A “long-standing” malpositioned pacing lead. Long-term follow-up after extraction

Transvenous pacemaker (PM) catheters can be unintentionally placed in the left ventricle (LV) during the implantation procedure. An 8-year-old girl was discovered with a malpositioned pm wire, seven years after the implant. Trans-thoracic echocardiogram revealed the lead traversing the inter-atrial septum, crossing the mitral valve and embedded in the basal lateral wall of the LV. This is a report of a 14-year long follow-up after the surgical extraction of the malpositioned PM lead. come easier. Although nowadays a transvenous lead can be placed in children, there is a greater risk of complication in small patients [3]. One extremely rare complication associated with transvenous PM implantation is the inadvertent positioning of pacing lead in the left ventricle [4]. The greater risks depend on the delay of diagnosis of lead malpositions. This report concerns a case of long standing malpositioned PM wire in a paediatric patient and the successive long term follow up after the successful surgical extraction.
