The patent foramen ovale (PFO) is a normal interatrial communication during fetal life that remains after birth in nearly 20 % of adults. Percutaneous transcatheter PFO closure has been performed for various compelling reasons for more than two decades. The complication rate related to the use of these percutaneous devices has decreased remarkably with the use of new devices and the availability of tertiary care centers. Nevertheless complications do occur and rarely can be fatal. The purpose of this review is to summarize the major complications that happen during and after percutaneous PFO closure, their incidence among different devices, clinical implications, diagnosis and treatment.
