Approaches to correct device malposition in percutaneous PFO closure: anatomical and technical implications.
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.
