Heart transplant in a paediatric patient with restrictive cardiomyopathy on biventricular assist device support

Area of Science:

• Pediatric Cardiology
• Cardiovascular Surgery
• Medical Device Technology

Background:

• Severe restrictive cardiomyopathy presents significant challenges in pediatric patients.
• Biventricular assist devices (BiVADs) offer a potential bridge-to-transplant solution for end-stage heart failure.
• The Berlin Heart EXCOR is a recognized mechanical circulatory support system for pediatric use.

Purpose of the Study:

• To describe the use of the Berlin Heart EXCOR as a bridge-to-transplant in a pediatric patient with severe restrictive cardiomyopathy.
• To detail the management and successful orthotopic heart transplantation following mechanical support.
• To highlight the role of mechanical circulatory support in pediatric heart failure management.

Main Methods:

• A six-year-old girl with severe restrictive cardiomyopathy was supported with the Berlin Heart EXCOR biventricular assist device.
• The device served as a bridge-to-transplant, allowing for recovery of end-organ function.
• An orthotopic heart transplant was performed, involving explantation of the EXCOR device and implantation of the donor heart.

Main Results:

• The Berlin Heart EXCOR provided effective hemodynamic support, enabling patient stabilization.
• Full recovery of stable end-organ function was achieved prior to transplantation.
• The orthotopic heart transplant was successfully performed with the donor heart beating upon reperfusion.

Conclusions:

• The Berlin Heart EXCOR is a viable bridge-to-transplant option for pediatric patients with severe restrictive cardiomyopathy.
• Successful heart transplantation is achievable after mechanical circulatory support with the EXCOR device.
• This case underscores the importance of mechanical support in managing pediatric end-stage heart failure and facilitating transplant outcomes.
