DILV with TGA case 1

Asymmetrical 4 chamber view.
The right ventricle is smaller than the left ventricle.
The left-sided ventricle can be determined as morphological left, because the papillary muscles attach to the free wall of the ventricle.
Note that the atrial septum, including the crux is not in alignment with the ventricle septum.
Large VSD.

Apical insonation.
The right ventricle is visualised better and is much smaller than the left ventricle.
Large VSD.
Atrial septum and ventricle septum are not in alignment.
Mitral valve appears normal.
The tricuspid valve is overriding the VSD and opens partly in the left ventricle (thus: double inlet left ventricle).
The left ventricle outflow tract is visible as well, a bit larger than normal, and has an normal attachment to the ventricle septum.
At the end of the clip is, however visible that this outflow tract shows lateral branching, thus identified as the pulmonary trunk!
Right ventricle outflow tract, which arises anteriorly from the heart.
Lateral branching is absent and the course of the vessel resembles an aortic arch.
The left ventricle outflow tract is shortly in this clip, with clear lateral branching, thus this vessel is identified als the aorta (running rightwards from the trachea).
