Atrial loop and absorbable ligatures may prevent it. Periodical lead advancement with lead pushing from the pocket may be an option to growth\u2010induced stretching. Our aim was to analyze retrospectively the outcome of periodical transvenous lead advancement in children with pacemaker (PM).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A procedure of lead advancement was performed in patients with a single\u2010chamber PM implanted for isolated congenital complete atrioventricular block or sinus node dysfunction with growth\u2010induced lead straightening\/stretching. The PM pocket was opened, the lead was released from subcutaneous adherences and was gently advanced to shape again a loop\/semi\u2010loop in the atrium without dislodging the tip. Lead data (threshold, sensing, impedance) were compared before and after the procedure. Data are described as median (25th\u201375th centiles).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>14 patients with 13 VVIR and 1 AAIR PM implanted at 6.8 (5.9\u20138.0) years of age, 23 (19\u201326) kg, 118 (108\u2013124) cm, underwent 30 advancement procedures, 1.5 (1.0\u20132.3) per patient, during follow\u2010up [45 (35\u201363) months]. Delta between procedures was: 18 (14\u201325) months, 11 (7\u201313) cm, 6 (4\u20139) kg; 90% of leads were successfully advanced without complications.
