Recently, some adults with functionally univentricular hearts were potential candidates for a Fontan completion. Objective: To review the early results of the single stage Fontan procedure in three adult patients in the last two years. Case Report: There was no mortality. Re-operations were observed in two patients. The mean extubation time, ICU stay, and hospital stay were three days, five days, and ten days, respectively. The median post-operative oxygenation was 95%. The NYHA class improved significantly in all patients. Conclusion: Single stage Fontan completion can be performed in carefully selected adult patients. The present report is the early results in three consecutive patients over the last two years. The long-term outcome needs to be followed. The authors hope to enroll more adult patients with univentricular heart and to determine the criteria for a potential adult candidate in the future.Mahidol UniversityMedicineReviewSCOPUS10.35755/jmedassocthai.2021.06.11888
