TGA after atrial switch operation with Mustard procedure.
A: The aorta (AO) is positioned anteriorly and arises from the hypertrophied, morphologically RV. The pulmonary artery (PA) is positioned posteriorly and arises from the LV, which is smaller and has less myocardial mass. The septum (*) is pertrudes into the LV due to increased RV pressure.
B: Baffle view in TGA after Mustard procedure with a baffle from the SVC and IVC to the mitral valve (MV), with the superior (+) and inferior (*) baffle.
C: In plane flow map of the same view.
