Percutaneous patent foramen ovale closure lowers recurrent stroke and composite events versus antithrombotic therapy in patients with cryptogenic stroke (P<0.001), but increases atrial fibrillation.
Meta-Analysis
Does percutaneous patent foramen ovale closure reduce recurrent stroke and composite events in people with cryptogenic stroke compared with anti-thrombotic therapy?
PFO closure effectively reduces recurrent stroke and composite events in selected patients with cryptogenic stroke compared to antithrombotic therapy, though it carries a higher risk of atrial fibrillation.
p-value: p=<0.001
BACKGROUND: Stroke is a leading cause of death and disability. Patent foramen ovale (PFO) is more common in cryptogenic stroke, but the benefit of closure over antithrombotic therapy remains debated. We updated randomized evidence comparing PFO closure with antithrombotic therapy. METHODS: MEDLINE, Embase, and Cochrane Central were searched through September 2025. Primary outcomes were stroke, transient ischemic attack (TIA), and a composite of stroke, TIA, death, or systemic embolism. Serious adverse events and atrial fibrillation were assessed. RESULTS: < 0.001). CONCLUSION: In selected patients, PFO closure lowers recurrent stroke and composite events versus antithrombotic therapy, at the cost of higher atrial fibrillation.

Tewari et al. (Fri,) は、クリプトジェニック脳卒中におけるメタアナリシスを実施しました。経皮的卵円孔閉鎖と抗血栓療法を比較し、脳卒中、一過性脳虚血発作 (TIA)、および脳卒中、TIA、死亡、または全身塞栓症の合成指標を評価しました (p=<0.001)。経皮的卵円孔閉鎖は、クリプトジェニック脳卒中患者において、抗血栓療法と比較して再発脳卒中および合成事象を低下させます (P<0.001)、ただし心房細動は増加します。
