Event Description
|
It was reported that the patient feels that stimulation has been worse since the recent device implant.It was noted that the patient has a history of diaphragmatic stimulation since the initial implant of the left ventricular (lv) lead.The physician decided to adjust the left ventricular (lv) lead by reducing the lv output, though the threshold remains high.The patient is enrolled in the wrap-it (world-wide randomized antibiotic envelope infection prevention trial) study.No further patient complications have been reported as a result of this event.

Event Description
|
It was reported later that the device had premature battery depletion.It was noted that the device had less than one month estimated longevity from giving the patient appropriate therapy.It was suspected that the high left ventricular (lv) output and thresholds likely caused the premature battery depletion.Additionally, it was further reported that the patient had syncope associated with ventricular tachycardia.It was noted that the patient was walking and had a sudden onset of syncope.There was no warning sign whatsoever.The patient suddenly found themselves on the ground.At the time the patient was unaware of the implantable cardioverter defibrillator (icd) therapy shocks.The symptoms were sudden and rapid in onset.Lasted for less than three minutes.The patient was noted on remote monitoring to have had an episode of ventricular tachycardia, successfully stopped with a single defibrillation.The remote transmission also indicated that the device at that time was near eri (elective replacement indicator) with approximately one month longevity remaining.The device remained in use but plans for replacement of the device during hospital stay were made.The device was explanted and replaced the following day.It was noted that the patient refused a left ventricular (lv) lead revision.The patient is enrolled in the wrap-it (world-wide randomized antibiotic envelope infection prevention trial) study.No further patient complications have been reported as a result of this event.

Event Description
|
It was further reported that there was phrenic nerve stimulation due to the left ventricular (lv) lead.The lv lead was explanted and replaced.No further patient complications have been reported as a result of this event.

Manufacturer Narrative
|
Product event summary: the lead was not returned for analysis, however, performance data collected from the device was received and analyzed.Analysis of the device memory indicated pacing capture threshold in the left ventricle was high.Information is provided in the future, a supplemental report will be issued.
