Deep recessus of the right ventricle. No ventricular septum defect found. Moderate hyprtrophy of the right ventricle. No Coarcatio aortae. Dilation of the transposed aorta.
Difference in size in the pulmonal-valve-pockets with a mega-pocket dorsally and two hypoplastic pockets ventrally. Correct exit of the pulmonory arteries. Correctly entering pulmonary veins.
