  1. The number of patients (and percentage) with and without a shunt (as defined as less than 0.85 or greater than 1.19) is shown for patients with Tetrology of Fallot (ToF) and atrial level shunting (ASD/PAPVR). Qp is based on sum of branch pulmonary artery flow. SV = stroke volume. CO = cardiac output.
