The Fontan procedure, a complex heart surgery, can lead to late failure. This case study shows mechanical circulatory support successfully bridged a patient to cardiac transplantation.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease
- Cardiac Surgery
Background:
- The Fontan procedure is a palliative surgery for complex single ventricle congenital heart defects.
- Survivors face risks including ventricular dysfunction, plastic bronchitis, protein-losing enteropathy, and late cardiac failure.
- Late Fontan failure presents a significant clinical challenge, with cardiac transplantation as the only definitive treatment.
Observation:
- This report details an adolescent female with severe late cardiac failure post-Fontan conversion.
- The patient initially required extracorporeal life support (ECLS) for resuscitation.
- The patient was subsequently transitioned to a Berlin Heart EXCOR® ventricular assist device (VAD).
Findings:
- Successful bridging to cardiac transplantation was achieved using mechanical circulatory support.
- The combination of ECLS and VAD provided crucial hemodynamic support.
- The patient ultimately underwent successful heart transplantation.
Implications:
- Mechanical circulatory support offers a viable short-term solution for patients with late Fontan failure awaiting transplantation.
- This case highlights the importance of advanced support strategies in managing complex pediatric cardiac conditions.
- Successful transplantation offers a durable option for end-stage Fontan-associated cardiac dysfunction.
