The reported event of pacing issue was confirmed.Continuity testing found that a short condition occurred in the catheter body.Cut down was performed and revealed that the insulation of proximal lead wire was missing from under the proximal electrode to 3.0 cm from catheter tip.Insulation of distal lead wire was partially missing from under the proximal electrode to 3.9 cm from catheter tip.This condition allowed the leadwires to make contact and caused the short condition.After separating both wires, no short condition was observed, and continuous condition was confirmed between distal electrode and distal connector pin and between proximal electrode and proximal connector pin.The balloon inflated clear and concentric and remained inflated for 5min.Without leakage.No visible damage was observed from catheter body, balloon, windings, and returned syringe.Further evaluation regarding related quality issues is under investigation.Complaint histories for all reported events are reviewed against trending control limits on a monthly basis and any excursions above the control limits are assessed and documented as a part of the monthly review.
