Related manufacturer reference number: 2017865-2020-16191.It was reported that the patient presented to the emergency room complaining of weakness.Interrogation of the implantable cardioverter defibrillator (icd) revealed that the right ventricular (rv) lead was unable to pace.An x-ray revealed that the rv lead had dislodged into the superior vena cava, and that the icd was pointing in the opposite direction as it did when first implanted, indicating twiddler's syndrome.The device was reprogrammed and the patient was monitored until the rv lead revision occurred.During the procedure, the lead was attempted to be repositioned but the helix was difficult to retract and extend, so the lead was cut, explanted, and replaced.The patient was in stable condition throughout.
