Does Atrial Septal Anatomy Still Matter in the Etiological Evaluation of Ischemic Stroke Beyond the Age of 60?

PFO presence remains strongly associated with cryptogenic stroke between 60 and 80 years of age. Large PFO, ASA, and their association were strongly associated with cryptogenic stroke in this age group. Our results support performing contrast echocardiography even after 60 years of age, although the optimal secondary prevention therapy in this population remains to be determined in randomized trials.
