Patent foramen ovale should be considered in the differential diagnosis of patients presenting with transient loss of consciousness.
Patent foramen ovale (PFO) is a congenital heart condition with a prevalence of 20%-35% in the general population. It is associated with various paroxysmal neurological seizures. We report four patients who presented to our hospital with transient loss of consciousness (TLOC). They were diagnosed with PFO after a comprehensive examination. In this article, we discuss the mechanism related to PFO and TLOC, which provides a new clinical perspective for the diagnosis of TLOC.
