One of the potential long-term pitfalls of a sturdy pacing lead is relative retraction with growth in children resulting in late lead dislodgement.<\/jats:p><\/jats:sec><jats:sec><jats:title>Case summary\u2003<\/jats:title><jats:p>We report two cases of late SelectSecure 3830 lead dislodgement at 11.8\u2009years (Case 1) and 8.8\u2009years (Case 2), respectively, post the initial implantation. Case 1 was diagnosed with congenital complete heart block (CHB) at 9 months old when he presented with unconfirmed diphtheria infection. Case 2 was diagnosed with CHB at 14\u2009weeks of age with positive maternal anti-Ro antibodies. Both patients underwent implantation of a transvenous permanent pacemaker implantation with Medtronic SelectSecure 3830 lead due to symptomatic bradycardia. Apart from a pulse generator change at 8.5\u2009years (Case 1) and 7\u2009years (Case 2), respectively, post-implant due to normal battery depletion, both patients are well in the
