It was reported that, during generator changeout procedure, while suturing the pocket, the right ventricular (rv) lead was, "barely moved at the time of suturing," but the physician was not informed at that time and the pocket was closed.Post pocket closure device check, showed a right ventricular (rv) lead high and undefined bipolar lead impedance, with unchanged unipolar impedance.X-ray revealed that the right ventricular (rv) lead was not connected fully to the rv port.Re-operation was performed and the rv lead was re-connected to the rv port, with good measured values and both the rv lead and the implantable pulse generator (ipg) remain in use.A reported possible additional cause of the disconnection included lack of slack on the rv lead, creating pressure while torque was being applied.No patient complications have been reported as a result of this event.
