Objective:
This study aimed to present our experience with surgically implanted cardiac implantable electronic devices (CIED) in infants.
Methods:
Thirty-eight infants (18 males, 20 females; mean age: 155.6±102.2 days; range, 1 to 343 days) who underwent a surgical procedure to implant CIEDs between 2014 and 2024 were included in the study. Pre-, intra-, and postoperative data were collected and analyzed.
Results:
The mean weight was 5.27±1.99 kg (range, 2.1 to 9 kg). Twenty-four (63%) patients required CIED due to complete atrioventricular block after pediatric heart surgery. In five (13%) patients, the indication was congenital complete atrioventricular block. Remaining 10 (24%) patients had a long QT, congenitally corrected transposition of the great arteries, and cardiomyopathy. Pacemaker configuration was VVI in 31 (81.5%) patients, ICD in three (8%) patients, CRT in two (5.25%), and DDD in two (5.25%). The median follow-up was five years (range, 1 to 10 years). There were no deaths. A total of 12 reoperations were required in seven (18.4%) patients when pacemaker generator replacements were excluded. Five reoperations were related to lead fracture and revision. The remaining seven reoperations were to either upgrade or downgrade pacemaker configurations.
Conclusion:
In patients younger than one year, surgical implantation of CIEDs represents a safe procedure with reasonably acceptable outcomes in the mid-term follow-up. However, reoperations are inevitable, and appropriate reinterventions depend on close device surveillance.
