Description
Summary:BACKGROUNDThe Attain Stability Quadripolar 4798 lead is a relatively new quadripolar active fixation coronary sinus (CS) lead. No cases of extraction of a chronically implanted 4798 lead have been published to date. CASE SUMMARYA 52-year-old man with a history of previous cardiac resynchronization therapy pacemaker (CRT-P) insertion and atrioventricular node ablation presented to our institution with a pocket infection 69 weeks after implantation. Directed intravenous antibiotic therapy was commenced and an extraction was performed the following day. Extraction of the right atrial and right ventricular leads was simple and achieved with gentle manual traction. Extraction of the CS lead was more difficult. Significant traction was required due to the formation of adhesions inside the CS but extraction of the lead was eventually successful without complication. Specialized extraction equipment was not required. A new contralateral CRT-P device was implanted, and the patient was discharged home. He remains well at 3 months of follow-up. DISCUSSIONWe present the first case of extraction of a chronically implanted active fixation Attain Stability Quadripolar lead. Our experience demonstrates that this has been performed successfully without specialist tools and with preservation of the CS branch. Significant adhesion was noted at the site of active fixation, however. Potential difficulty with this lead's extraction should therefore be considered when contemplating its use.
