Insights
The Fontan procedure offers palliative care for complex congenital heart defects when biventricular repair is not possible. However, evidence suggests its palliative nature does not support expanding its use in pediatric cardiac surgery.
Area of Science:
- Pediatric Cardiac Surgery
- Congenital Heart Disease
- Palliative Care
Background:
- The Fontan procedure is increasingly used for complex congenital heart lesions due to a lack of alternative biventricular repair options.
- Despite its expanding role, the Fontan procedure is recognized as a palliative measure, not a definitive cure.
Purpose of the Study:
- To address the controversy surrounding the expanding indications for the Fontan procedure.
- To review the current status of treating hypoplastic left heart syndrome, transposition of the great arteries, and tetralogy of Fallot.
Main Methods:
- Review of medium- and long-term results of the Fontan operation.
- Analysis of treatment strategies for specific complex congenital heart defects.
Main Results:
- Medium- and long-term outcomes confirm the palliative nature of the Fontan procedure.
- Current evidence does not support broadening the indications for the Fontan procedure.
Conclusions:
- The Fontan procedure remains a palliative option for specific complex congenital heart conditions.
- Careful consideration and evidence-based criteria are essential when determining the indications for the Fontan procedure in pediatric cardiac surgery.
Abstract:
Although there is fair agreement in many areas of pediatric cardiac surgery, issues of controversy and uncertainty persist. The role of the Fontan procedure in the treatment of complex congenital heart lesions is expanding, mainly by necessity, because an alternative biventricular repair is often not available. Reports on medium- and long-term results after Fontan's operation clearly demonstrate the palliative nature of the procedure, even in good candidates, and do not seem to support the widening of its indications. The purpose of this paper is to highlight this controversy, as well as to report on the state of affairs in the treatment of hypoplastic left heart syndrome, transposition of the great arteries, and tetralogy of Fallot.
