Transcatheter retrieval and repositioning of embolized stent from the right ventricle in an infant

Area of Science:

• Cardiology
• Pediatric Cardiology
• Interventional Cardiology

Background:

• Intracardiac stent embolization presents significant challenges, particularly in infants.
• A Palmaz stent was implanted in a 3-month-old boy to address right-side heart failure due to atrial septal defect.

Observation:

• Post-implantation radiography revealed unexpected stent embolization into the right ventricle.
• This complication required prompt and effective intervention to prevent adverse outcomes.

Findings:

• Successful transcatheter retrieval and repositioning of the embolized Palmaz stent were achieved.
• The procedure was performed without any immediate or delayed complications in the infant.

Implications:

• Transcatheter intervention offers a viable, less invasive alternative to surgery for managing stent embolization in high-risk infants.
• This case highlights the feasibility and safety of endovascular techniques for complex pediatric cardiac interventions.
