AbstractBetween 1994 and 2011, we performed 133 Fontan conversions with arrhythmia surgery. Most patients had tricuspid atresia or double-inlet left ventricle with prior atriopulmonary connection. Operative mortality was 1.5%, and mean length of stay was 14 days. A total of eight patients (6%) have had late cardiac transplantation. Freedom from arrhythmia recurrence is 85% at 10 years. For properly selected patients with a functionally univentricular heart who have had an atriopulmonary Fontan procedure, Fontan conversion with arrhythmia surgery significantly improves quality of life.

The portrayal of a beautiful youngster performing uninhibited acrobatics based on Fontan physiology, as presented by Marshall Jacobs, is a brilliant and beautiful thing for us to see. It is, perhaps, all about will over physiology. But it is, nevertheless, happening for that child. Marshall mentioned the need for re-transplantation, whether the beginning strategy was transplantation or reconstructive surgery. Indeed, a relatively small percentage of children transplanted will require re-transplantation because of severe graft coronary disease. Remarkably, in the Loma Linda experience, 10-year actuarial survival for 26 patients following elective re-transplantation is over 85%, exceeding overall actuarial survival at 10 years for children following primary transplantation. Many of the transplanted infants, however, seem to be realistically hopeful that one heart will last their entire lifetime. Of course, the hope is that their's will be a long and healthy lifetime. The requirement for late transplantation following Fontan procedures, however, seems almost inevitable. We'll simply have to keep these children with Fontan circulation under surveillance to see when, in the course of their lives, transplantation will become necessary. Unfortunately, operative and long-term survival among children who are transplanted for failing Fontan physiology have, as yet, been somewhat suboptimal.

Hypothesis: Biventricular conversion (BiVC) following takedown of Fontan circulation is feasible and results in improved hemodynamics. Methods: Retrospective analysis of patients who had takedown of Fontan circulation and conversion to BiV circulation at a single center from September 2007 to April 2020. Failing Fontan physiology was defined as Fontan circulation pressure >15 mmHg. Results: There were 23 patients (median age: 10.0 (7.5-13.0) years); 15 (65%) had failing Fontan physiology and 8 (35%) underwent elective takedown of their Fontan circulation. Of the 15 patients with failing Fontan physiology, 4 had exercise intolerance or cyanosis, 3 had hepatic congestion or cirrhosis, 3 had end-organ damage and 1 patient had protein losing enteropathy; the rest 4 patients had no other sign of SVP complications. A subset of patients (n=6) underwent recruitment of the non-dominant ventricle prior to conversion. HLHS (p<0.01) and sub-/aortic stenosis (p<0.01) were more common in these patients. BiVC with or without staged ventricular recruitment led to a significant increase in indexed end-diastolic volume (p<0.01), indexed end-systolic volume (p<0.01) and ventricular mass (p<0.01) of the non-dominant ventricle (14 RV, 9 LV). There were 1 (4%) early and 4 (17%) late deaths. All who underwent elective BiVC survived, while 2-year survival rate for patients with a failing Fontan circulation was 72.7% (95% CI: 37-90%) (Figure 1). The overall, 1-year reintervention free survival was 44.1% (95% CI: 21-65%). Left dominant atrioventricular canal defect (p<0.01) and early year of BiVC (p=0.02) were significant predictors for mortality. Conclusions: BiVC is feasible in patients with failing Fontans, and has promising outcomes after elective takedown of Fontan circulation. A staged approach for ventricular recruitment does not seem inferior to primary BiVC. The optimal timing for BiVC in Fontan patients needs further evaluation.
