There is atrioventricular and ventriculoarterial discordance. The morphologic right ventricle which is on the left side is hypertrabeculated with top normal wall thickness. The left atrium is located on the left side. The morphologic left ventricle which is on the right side is normal in size and wall thickness. The right atrium is located on the right side. The aorta, which comes from the morphologic right ventricle, is anterior and to the left of the main pulmonary artery, which comes from the morphologic left ventricle. The single arch and descending thoracic segment of the aorta are left-sided. The aortic arch gives off three main branches without aberrant vessels. No evidence of coarctation or abnormal dilatation is identified. There are two superior and two inferior pulmonary veins draining into the left atrium. The inferior vena cava and a single right-sided superior vena cava drain into the right atrium.
