Video 20.18 3D color Doppler flow mapping to demonstrate clinically important narrowing within the Blaylock – Taussig shunt
With the advent of 3D color Doppler flow mapping, a virtual angiogram can be created and can help to demonstrate clinically important narrowing within the Blaylock – Taussig shunt. This 3D image demonstrates a BT shunt as it enters the right pulmonary artery without suggestion of narrowing.
