Brief Summary

Migraine is a common, chronic neurovascular disorder characterized by attacks of severe headache, autonomic nervous system dysfunction and, in some patients, aura, and disabling neurological symptoms. Worldwide, migraine prevalence is as high as 18% in the general population. Increased frequency of patent foramen ovale (PFO) in migraineurs was first reported in 1998 in a case-control study. Since then, others have described a 60% prevalence of PFO in patients suffering from migraine with aura. The presence of a right-to-left shunt (RLS) is thought to be a potent trigger of migraine attacks, although the mechanism is unknown. Moreover, PFO closure has correlated with improved migraine symptoms in several retrospective uncontrolled studies. The aim of this single-center, prospective study is to assess the impact of PFO closure on migraine attacks over time together with evaluation of potential predictive risk factors.

Outcome Measures

Primary Outcomes (2)

  • Change in Migraine Characteristics

    The evaluation in absolute numbers of patients fully responders, non-responders or with a moderate benefit on migraine symptoms after PFO Closure was performed

    The outcome data were evaluated at 6-months and 12-months after PFO closure and compared to baseline

  • Migraine Assessment by Anzola's Score

    The change in migraine severity, incidence and duration with or without aura as measured by the Anzola's score (The score is the expression of the sum of each corresponding value referring to migraine duration, frequency and the presence or absence of aura). The minimum value was 2 and the maximum 9; the higher the value, worse is the migraine classification. Anzola's score: Duration 0=No pain 1=\<6 hours 2=6-12 hours 3=\>12 hours Frequency 0=No pain 1=1-4/month 2=5-9/month 3=\>10/month Aura 0=No aura 1=Aura in ≥1 attack

    Baseline, 6 months and 12-months after PFO closure

Secondary Outcomes (6)

  • Platelet Activation (I)

    baseline and 6 months after PFO closure

  • Platelet Activation (II)

    Baseline and 6 months after PFO closure

  • Platelet Activation (III)

    baseline and six months after PFO closure

  • Platelet Activation (IV)

    Baseline and six-months after PFO closure

  • Platelet Aggregation (I)

    baseline and 6 months after PFO Closure

  • +1 more secondary outcomes

Study Arms (2)

Migraine evaluation in PFO patients

EXPERIMENTAL

Patients symptomatic for migraine with/o aura and addressed to patent foramen ovale closure (Occlutech Figulla Flex II PFO occluder device) for a previous ischemic event, will receive dual antiplatelet therapy (DAPT) for 2 months after procedure and aspirin alone subsequently. Patients will undergo evaluation of platelet reactivity, serotonin and cytokines before PFO closure with a dedicated device and at 6 months follow-up and these results compared to those of a control, group of healthy subjects treated with aspirin alone

Device: patent foramen ovale closure

healthy subjects on aspirin treatment

NO INTERVENTION

12 healthy subjects on 100 mg aspirin daily will be compared to PFO patients in terms of platelet reactivity, serotonin and cytokines

Interventions

Pts undergoing PFO closure will receive 2-months of DAPT and 6 months of aspirin after patent foramen ovale (PFO) closure; they will be compared to healthy subjects on aspirin treatment

Also known as: Occlutech Figulla Flex II PFO device; aspirin

Limitations and Caveats

MHA may have a multifactorial etiology. The role of oxidative stress appears consistent and corroborated by the in vitro data. The effect of serotonin and oxidative stress was tested on platelets from healthy subjects and not from pts because the Sars-Cov-2 pandemic imposed restrictions on pts enrolment. Finally, the thrombin generation capacity of platelets and MVs were included after the study started to support the pro-coagulant phenotype evidenced by ad interim flow cytometry data analysis
