  • Notas adicionales en la data
    According to the company, a portion of EnTrust Implantable Cardioverter Defibrillators (CDI's) may not meet the expected longevity or provide at least three months of device operation between the Elective Replacement Indications (ERI) and their lifetime (EOL ), due to a faster than expected fall in battery voltage. The company has not received reports of patient death or serious injury as a result of this problem. The events reported refer to a drop in battery voltage from ~ 3.0 V to ERI (2.61 V) over a period of time ranging from approximately one week to six months. All events reported occurred at least 30 months after the implant. Medtronic has confirmed nine reports of time-out of the load circuit during automatic capacitor rebuilding and a report of loss of pacing, all occurring between the ERI and the explant moment. Although there is a potential risk of high voltage loss between ERI and the explant of the device, such fact has not been reported to date according to the company. Medtronic has identified the cause of these occurrences as being a short internal battery, which occurs as the battery capacity is consumed. #### Update (08/17/2012): The record holder finalized risk communication to users of the product, as reported to UTVIG (Exp .: 0441135 / 12-8).
  • Causa

    Treatment recommendations: Physicians should keep routine follow-up sessions at least every three months in accordance with the instructions for use of the product. Patient alerts must also be programmed for "Low Battery Voltage ERI" and "Excessive Charge Time EOL" to ON and immediately replace devices after reaching ERI if the voltage reduction is faster than expected. Entity Proactive / Proactive Replacements are not recommended.
