Insights
The Fontan operation has evolved significantly since 1971. This case study reviews 40 years of interventions for single ventricle patients, highlighting the Fontan procedure and cardiac CT angiography for complex circulation evaluation.
Area of Science:
- Cardiology
- Pediatric Cardiac Surgery
- Medical Imaging
Background:
- The Fontan operation, first described in 1971, is a palliative surgical procedure for complex single-ventricle congenital heart defects.
- Over four decades, the Fontan operation has undergone numerous modifications and improvements to enhance patient outcomes.
Observation:
- This study details the comprehensive medical, surgical, and percutaneous interventions for a single ventricle patient over 40 years.
- The evolution of the Fontan procedure, including its indications, sequelae, and complications, is traced through this patient's case.
Findings:
- Cardiac computed tomography with angiography (CCTA) is presented as a valuable noninvasive tool for assessing the intricate Fontan circulation.
- The case illustrates the long-term management challenges and the importance of advanced imaging in Fontan patients.
Implications:
- Understanding the historical development and long-term sequelae of the Fontan operation is crucial for managing complex congenital heart disease.
- Noninvasive imaging modalities like CCTA play a vital role in the surveillance and management of patients with Fontan physiology.
Abstract:
The Fontan operation has gone through multiple incarnations since Fontan and Baudet's initial description in 1971. Through the medical dossier of a patient with a single ventricle, we plot the history of medical, surgical, and percutaneous interventions over the past 40 years, specifically focusing on the Fontan procedure, its development, indications, sequelae, and complications. Cardiac computed tomography with angiography is highlighted as a noninvasive imaging tool for the evaluation of the complex Fontan circulation.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
