UNASSIGNED: @entity616 ( @entity616 ) occurred the day after interventional closure of an @entity2438 with a 30 mm Gore Septal Occluder (GSO   ) in a 2 years and 11-month-old female. @entity616 disappeared without further treatment and stable sinus rhythm recovered within 3 days. Only short episodes of 2nd degree @entity713 (Wenckebach periodicity) at rare intervals were documented in Holter-monitors the following 2 months. Eleven months after device implantation the @entity1 suffered from long lasting episodes of @entity616 . Surgical removal of the device resulted in incomplete recovery of AV-conduction. Histopathological work-up of the explanted GSO showed complete endothelialization of the device and regular scar formation. One year after surgery, the @entity1 had sinus rhythm during daytime but needed VVI-pacing while sleeping. Young age, inferior localization of the defect, and use of a large device have been individual risk factors for @entity616 in this @entity1 . Clinical course and histologic findings indicate that mechanical compression was the only cause for @entity616 . The cumulative number of reports of @entity616 after use of different @entity2438 -devices supports the recommendation to postpone the intervention in asymptomatic @entity1 to preschool-age. Early removal of a pushing device may increase the chance of complete recovery from @entity616 .    2015 Wiley Periodicals, Inc.
