Files in this Data Supplement:

• Movie I - (AVI) (515 KB) Steady-state free-precession MRI image in a sagittal oblique view. Cine loop centered at the level of the DKS connection. Note an anterior aorta arising from a hypoplastic right ventricle that, in its turn, connects to a dominant left ventricle through a non-restrictive ventricular septal defect. The aorta and the main pulmonary artery are anastomosed distal to the semilunar cusps.
• Movie II - (AVI) (119 KB) Steady-state free-precession MRI images in a sagittal oblique view. All slices display images of the sagittal oblique view. The Fontan connection (right atrium to pulmonary artery) can be appreciated in the first clip (left upper corner), as well as the sluggish blood flow typical of this type of circulation. In the last clip (right lower corner), a diastolic spin dephasing up stream of the pulmonary valve can be noted, consistent with pulmonary insufficiency.
• Movie III - (MPEG) (155 KB) Modified parasternal long axis view of the 2 D-echocardiogram showing the connection between the aorta (anterior) and the pulmonary artery (posterior).
• Movie IV - (MPEG) (134 KB) Two-D color coded Doppler echocardiography (modified parasternal long axis view). There is systolic flow to both great arteries from the dominant left ventricle (through a non restrictive VSD in the case of the aorta) and mild pulmonary regurgitation.
• Movie V - (AVI) (845 KB) Three D volume rendered CT image showing both great arteries connecting through the DKS. Note the presence of a stent in the proximal descending aorta, at the level of the repaired coarctation.
• Movie VI - (MPEG) (704 KB) Retrograde position of a pigtail catheter in the subaortic right ventricle. The ventricular angiogram illustrates both ventricles and great arteries committed to the systemic circulation through the VSD and DKS.
