Propensity-score matched analysis of patent foramen ovale closure in real-world study cohort with cryptogenic ischemic stroke.

Introduction: Patent foramen ovale (PFO) occurs in 25% of the general population and in 40% of cryptogenic ischemic stroke patients. Recent trials support PFO closure in selected patients with cryptogenic stroke. We examined the outcomes of transcatheter PFO closure in a real-world study cohort with cryptogenic stroke.
