Mechanical circulatory support for infants and small children

Area of Science:

• Pediatric Cardiology
• Cardiovascular Surgery
• Biomedical Engineering

Background:

• Increasing survival rates in pediatric congenital heart disease patients have led to a greater need for mechanical circulatory support.
• Primary myocardial dysfunction (e.g., myocarditis, dilated cardiomyopathy) can cause end-stage cardiac failure in pediatric patients.
• Mechanical circulatory support is used temporarily for recovery or long-term as a bridge to heart transplantation.

Purpose of the Study:

• To review the specific challenges and available devices for pediatric mechanical circulatory support.
• To report on the global increase in use and outcomes associated with these devices.
• To provide insights into future developments and remaining challenges in the field.

Main Methods:

• Review of current literature on pediatric mechanical circulatory support.
• Analysis of device types, including extracorporeal membrane oxygenation (ECMO) and ventricular assist devices (VADs).
• Examination of outcomes based on indication and device type.

Main Results:

• Extracorporeal membrane oxygenation (ECMO) is used for short-term support.
• Ventricular assist devices (VADs) provide long-term support as a bridge to transplantation.
• The use of these devices has grown significantly worldwide.

Conclusions:

• Pediatric mechanical circulatory support is a rapidly evolving field with improving outcomes.
• Technological advancements have expanded options for managing pediatric end-stage heart failure.
• Further research is needed to address ongoing challenges and optimize patient care.
