Surgical reinterventions after modified Fontan operations

Area of Science:

• Pediatric Cardiac Surgery
• Congenital Heart Disease Management
• Cardiovascular Interventions

Background:

• Surgical reinterventions following Fontan operations are associated with significant mortality.
• This study reviews institutional experience with repeated operations after Fontan procedures.
• Assessing the efficacy of these reinterventions is crucial for improving outcomes.

Purpose of the Study:

• To summarize the experience with surgical reinterventions after Fontan operations.
• To evaluate the effectiveness and outcomes of these repeated surgical procedures.
• To identify factors influencing success in reoperations for Fontan patients.

Main Methods:

• A retrospective analysis of 162 Fontan modifications performed between 1983 and 1995.
• Identification and detailed review of 15 cases (9%) requiring repeated interventions.
• Categorization and assessment of the types of reinterventions performed and their outcomes.

Main Results:

• Reinterventions included procedures like atrioseptostomy, subaortic stenosis resection, and pericardectomy.
• Good outcomes were achieved in 40% of cases, with satisfactory results in 33%.
• A mortality rate of 27% was observed in patients undergoing repeated surgical interventions.

Conclusions:

• Repeated interventions to correct technical errors in Fontan operations are generally successful.
• Atrial septostomy demonstrates good results when anatomical issues like subaortic obstruction are absent.
• Careful patient selection and procedural planning are vital for optimizing outcomes in Fontan reoperations.
