Bridge to recovery using an Impella 2.5 device in a 3-year-old child

Area of Science:

• Pediatric cardiology
• Mechanical circulatory support
• Cardiac transplantation

Background:

• Mechanical support for pediatric acute left ventricular failure is limited, primarily to extracorporeal life support (ECLS) or ventricular assist devices (VADs).
• Acute humoral rejection post-cardiac transplantation can lead to persistent low cardiac output syndrome, posing significant management challenges in children.

Observation:

• A 3-year-old child (12 kg) presented with persistent low cardiac output syndrome due to acute humoral rejection after cardiac transplantation, unresponsive to medical therapy.
• The clinical team opted for an alternative mechanical support strategy due to the limitations of conventional options.

Findings:

• A 2.5 version of the Impella device was successfully implanted using a 6-mm Hemashield prosthesis in the right axillary artery.
• This intervention effectively stabilized the patient's hemodynamics, providing crucial support.

Implications:

• This case demonstrates the potential utility of the Impella 2.5 device as a bridge to recovery in pediatric patients experiencing severe low cardiac output syndrome post-cardiac transplantation.
• The successful application highlights a potentially viable alternative mechanical circulatory support option in challenging pediatric cardiac scenarios.
• Further investigation into the use of percutaneous ventricular assist devices in pediatric transplantation is warranted.
