INTRODUCTION: Screening for patent foramen ovale (PFO) in patients with ischemic neurological events is becoming more common.
OBJECTIVES: This study aimed to evaluate clinical characteristics and atrial septum anatomy in relation to age and presence of PFO, as well as factors associated with a history of stroke in patients assessed for cardiac causes of ischemic neurological events.
PATIENTS AND METHODS: A total of 817 patients with a history of neurological episodes (stroke, transient ischemic attack [TIA], or migraine) were prescreened using transcranial Doppler ultrasound. Transesophageal contrast echocardiography (TEE) was employed to confirm PFO and assess the anatomy of the atrial septum and right atrium.
RESULTS: Among the patients, 28% had ischemic stroke, 31% had TIA, and 49% had migraines. PFO was confirmed in 79% of the patients. Regardless of the analyzed age group, PFO was associated with higher prevalence of TIA, migraine and syncope history, atrial septal aneurysm (ASA), and Chiari network. There were fewer women in the PFO group, but only in the population aged 45 years or under. Patient age, male sex, typical cardiovascular risk factors, and the presence of ASA were associated with a history of stroke.
CONCLUSIONS: In patients with ischemic neurological events who were prescreened for PFO, confirmation of PFO on TEE was associated with a higher prevalence of TIA, migraine, syncope, Chiari network, and ASA. Advanced age, typical cardiovascular risk factors, and ASA were associated with stroke history in the study population.
