about a quarter of the time — especially in people younger than 60 — there is no obvious reason. These types of strokes are known as cryptogenic (meaning "of hidden origin").
One possible cause underlying a cryptogenic stroke is an opening in the wall that separates the heart's right and left upper chambers (atria). Known as a patent foramen ovale, or PFO, this flaplike opening is quite common. About one-quarter of all adults have a PFO (see "What is a patent foramen ovale?").
"But about 45% of people who have cryptogenic strokes have a PFO, which suggests the two conditions are related," says Dr. John Jarcho, a cardiologist at Harvard-affiliated Brigham and Women's Hospital. Yet for years, the question of whether closing a PFO could prevent additional strokes has been hard to answer.
