Patients who underwent both bubble transcranial Doppler (bubble-TCD) and transoesophageal echocardiography (TEE) at our institution were consecutively enrolled in this real-world case-control study from August 2016 through August 2023. The patients were categorized into three groups based on the degree of the shunt observed: mild (3-9 bubbles), moderate (10-30bubbles), and severe (more than 30 bubbles). In cases with mild-shunt (small-size) PFO, post-procedural anticoagulation or PFO closure was administered. Subsequent to the interventions, the follow-up encompassed the recording of migraine remission, recurrent neurological incidents, instances of major bleeding, and mortality.
