Patent foramen ovale
Introduction: Patent foramen ovale
A defect (incomplete closure) in the wall between the two upper chambers of the heart. The defect is a normal occurrence before birth but the opening eventually closes over in about 80% of people. Straining caused by sneezing or coughing can cause the defect to push open and allow blood to flow between the two chambers. This means that the blood doesn't pass through the lungs where any waste such as clots are removed. This contaminated blood can result in clots traveling to other parts of the body where they can become lodged and cause conditions such as strokes. Also called PFO.
