ABSTRACT
Fenestration in the modified Fontan operation allows right-to-left shunting, which reduces the Fontan pathway pressure and improves cardiac output. However, on account of the fact that persistent right-to-left shunting results in cyanosis and paradoxical emboli, fenestration closure is recommended after recovery from the Fontan operation. This study recruited 3 patients who underwent the transcatheter closure of the Fontan fenestration with the ASD-Amplatzer because of severe cyanosis and significant intracardiac shunts. Fenestration closure was performed at a mean age of 8 yr [6-12 yr] and average of 15 months after the Fontan operation. Aortic O[2] saturation increased by an average of 17.6% [9-26%]. During more than a two-year period of follow-up [mean 27 months], two patients had complete occlusion on echocardiography and the other one had a small residual shunt. One of these patients had atrial flutter during the follow-up. The transcatheter closure of the Fontan fenestration is a safe and feasible technique that is effective in elevating systemic O[2] saturation and well-being and confers acceptable growth and development in children
