Authors' conclusion

This study confirms the long-term efficacy and safety of transcatheter PFO closure for patients with cryptogenic embolism and PFO in a real-world setting.

Study context

Population
Patients who underwent transcatheter PFO closure for cryptogenic embolism (cryptogenic ischemic stroke, TIA, systemic embolism or silent ischemic lesions on MRI)
Participants
1,245 patients
Outcome
Recurrent ischemic stroke, TIA or systemic embolism
Follow-up
Mean 14.5 ± 2.4 years

Main finding

As reported in the abstract

Patients with recurrent ischemic stroke, TIA or systemic embolism

34 (2.7%)

Recurrence rate

0.19 per 100 patient-years

Observational data: associations, not effects.
