Minimally invasive technique of placing a dual chamber permanent pacemaker in children

OBJECTIVE: To share the experience of a minimally invasive technique in the implantation of a dual chamber permanent pacemaker in paediatric population. METHODS: The retrospective study was conducted at Aga Khan University Hospital, Karachi, and comprised data of patients aged up to 16 years who underwent epicardial dual chamber permanent pacemaker insertion via xiphisternal incision between April 2011 and August 2016. Demographic data included age, weight and gender of the patient. Indications for pacemaker insertion, electrocardiography findings, concomitant cardiac procedures and procedural complications were reviewed. Pacemaker thresholds and impedance at the time of implantation and throughout the course of follow-up were extracted from the clinical data. RESULTS: Of the 10 patients, 5(50%) were males and 5(50%)were females. The overall mean age was 3.4�}3.8 years (range: 1 month - 13 years). The mean weight at the time of operation was 11.4�}6.8 kg (range: 4.3-27kg). Indications for permanent pacemaker insertion included postoperative advanced or complete atrioventricular block in 7(70%) and complete congenital heart block in 3(30%). There was no reported morbidity. CONCLUSIONS: Dual chamber permanent pacemaker insertion via xiphisternal incision was found to be of benefit to the patients and the surgeons alike.
