InjurySep 28, 2026Adverse Event Without Identified Device or Use Problem
Patient problems: Loss of consciousness; Pain; Syncope/Fainting
MAUDE report 50926592 ↗InjurySep 24, 2026Signal Artifact/Noise; High impedance; Over-Sensing; Inappropriate/Inadequate Shock/Stimulation
It was reported that this cardiac resynchronization therapy defibrillator (CRT-D) and the right ventricular (RV) lead delivered an inappropriate shock due to oversensing of noise. Also, there was a high out of range shock impedance, greater than 200 Ohms. It was noted that during the defibrillation threshold (DFT) test at device implant, there was a high out of range shock impedance, greater than 200 Ohms. The field representative resolved the noise on the RV lead by reprogramming the device. This CRT-D and this RV lead were subsequently explanted due to these observations. This CRT-D was replaced. No additional adverse patient effects were reported.
Patient problems: Shock from Patient Lead(s)
MAUDE report 50884379 ↗MalfunctionSep 23, 2026Signal Artifact/Noise; Over-Sensing
It was reported that this cardiac resynchronization therapy defibrillator (CRT-D) exhibited oversensed noise and pacing inhibition. The patient experienced dizziness. Technical Services (TS) was contacted and noted that the noise appeared to be electromagnetic interference (EMI). TS also recommended follow up. This CRT-D remains in service. No additional adverse patient effects were reported.
Patient problems: Asystole
MAUDE report 50869893 ↗InjurySep 17, 2026Failure to Capture; Insufficient Device Problem Information; High Capture Threshold
Patient problems: No Clinical Signs, Symptoms or Conditions
MAUDE report 50812530 ↗MalfunctionSep 17, 2026Failure to Capture; High impedance; High Capture Threshold
It was reported that this cardiac resynchronization therapy defibrillator (CRT-D) and left ventricular (LV) lead exhibited pacing impedance measurements that were high and out of range, as well as loss of capture (LOC). It was noted that evaluation of the LV lead for possible replacement was planned. The patient was programmed to right ventricular (RV) only pacing. This CRT-D and LV lead remain in service. No adverse patient effects were reported.
Patient problems: Inflammation; Swelling/ Edema
MAUDE report 50798181 ↗MalfunctionSep 8, 2026Failure to Capture; Failure to Read Input Signal
Patient problems: No Clinical Signs, Symptoms or Conditions
MAUDE report 50678900 ↗MalfunctionSep 4, 2026Signal Artifact/Noise; Over-Sensing; Pacing Problem
Patient problems: Asystole
MAUDE report 50612127 ↗InjurySep 4, 2026Failure to Capture; Over-Sensing; High Capture Threshold
It was reported that this cardiac resynchronization therapy defibrillator (CRT-D) system was scheduled for battery replacement. During the procedure, the non Boston Scientific left ventricular (LV) lead showed no capture in LV only at 7.5 V, however LV capture in was observed in temp brady while in VOO mode. It was determined that LV sensing was programmed off due to right atrial (RA) oversensing, and the LV EGM appeared flat during LV threshold testing and temp brady. The only difference was that RVS was allowed during the threshold test, which reset the timing. During the battery replacement procedure, three distinct morphologies were observed. Further testing was performed in right ventricular (RV) only pacing, which had similar capture to the LV. None of the LV ring configurations had capture and the cause was not identified. CRT-D explant was completed successfully. No additional adverse patient effects were reported. Product return was requested.

Patient problems: Unspecified Infection
MAUDE report 50207590 ↗DeathAug 6, 2026Over-Sensing; Pacing Problem; Defibrillation/Stimulation Problem
It was reported that the patient had an ablation procedure for ventricular tachycardia (VT) on (b)(6) 2026. Subsequent to the ablation, on (b)(6) the patient was going in and out of slow VT; the cardiac resynchronization therapy defibrillator (CRT-D) was set to 100 beats/minute in an effort to pace through the VT. Burst pacing was tried and the patient's arrhythmia accelerated, requiring a shock, which successfully converted. A Lidocaine drip and propranolol were also administered. It was planned at the time to examine further medical management for the patient. The VT returned and it was observed that the left ventricular lead (LV) was inhibiting pacing. Technical Services discussed that it was likely health-related. It was further reported that this patient passed away on (b)(6) 2026. The patient was to be cremated, and it was not stated whether the device system would be returned. Additional information is being requested.
Patient problems: Tachycardia
MAUDE report 50165504 ↗InjuryJul 29, 2026Pacing Problem; Inappropriate/Inadequate Shock/Stimulation
It was reported that the patient with this cardiac resynchronization therapy defibrillator (CRT-D) received anti-tachycardia pacing (ATP) and multiple shocks for supraventricular tachycardia (SVT) episodes. Therapy was exhausted. This CRT-D remains in service. No additional adverse patient effects were reported.
Patient problems: Shock from Patient Lead(s)
MAUDE report 50070998 ↗InjuryJul 27, 2026Unexpected Therapeutic Results
It was reported that the patient implanted with this cardiac resynchronization therapy defibrillator (CRT-D) system presented to the emergency room (ER), and review of the presenting electrogram (EGM) showed possible left-sided ventricular tachycardia (VT). A full device interrogation was planned for later that day. Additional information received reported that the patient was found to be in slow VT below the programmed detection rate, and the patient was was externally cardioverted to normal sinus rhythm successfully. This CRT-D remains in service. No additional adverse patient effects were reported.

Patient problems: Syncope/Fainting
MAUDE report 25847638 ↗InjuryJul 15, 2026High impedance; Incorrect, Inadequate or Imprecise Result or Readings; Failure to Convert Rhythm
IT WAS REPORTED THAT THE PATIENT WITH THIS CARDIAC RESYNCHRONIZATION THERAPY DEFIBRILLATOR (CRT-D) AND THE RIGHT VENTRICULAR (RV) LEAD EXPERIENCED A MYOCARDIAL INFARCTION. THIS CRT-D PROVIDED EIGHT SHOCKS THAT DIDN'T CONVERT THE RHYTHM. EMERGENCY MEDICAL SERVICES (EMS) PERFORMED CARDIOPULMONARY RESUSCITATION (CPR) AND DELIVERED AN EXTERNAL SHOCK TO THE PATIENT. THE FIELD REPRESENTATIVE (REP) INTERROGATED THE DEVICE AND OBSERVED AN OPEN CIRCUIT ALERT. ALSO, THE RV LEAD EXHIBITED A HIGH OUT OF RANGE SHOCK IMPEDANCE, THAT WAS SUSPECTED TO BE GREATER THAN 145 OHMS. THE SHOCK WAS MONOPHASIC AND ENERGY WAS TRUNCATED. THE PATIENT WAS TRANSFERRED TO A LEVEL ONE TRAUMA CENTER FOR A LEFT VENTRICULAR ASSIST DEVICE (LVAD) AND POSSIBLE TRANSPLANT.

There were no device issues. No additional adverse patient effects were reported.
Patient problems: No Clinical Signs, Symptoms or Conditions
MAUDE report 25766995 ↗InjuryJul 8, 2026High impedance; Failure to Convert Rhythm; Defibrillation/Stimulation Problem
IT WAS REPORTED THAT THE PATIENT WITH THIS CARDIAC RESYNCHRONIZATION THERAPY DEFIBRILLATOR (CRT-D) SYSTEM EXPERIENCED A VENTRICULAR FIBRILLATION EPISODE IN WHICH ALL PROGRAMMED SHOCKS WERE EXHAUSTED WITHOUT SUCCESSFUL CONVERSION.
