Figure 9: This is a 3DE color flow, ECG-triggered (full volume) acquisition demonstrating a right sided Blalock-Taussig shunt (BTS). The grayscale image has been suppressed, thus providing an echocardiographic angiogram. The shunt is seen in its entirety from its origin from the innominate artery (Inn) to its insertion. The proximal and distal right pulmonary artery (pRPA and dRPA respectively) are well seen. Note the proximity of the superior vena cava (SVC) to the cranial end of the shunt. This dataset can be rotated, tilted and examined in an infi nite number of planes in order to delineate the location of stenosis. I, inferior; L, left
