While operative survival has improved, pleural effusions remain a common postoperative complication, increasing morbidity and hospitalization. Our aim was to investigate the incidence and risk factors for unplanned readmissions due to post-Fontan pleural effusion.MethodsA retrospective review of all single ventricle patients who underwent the Fontan procedure from 2012-2023 was performed. This case-control study compared post-Fontan patients readmitted to the hospital due to pleural effusion with those who were not. Readmission was defined as rehospitalization for recurrent pleural effusion requiring intravenous diuretics and/or chest tube placement. Demographics, baseline clinical features, pre-Fontan hemodynamics, type of Fontan surgery, presence of fenestration, cardiac medications and doses, perioperative and post-discharge factors were analyzed between groups.ResultsSixty-one patients who were 42 ± 12.4 months of age underwent the Fontan operation.
