Recent adverse event reports
The 25 most recent of 996 reports, in the reporter's own words as published by the FDA.
MalfunctionSep 24, 2026Failure to Capture
It was reported that the patient presented to hospital for an implant procedure. During the procedure, despite multiple repositioning attempts, it was noted that the left ventricular (LV) lead exhibited loss of capture. The LV lead was not used and was replaced on (b)(6) 2026. The patient was in stable condition.
Patient problems: No Clinical Signs, Symptoms or Conditions
MAUDE report 50879102 ↗MalfunctionSep 23, 2026Separation Failure; Device Dislodged or Dislocated
It was reported that the patient presented to the hospital for a scheduled implant procedure. During the procedure, the guidewire could not be separated from the left ventricular (LV) lead, resulting in lead dislodgement. Fluoroscopy confirmed the lead dislodgement. The physician attempted to use a different guidewire; however, this was unsuccessful. The LV lead was removed and replaced. The patient remained in stable condition.
Patient problems: No Clinical Signs, Symptoms or Conditions
MAUDE report 50864824 ↗InjurySep 23, 2026Adverse Event Without Identified Device or Use Problem
It was reported that the patient presented to the hospital with infection and endocarditis at device pocket. The infection was not associated with any Abbott product and/or procedure. The endocarditis was confirmed via diagnostic imaging. The whole system was explanted and replaced. The patient was in stable condition throughout the procedure.
Patient problems: Unspecified Infection
MAUDE report 50864474 ↗MalfunctionSep 16, 2026High impedance
It was reported that the patient presented for an implant procedure. During the procedure, the left ventricle lead exhibited high pacing impedance. The lead was not used and replaced. The patient was in stable condition.
Patient problems: No Clinical Signs, Symptoms or Conditions
MAUDE report 50788928 ↗MalfunctionSep 2, 2026Failure to Capture; High impedance; Therapy Delivered to Incorrect Body Area; Low impedance
Patient problems: Discomfort
MAUDE report 50572861 ↗MalfunctionAug 28, 2026High impedance; Device Sensing Problem
It was reported that during an implant procedure, the left ventricle (LV) exhibited high pacing impedance and R-wave amplitude variation at several different locations. As a result, the LV lead was not used and it was replaced with a new lead. The patient had no consequences.
Patient problems: No Clinical Signs, Symptoms or Conditions
MAUDE report 50492308 ↗MalfunctionAug 27, 2026Failure to Capture; Therapy Delivered to Incorrect Body Area; Under-Sensing
It was reported that the patient presented for an implant procedure. During the procedure, it was noted that the left ventricular lead exhibited a low R-wave amplitude, resulting in under-sensing. The lead also exhibited a high capture threshold with phrenic nerve stimulation, resulting in patient discomfort. The high capture threshold subsequently resulted in loss of capture. The lead was not used, and the procedure was completed with a conventional Dual-Chamber Implantable Cardioverter Defibrillator (DICD) implantation. The patient was discharged.
Patient problems: Discomfort
MAUDE report 50468466 ↗MalfunctionAug 12, 2026Failure to Capture; Fracture; High impedance; Therapy Delivered to Incorrect Body Area; Low impedance
During a remote follow-up, decreased and increased pacing impedance resulting in muscle stimulation and a loss of capture (LOC) were observed on the left ventricular (LV) lead. Conductor fracture was suspected but not confirmed. The device was then programmed into right ventricle (RV) stimulation only to resolve the event. The patient is stable.
Patient problems: Discomfort

MAUDE report 25453437 ↗DeathJun 8, 2026Adverse Event Without Identified Device or Use Problem
IT WAS REPORTED THAT THE PATIENT WAS DEPENDENT ON THE DEVICE FOR NORMAL FUNCTION. IT WAS REPORTED THAT THE PATIENT WENT INTO VENTRICULAR TACHYCARDIA (VT) IN THE MONITOR ZONE. THE VT PROGRESSED TO SLOW VENTRICULAR FIBRILLATION (VF) AND DEGENERATED INTO A FINE VF.
