Additional information: d10, h3, and h6.The reported complaint of failure to insert the left ventricular (lv) lead into the lv-connector was confirmed.Analysis testing revealed the lv-set screw was blocking the lead from being inserted into the lv-connector.Furthermore, analysis revealed that the lv-set screw was manipulated in the field.For analysis testing, the set screw was backed out from blocking the connector port.Is-4 test leads could then be fully inserted into the lv-connector with normal insertion force.All connector dimensions were within specification and no device anomalies were revealed.This can be considered a user-related anomaly since the user manual now states to retract the set screws in the device connector so the pacing lead terminal pins can be fully inserted.It also states that the user may make up to two rotations of the torque wrench to retract the set screw, which would have backed the set screw out from blocking the insertion of the lead.The device was revealed to be electrically normal.The battery voltage is above elective replacement indicator (eri) and is near beginning of life (bol).
