Transcatheter Fontan fenestration is a valuable option in situations of prolonged pleural drainage or low cardiac output in patients with failing Fontan circulation. This procedure relies on controlled baffle perforation without separation of the Fontan circuit from the pulmonary venous atrium, and placement of an accurately sized covered stent. We report a novel technique for transcatheter extracardiac Fontan fenestration using the SafeSept transseptal guidewire® and snare-controlled diabolo-shaped covered stent placement.
