title: Transcatheter repair of Fontan baffle stenosis and fenestration in two patients using Cook Zenith aortic endografts.
abstract: Patients with Fontan baffles for single ventricle may have cyanosis from right-to-left shunt through leaks in the baffle or due to intentionally created fenestrations. Typically this right-to-left shunt may be addressed with catheter-based occlusion devices. However, in narrowing of the Fontan baffle, placement of occluders within the Fontan baffle may additionally narrow the pathway and is therefore undesirable. We describe 2 patients with the combination of Fontan baffle stenosis and patent fenestration treated with a Zenith abdominal aortic aneurysm endograft (Cook Medical). The covered stent graft both occluded the right-to-left shunt and eliminated the baffle stenosis. Both patients have had symptomatic improvement.
