Transvenous pacing in pediatric patients with bipolar lumenless lead: Ten-year clinical experience.

INTRODUCTION

A number of challenges can affect long-term performance of endocardial implanted systems in pediatric patients. Select Secure™ lead offers potential advantages for this population. This analysis aims to evaluate long-term performance of this lead in children, with and without congenital heart disease.

METHODS

A retrospective analysis of all patients younger than 16years, implanted with at least one Select Secure™ lead at our institution, was performed. Clinical patient characteristics, electrical lead parameters, implant related complications, occurrence of surgical revisions and other complications were analyzed.

RESULTS

From 2006 to 2016, 40 pediatric patients (26 males; age: 10.3±4.6years) underwent a cardiac device implantation with at least one Select Secure™ lead. Axillary vein access was chosen in 77.5% of the procedures. The intra-atrial loop of the leads was successfully created and the generator was placed in a sub-pectoral pocket in all patients. A total of 57 Select Secure™ leads were implanted: 23 in the right atrium and 34 in the right ventricle. PM/ICDs implantation was uneventful in all 40 patients. One lead, dislodged the day after implantation, was successfully extracted and replaced in the same day. Adequate pacing parameters were achieved during a follow-up of 6±2.9years (range 0.9-10.8years).

CONCLUSIONS

In a pediatric population, the Select Secure™ lead used in the axillary vein, the creation of an intra-atrial loop and the placement of the generator in a sub-pectoral pocket ensured a safe implantation of pacemaker or ICD and an effective stimulation at medium-term follow-up.
