    AbstractTo observe the association between migraine and patent foramen ovale (PFO) using contrast-enhanced transthoracic echocardiography (cTTE). Eighty-five migraine with aura (MA) patients and 85 migraine without aura (MO) patients from January 2020 to February 2022 were divided into group A and group B, respectively. Sixty-five healthy people were included in normal control group. Difference of PFO positive rate among group A, group B, and normal control group was significant (p=0.002). Difference of PFO related right-to-left shunt (PFO-RLS), Grade 2 shunt, and Grade 3 shunt among group A, group B, and normal control group was significant (p=0.043 and p=0.013 respectively). PFO-RLS Grade 2 and 3 shunts may play an important role in MA patients and MO patients, and the size of PFO-RLS shunt may be associated with migraine. Key Words: Migraine, Patent foramen ovale (PFO), Right-to-left shunt (RLS), Contrast-enhanced transthoracic echocardiography (cTTE).
