Transcatheter fenestration dilation and/or creation in postoperative Fontan patients.

There are very few therapeutic options for severely symptomatic Fontan patients after spontaneous complete or virtual fenestration closure. Its reopening in 14 such patients led to dramatic hemodynamic improvement in most. The clinical experience with transcatheter fenestration creation and/or dilation in symptomatic Fontan patients is reported demonstrating feasibility, safety, and a novel management option for these patients.
