Modified Fontan procedure for complex congenital heart disease

Area of Science:

• Cardiology
• Pediatric Surgery
• Congenital Heart Disease

Background:

• The Fontan procedure is a critical intervention for complex congenital heart disease.
• High postoperative morbidity and mortality remain significant challenges.
• This study reviews outcomes of the Fontan procedure performed over a decade.

Purpose of the Study:

• To evaluate the efficacy and outcomes of the Fontan procedure in a cohort of pediatric patients.
• To analyze the hospital mortality and long-term functional status of patients undergoing the procedure.
• To identify factors influencing outcomes in complex congenital heart disease repair.

Main Methods:

• Retrospective review of 35 consecutive patients undergoing the Fontan procedure between January 1980 and June 1991.
• Analysis of patient demographics, underlying cardiac conditions, surgical techniques (conduit type, anastomosis), and postoperative outcomes.
• Long-term follow-up of survivors to assess functional class (New York Heart Association) and need for reoperation.

Main Results:

• Overall hospital mortality was 23%, with a reduction to 11% in the final year of the study.
• The majority of patients (all but two survivors) achieved New York Heart Association functional class I or II postoperatively.
• Three patients required reoperation for complications such as atrioventricular valve regurgitation and conduit stenosis, with positive outcomes.

Conclusions:

• The Fontan procedure is a viable palliative option for complex congenital heart disease.
• Despite initial high mortality, outcomes demonstrated improvement over time and good functional recovery in survivors.
• Careful patient selection and surgical technique are crucial for optimizing results in Fontan palliation.
