Cardiac Strangulation in Children: Asymptomatic Complication of Epicardial Pacing

Area of Science:

• Pediatric Cardiology
• Cardiovascular Surgery
• Biomedical Engineering

Background:

• Epicardial pacemaker implantation is a common procedure in pediatric patients requiring long-term pacing.
• Mechanical complications, though infrequent, can arise from implanted devices, particularly in growing children.
• Cardiac strangulation represents a severe, albeit rare, adverse event associated with these systems.

Observation:

• Two pediatric cases of left ventricular strangulation following early-age epicardial pacemaker implantation are presented.
• The patients, aged 4 and 3 years, developed this mechanical complication.
• The strangulation involved the left ventricle, indicating a significant impact on cardiac function.

Findings:

• The findings underscore the potential for cardiac strangulation as a serious complication of pediatric epicardial pacemaker systems.
• Early implantation in growing children appears to be a risk factor.
• Prompt recognition and management are crucial for patient outcomes.

Implications:

• This case series highlights the need for vigilance regarding mechanical complications in pediatric patients with epicardial pacemakers.
• Further research into device design and implantation techniques may be warranted to mitigate risks.
• Clinicians should consider cardiac strangulation in the differential diagnosis of unexplained symptoms in children with these devices.
