- Transvenous lead advancement in pediatric pacing to overcome growth‐induced lead straightening and stretching Massimo Stefano Silvetti Luigina Porco Marta Campisi Vincenzo Pazzano Ilaria Tamburri Fabio Anselmo Saputo Giacomo Silvetti Lucilla Ravà Fabrizio Drago Pacing and Clinical Electrophysiology Abstract Background The stretching of the lead caused by somatic growth may lead to complications (dislodgement, fracture, failure) of transvenous leads implanted in pediatric patients. Atrial loop and absorbable ligatures may prevent it. Periodical lead advancement with lead pushing from the pocket may be an option to growth‐induced stretching. Our aim was to analyze retrospectively the outcome of periodical transvenous lead advancement in children with pacemaker (PM). Methods A procedure of lead advancement was performed in patients with a single‐chamber PM implanted for isolated congenital complete atrioventricular block or sinus node dysfunction with growth‐induced 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‐loop 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–75th centiles). Results 14 patients with 13 VVIR and 1 AAIR PM implanted at 6.8 (5.9–8.0) years of age, 23 (19–26) kg, 118 (108–124) cm, underwent 30 advancement procedures, 1.5 (1.0–2.3) per patient, during follow‐up [45 (35–63) months]. Delta between procedures was: 18 (14–25) months, 11 (7–13) cm, 6 (4–9) kg; 90% of leads were successfully advanced without complications. Three unsuccessful procedures occurred with longer times [30 (14–37) months]. Electrical lead parameters did not show significant differences pre‐/post‐procedures. Conclusion the advancement of transvenous leads in children seems safe and effective. This procedure may be another possible choice to preserve transvenous lead position and function until growth has completed. 10.1111/pace.14979 http://onlinelibrary.wiley.com/termsAndConditions#vor
