Patent foramen ovale is associated with stroke. However, the rate of recurrent events in medically treated patients with patent foramen ovale remains undefined. Estimates differ by the studies. In order to provide a more accurate estimate of the recurrent adverse event rates in medically treated patients with patent foramen ovale, we reviewed the literature and analyzed the results from a total of 1,108 patients combining 12 studies. We found the annual rate of stroke or death to be 3.12% (95% CI, 2.32-4.11%). This estimate will provide a valuable guideline for any future study to compare the efficacy of other modalities such as percutaneous device closure of patent foramen ovale with medical treatment.
