  • Case Report Pacemaker Failure Due to Loss of Fluid Seal in a Patient with a 5/6mm Pacemaker Header Port and a 5mm Unipolar Lead
    2016
    Co-Authors: Paul Chun, Boon Yew Tan, Chee Keong Ching, Yih Lim, Wee Siong Teo
    Abstract:

    Introduction: Before IS-1 (3.2 mm) standardization of Pacemaker leads and connectors, 5/6 mm connector ports accomodated 5mm or 6mm diameter lead connector pins. Case report: A patient with sick sinus syndrome underwent implantation of a 5mm unipolar atrial lead, mated to a 5/6mm connector port Medtronic Spectrax Sx 5985 Pacemaker. Pulse generator reached ERI in 2006, with change out to a Medtronic Sigma SSR306 (5/6m

    Abstract:

Case report A patient with sick sinus syndrome underwent implantation of a 5mm unipolar atrial lead, mated to a 5/6mm connector port Medtronic Spectrax Sx 5985 Pacemaker. Pulse generator reached ERI in 2006, with change out to a Medtronic Sigma SSR306 (5/6mm connector port) and preservation of the 5mm lead. She was admitted in 2010 for atrial lead non capture from blood leak and corrosion of the header-connector pin apparatus. Discussion 5/6mm Pacemaker header ports have a 5mm flexible sealing ring at the port entrance to seal 5mm or 6mm lead connector pins. The inner barrel diameter of the connector port is 6mm and insertion of a 5mm lead results in a 0.5mm tolerance circumferentially. Should the seal be compromised, blood can corrode the apparatus. To minimize this, we can employ (a) a cinching tie to further seal the silicone ring (b) universal adaptor sleeves (c) splice kits (d) lead adaptor kits. Aging leads, adaptor kits or sleeves themselves can result in lead Failure. It may be safer to re-implant the entire system. Conclusion A 5/6mm configuration Pacemaker header connector port allows for significant tolerances when a 5 mm lead is used. Consideration must be made to prevent leaks. (222 words)

  • the Pacemaker twiddler s syndrome an infrequent cause of Pacemaker Failure
    BMC Research Notes, 2016
    Co-Authors: Mohammad Salahuddin, Fathima Aaysha Cader, Sahela Nasrin, Mashhud Zia Chowdhury
    Abstract:

    The Pacemaker-twiddler’s syndrome is an uncommon cause of Pacemaker malfunction. It occurs due to unintentional or deliberate manipulation of the Pacemaker pulse generator within its skin pocket by the patient. This causes coiling of the lead and its dislodgement, resulting in Failure of ventricular pacing. More commonly reported among elderly females with impaired cognition, the phenomenon usually occurs in the first year following Pacemaker implantation. Treatment involves repositioning of the dislodged leads and suture fixation of the lead and pulse generator within its pocket. An 87 year old Bangladeshi lady who underwent a single chamber ventricular Pacemaker (VVI mode: i.e. ventricle paced, ventricle sensed, inhibitory mode) implantation with the indication of complete heart block, and presented to us again 7 weeks later, with syncopal attacks. She admitted to repeatedly manipulating the Pacemaker generator in her left pectoral region. Physical examination revealed a heart rate of 42 beats/minute, blood pressure 140/80 mmHg and bilateral crackles on lung auscultation. She had no cognitive deficit. An immediate electrocardiogram showed complete heart block with Pacemaker spikes and Failure to capture. Chest X-ray showed coiled and retracted right ventricular lead and rotated pulse generator. An emergent temporary pace maker was set at a rate of 60 beats per minute. Subsequently, she underwent successful lead repositioning with strong counselling to avoid further twiddling. Twiddler’s syndrome should be considered as a cause of Pacemaker Failure in elderly patients presenting with bradyarrythmias following Pacemaker implantation. Chest X-ray and electrocardiograms are simple and easily-available first line investigations for its diagnosis. Lead repositioning is required, however proper patient education and counselling against further manipulation is paramount to long-term management.
