Abstract

The prevalence of patent foramen ovale in patients presenting with non-haemorrhagic stroke or transient ischaemic attacks under the age of 40 years was determined by contrast echocardiography. Studies were performed at rest and with a Valsalva manoeuvre in 40 stroke patients and in an age and sex matched control group. Right-to-left shunting was found in 20 (50%) of the stroke patients and 6 (15%) of the controls (p less than 0.001). Paradoxical embolism through a patent foramen ovale may be an under-recognised cause of stroke in young adults.
