title: Approaches to correct device malposition in percutaneous PFO closure: anatomical and technical implications.
abstract: We describe three patients with initial failure of transcatheter patent foramen ovale closure. Two patients had residual defects successfully closed during the initial session, and one patient had a persistent shunt, which was corrected at a later time. Anatomical and technical considerations and the role of intracardiac ultrasound are discussed.
