The Fontan procedure: a historical review

Area of Science:

• Cardiovascular Surgery
• Pediatric Cardiology
• Congenital Heart Disease

Background:

• The Fontan operation, developed by Fontan and Baudet, involves complete bypass of the right ventricle.
• It was initially designed for patients with tricuspid atresia, a severe congenital heart defect.
• This procedure builds upon the principles of the earlier Glenn partial right heart bypass.

Discussion:

• The Fontan operation effectively eliminates the need for the right ventricle in single-ventricle physiology.
• By bypassing the right ventricle, it prevents ventricular volume overload and pulmonary hypertension.
• This surgical technique is applicable to various forms of univentricular heart disease.

Key Insights:

• Successful implementation of complete right ventricle bypass marks a significant surgical milestone.
• Elimination of shunts is crucial for preventing hemodynamic complications.
• The Fontan procedure represents a historic advance in surgical management of complex congenital heart conditions.

Outlook:

• Continued refinement of the Fontan operation may further improve long-term outcomes.
• Research into alternative surgical strategies for univentricular hearts remains ongoing.
• Understanding the long-term implications of single-ventricle palliation is essential for patient care.
