Stroke as a complication of congenital heart disease
Patent foramen ovale is a common finding in the general population. It is associated with an increased risk of stroke, but it may not have a significant effect on recurrent stroke risk in medically treated patients. Recently, many questions have arisen with respect to best treatment for preventing recurrent stroke. Some data from a clinical trial of anticoagulation compared with antiplatelet therapy support anti-platelet treatment for secondary prevention. There are not enough data currently to support surgical or percutaneous closure of patent foramen ovale for stroke prevention.
