2016
ABSTRACTIntroduction: Patent foramen ovale (PFO) is a common congenital cardiac abnormality and that has been associated with several disease processes including transient ischemic attacks (TIA), stroke, migraine headaches with aura, decompression sickness, platypnea-orthodeoxia syndrome, and shunt induced cyanosis. Controversy exists regarding closure of PFO as a therapeutic treatment modality for these disease processes. This review addresses the contemporary clinical indications for PFO closure.Areas covered: We conducted a comprehensive literature search of contemporary research studies focusing on randomized trials and meta-analyses comparing medical therapy and device closure of PFOs for the treatment of PFO associated clinical syndromes. We synthesized this literature into a review addressing indications for PFO closure in stroke, TIA, migraine headaches with aura, decompression sickness, platypnea-orthodeoxia syndrome, and shunt induced cyanosis.Expert commentary: Because in many PFO associated co...
