Patients with severe right ventricular outflow tract obstruction in tetralogy of Fallot typically have right-to-left shunting, resulting in low pulmonary blood flow and cyanosis. Here we present the case of an infant with tetralogy of Fallot and severe pulmonary valve stenosis, complicated by systemic hypertension, the presence of which altered flow dynamics and possibly prevented cyanosis.
