Abstract

Background: Cryptogenic stroke, whose underlying pathology is unknown, accounts for 30-40% of all ischemic strokes. Studies have mentioned the association between atrial septal abnormalities and cryptogenic stroke, but there are still disparities in the results among different studies.

Objective: We aimed to clarify the prevalence of atrial septal abnormalities in patients with cryptogenic stroke.

Methods: We conducted a cross-sectional study on 91 patients with cryptogenic stroke/transient ischemic attack from March 2021 to March 2022. We evaluated the demographic data of the patients and also the existence of neurologic attacks. Furthermore, echocardiography was performed to determine the type of atrial septal abnormality.

Results: Out of 91 patients with cryptogenic stroke/transient ischemic attack, 16 patients (17.5%) had patent foramen ovale, 1 man (1.1%) had atrial septal aneurysm, and 1 woman (1.1%) had an atrial septal defect. Patients with patent foramen ovale were significantly younger than those without. The size of patent foramen ovale in patients with cryptogenic stroke was larger than those with transient ischemic attack, but this difference was not significant. Also, the size of the patent foramen ovale (length and width) was not significantly related to any of the demographic variables (p-value = 0.544, 0.604).

Conclusion: Based on our results, the prevalence of atrial septal abnormalities was relatively high. Considering these issues and the importance of preventing neurological accidents in patients, especially young people, it is recommended to always consider atrial septal disorders and, if diagnosed, to carry out the necessary treatment in this field.
