Silent Lead Malfunction Detected Only During Defibrillator Replacement

Abstract: A 54-year-old man with right ventricular (RV) arrhythmogenic dysplasia and episodes of sustained ventricular tachycardia (VT) was admitted at another institution, where he underwent a RV biopsy complicated by an RV perforation and tamponade. A thoracotomy was performed and the RV was sutured. Soon afterward, he developed a superior vena cava syndrome. Several weeks later, a Medtronic GEM 7221 ICD was implanted via a thoracotomy at a left prepectoral site. A Medtronic Transvene RV 6936 tripolar lead (two sensin… Show more

“…In this case, implant failure would not have been recognized if not for the routine performance of DFT testing. The present report mirrors a previous one of silent lead malfunction, albeit in a standard caliber lead, that was only unveiled on DFT testing 5 . The role of DFT testing at first implant will be clarified by an ongoing multicenter, randomized, controlled clinical trial.…”

“…The present report mirrors a previous one of silent lead malfunction, albeit in a standard caliber lead, that was only unveiled on DFT testing. 5 The role of DFT testing at first implant will be clarified by an ongoing multicenter, randomized, controlled clinical trial. Whatever the outcome, the current case report suggests that DFT testing at generator change may identify the need for lead revision.…”

“…For arc marks to be seen, both the outer and the inner ethylene tetrafluoroethylene (ETFE) insulation layers of the ICD lead must be abraded to bare the metal of the RV coil conductor. In Goldstein's case [2], an inappropriate shock caused by noise was reported, suggesting an HV conductor fracture or failure of the pace–sense conductor [5]. However, the authors did not report any electrical abnormality in the pacing or shock systems, which argue against fracture of the conductors.…”

“…From a total of 445 references that were identified through electronic database searches, there were seven case reports [14][15][16][17][18][19][20] and one case series 21 which specifically reported outcomes and complications during DFT testing at ICD generator replacement. The majority of the reports were contemporary, being published from 2012 onwards.…”

“…However, data regarding DFT testing during new ICD implants may not be directly applicable to generator replacement because chronically implanted ICD leads may develop integrity issues over time . Although several reports have cautioned against the abandonment of DFT testing during generator replacement, the issue has been sparingly addressed in the existing literature.…”
