Event Description

A journal article was reviewed that contained information regarding epicardial implantable cardioverter defibrillator (icd) leads.The article reports sudden deaths which occurred during the follow up period.The deaths were not attributed to lead malfunctions, but they could not entirely rule it out whether a failed shock might have been the cause of death.There were lead malfunctions which included fractures and fluid within the lead insulation and were diagnosed via x-ray.The leads exhibited oversensing, failure to pace/capture, lack of defibrillation, or high impedance.Leads were revised or unknown intervention was performed.The status/disposition of the leads is unknown.No patient complications have been reported as a result of this event.
