Catheter-Based Fontan Completion Without Prior Surgical Preparation: Is This the Way Forward?

We report 3 cases of transcatheter Fontan completion in conventional Glenn anastomosis patients without surgical preparation by creating a tunnel between the pulmonary artery and right atrium. Cavocaval anastomosis is established by placing a covered stent graft within the scaffold created with the uncovered stents at the pulmonary artery-right atrium and inferior vena cava-right atrium junction.
