Insights

The new 15-ml Berlin Heart EXCOR® blood pump effectively supports pediatric patients with end-stage heart failure. This device fills a critical size gap, showing 100% survival in early trials.

Area of Science:

  • Pediatric Cardiology
  • Mechanical Circulatory Support
  • Biomedical Engineering

Background:

  • The Berlin Heart EXCOR® (EXCOR) is a widely used ventricular assist device for pediatric end-stage heart failure.
  • A size gap existed between the 10 ml and 25 ml EXCOR pumps, limiting options for patients with body surface area (BSA) of 0.33–0.5 m².

Purpose of the Study:

  • To evaluate the clinical experience and safety of the new EXCOR 15-ml blood pump.
  • To assess the device's suitability for pediatric patients within a specific BSA range.

Main Methods:

  • Early product surveillance (EPS) of 20 pediatric patients (mean age 1.6 years, mean BSA 0.45 m²) approved by CE and FDA.
  • Prospective data collection from high-volume pediatric transplant centers for 60 days post-implantation.

Main Results:

  • 100% survival rate at the end of the 60-day EPS period.
  • Mean support time was 43 days; 7 patients received heart transplants, 2 were weaned, and 11 remained on support.
  • Adverse events included cannula exit site infections (3 patients) and minor thromboembolic strokes with full recovery (2 patients).

Conclusions:

  • The EXCOR 15-ml blood pump provides optimal ventricular assist device support for children with BSA between 0.33 and 0.5 m².
  • The device effectively addresses a critical need in pediatric mechanical circulatory support.
