The fenestrated Fontan (FF) procedure is associated with better hemodynamics postoperatively than the modified Fontan procedure without a fenestration.

Although a fenestration improves cardiac output, there is a cost of right-to-left shunting, cyanosis, and the subsequent risk of thromboembolism.
Our goal was to evaluate our experience with FF procedures. Specifically, we sought (1) to assess the outcomes of closed fenestrations, (2) to determine the rate of spontaneously closed fenestrations, and (3), among patients with patent fenestrations, to determine whether a clinical or laboratory variable could be used to predict their outcomes.
After institutional review board approval, 23 FF procedures with no other source of significant right-to-left shunt were identified. The cardiac lesion in the majority of patients (16/23 [70%]) was hypoplastic left heart syndrome.
Pre-Fontan Catheterization Hemodynamics
The average mean pulmonary artery pressure was 11 ± 2.8 mm Hg. The mean pulmonary vascular resistance (PVR) was 2.3 ± 1.5 indexed Wood units. The mean systemic ventricular end-diastolic pressure was 7.8 ± 2.6 mm Hg.
