Frequency and clinical impact of retained implantable cardioverter defibrillator lead materials in heart transplant recipients.

| Abstract |
End-stage heart failure patients with implantable cardioverter-defibrillator (ICD) with/without cardiac resynchronization therapy (CRT-D) often require heart transplantation (HTPL) as a last-resort treatment. We aimed to assess the frequency and clinical impact of retained ICD lead materials in HTPL patients. In this retrospective single center study, we examined the clinical records and chest radiographs of patients with ICD and CRT-D who underwent HTPL between January 1992 and July 2014. Of 40 patients with ICD and CRT-D at HTPL, 19 (47.5%) patients had retained ICD lead materials within the central venous system. Retained ICD lead materials following HTPL were more frequently noted in patients with longer implantation durations until HTPL. None of the patients underwent extraction procedures after HTPL. All patients were asymptomatic and did not exhibit significant complications or death related to the retained ICD lead materials. Seven (7/40, 17.5%) patients without any retained ICD lead materials underwent magnetic resonance imaging (MRI) during the follow-up period (median, 29.5 months); none of the patients with retained lead materials were given MRI. Considering the common use of MRI in HTPL patients, further studies on the prophylactic extraction of retained ICD lead materials and safety of MRI in these patients are needed.
