Embolization of Veno-venous Collaterals after the Fontan Operation Is Associated with Decreased Survival

After Fontan operation, hemodynamically significant veno-venous collateral (VVC) vessels can lead to systemic arterial desaturation. Outcomes after embolization of VVCs have not been determined. We sought to determine the frequency of and outcomes for patients undergoing VVCs embolization after Fontan operation.We retrospectively analyzed clinical and hemodynamic data of patients who underwent cardiac catheterization after the Fontan operation...
