PFO: Sometimes is the best answer that i can give now. If there is significant flow across the pfo then it should be closed, or if there has been evidence that blood clots have crossed the opening then it should be closed. This can be done at a specialized center with a catheter based procedure.

Asd yes pfo maybe: Significantly large (meaning that the right heart is enlarged) ASD needs to be closed. Pfo is noted in up to 20 % of the population. It has no relevance. There may be (data is weak) an association of pfo with stroke. Currently the american society of neurology recommends closure only after first recurrence of a stroke. Very controversial topic.
