What this Trial Is About
This research focuses on patients with embolic stroke of undetermined source (ESUS) linked to patent foramen ovale (PFO), particularly addressing the treatment gap for those aged 60 years and older. It aims to compare the safety and effectiveness of PFO closure against direct oral anticoagulants (DOACs) or antiplatelet agents for preventing recurrent strokes. The study combines a retrospective cohort from 2013 to 2025 and a prospective cohort from 2025 to 2031, involving approximately 900 adults aged 18 to 90 years with ESUS and confirmed PFO. Participants receive treatments determined by local investigators, including transcatheter PFO closure using the Amplatzer device plus antiplatelet therapy, standard-dose DOACs, or antiplatelet drugs when DOACs are contraindicated. The prospective arm emphasizes patients aged 60 and above with high-risk PFO features. Treatment groups include younger or older patients receiving either medical therapy alone or PFO closure with antiplatelet therapy. During the study, participants undergo clinical evaluations, imaging, cardiac tests, biomarker and genetic data collection, and optional atrial cardiopathy assessments over 3 years. Researchers monitor recurrent ischemic stroke or transient ischemic attack as the primary outcome, alongside functional outcomes, all stroke events, safety endpoints like new atrial fibrillation, and mortality. This comprehensive data collection aims to improve risk prediction and guide individualized treatment choices for PFO-related stroke.

Your Study Journey
Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Duration - Long-term as determined by routine care
Participants receive transcatheter PFO closure with the Amplatzer PFO occluder device followed by long-term antiplatelet therapy including dual antiplatelet treatment for at least 3 months and lifelong single antiplatelet therapy.
Approximately 6 post-operative visits
Duration - Long-term as determined by routine care
Participants treated with standard dose direct oral anticoagulants (DOAC) or antiplatelet therapy if DOAC is contraindicated, as part of routine care for stroke prevention.
Visit frequency depends on routine clinical practice
Duration - Up to 3 years
Participants are observed over time to monitor for recurrent stroke, functional outcomes, atrial cardiopathy, and safety events including new-onset atrial fibrillation and major bleeding.
Visits scheduled at least every 6 months for assessments
