Echocardiogram after the placement of the modified Blalock-Taussig shunt (MBTS). (A) Color flow Doppler showing flow from the aorta (Ao) to the pulmonary artery (PA) through the MBTS. (B) Pulse wave Doppler demonstrating continuous antegrade flow through both systole (S) and diastole (D).

Echocardiogram after the placement of the right ventricle to pulmonary artery (PA) conduit. (A) Color flow Doppler showing antegrade flow from the right ventricle (RV) into the conduit. (B) Pulse wave Doppler interrogation of the right ventricle to pulmonary artery conduit demonstrating antegrade flow through the conduit only during systole (arrow). (RA = right atrium)
