Biventricular conversion after Fontan circulation is feasible, improving ventricular function. However, outcomes are poorer for patients with failing Fontan physiology compared to elective cases.

Area of Science:

Cardiovascular Surgery
Pediatric Cardiology
Congenital Heart Disease

Background:

The Fontan circulation is a palliative procedure for single-ventricle physiology.
Takedown of Fontan circulation and conversion to biventricular physiology is a complex procedure.
Failing Fontan physiology necessitates alternative treatment strategies.

Purpose of the Study:

To evaluate the feasibility and outcomes of biventricular conversion after Fontan circulation.
To assess the impact of biventricular conversion on ventricular function.
To compare outcomes between failing Fontan physiology and elective takedown.

Main Methods:

Retrospective analysis of 23 patients undergoing Fontan takedown and biventricular conversion (2007-2020).

Keywords:

Fontan biventricular conversion congenital heart defect failing Fontan ventricular recruitment

Definition of failing Fontan physiology: pressure >15 mm Hg and/or complications.

Inclusion of staged ventricular recruitment in a subset of patients.

Main Results:

Biventricular conversion significantly increased indexed end-diastolic volume, end-systolic volume, and ventricular mass of the nondominant ventricle.
Overall mortality was 22%, with 4% early death.
Two-year survival for failing Fontan was 72.7%, versus 100% for elective takedown. Predictors of mortality included left dominant atrioventricular canal defect and early era of surgery.

Conclusions:

Biventricular conversion, primary or staged, is feasible for patients with prior Fontan procedures.
It offers an alternative to transplantation for failing Fontan physiology.
Outcomes are less favorable in failing Fontan cases compared to elective takedowns; optimal timing requires further study.
