Abstract
Fifty elderly patients who had suffered cerebrovascular incidents from no obvious cause and 33 age-matched controls were investigated for the presence of a patent foramen ovale by contrast 2-dimensional echocardiography at rest and after the Valsalva manoeuvre. Right-to-left shunting was found in only one patient and in none of the controls. This finding is in contradistinction to young adult stroke patients in whom the prevalence of a haemodynamically significant patent foramina ovale is high. Paradoxical embolism is an uncommon cause of stroke in the elderly.
