The fenestration in Fontan operation consists in creation of a communication between venous circulation and the pulmonary venous atrium, allowing direct passage of blood from the venous to the systemic circulation (right-to-left shunt). There is no general agreement concerning the mean pulmonary artery pressure (mPAP) level above which fenestration is indicated. There are no strict guidelines for the indications for fenestration closure as well. Here we present our data about invasive hemodynamic assessment before and after temporary closure of the fenestration in patients after Fontan operation. Our recommendations regarding comprehensive evaluation of patients with fenestrations after Fontan surgery are also presented.
