Bridge to Heart Transplantation Using the Impella Device in a Pediatric Patient

Area of Science:

• Pediatric Cardiology
• Cardiovascular Surgery
• Medical Device Technology

Background:

• Limited mechanical circulatory support options exist for pediatric acute heart failure.
• Managing pediatric patients with heart failure presents unique size and support challenges.
• Left ventricular assist devices are sometimes required for pediatric extracorporeal support.

Purpose of the Study:

• To describe the successful use of a specific mechanical circulatory support device in a pediatric patient with acute heart failure.
• To demonstrate a viable bridging strategy to heart transplantation for pediatric patients with severe left ventricular dysfunction.

Main Methods:

• Implantation of an Impella 5.5 device in a 12-year-old patient with severe left ventricular dysfunction.
• Anterograde insertion of the device via a 10-mm Hemashield graft to the right innominate artery.
• Utilizing the device as a bridge to heart transplantation after failure of medical therapy.

Main Results:

• Successful stabilization of the pediatric patient with acute heart failure.
• The Impella 5.5 device effectively supported the patient's circulation.
• The patient was successfully bridged to a subsequent heart transplant.

Conclusions:

• The Impella 5.5 device can be a safe and effective mechanical circulatory support option for select pediatric patients with acute heart failure.
• This case highlights a successful strategy for bridging pediatric patients to heart transplantation when medical therapy fails.
• Advanced mechanical circulatory support devices offer promising solutions for complex pediatric cardiac conditions.
