Recurrent events following patent foramen ovale closure in patients above 55 years of age with presumed paradoxical embolism.

Objectives: The aim of this article is to summarize our experience of patent foramen ovale (PFO) closure in patients above the age of 55 years.

Background: PFO is associated with cryptogenic thromboembolic events (TEs) in patients younger than 55 years. Little is known about the recurrence rate of TE in patients above the age of 55 years undergoing PFO closure for presumed paradoxical embolism.
