Fontan fenestration allows right-to-left shunting increasing cardiac output and oxygen delivery. Increased shunting occurs as cardiac function and ventricular end-diastolic pressures improve, potentially decreasing oxygen saturation. Complete closure may result in impaired Fontan haemodynamics and low cardiac output; however, there are no dedicated devices to reduce fenestration size. We describe Fontan fenestration size reduction using the Atrial Flow Regulator.
法桐开窗术可使右向左分流增加心输出量和氧输送。随着心功能和心室舒张末期压的改善，分流增加，氧饱和度可能降低。完全关闭可能导致法桐血流动力学受损和心输出量降低;然而，没有专门的设备来减小开窗的大小。我们使用心房流量调节器来减小法桐开窗的大小。
