Fig 1.
DORV with subaortic VSD in a male aged 9 months.
(a) The aorta (Ao) was posterior and to the right of the main pulmonary artery (MPA) (the measured angle = 24°). (b) The VSD was situated below the aortic valve. (c) A ductus arteriosus (arrow) extended from the aortic arch to the MPA. LPA, left pulmonary artery; LV, left ventricle; RAA, right auricular appendage; RPA, right pulmonary artery; RV, right ventricle; PDA, Patent ductus arteriosus.
Fig 2.
DORV with subaortic VSD in a female aged 6 years.
(a) The aorta (Ao) was anterior and to the left of the main pulmonary artery (MPA) (the measured angle = 241°). (b) The VSD was situated below the aortic valve. (c) The volume rendering (VP) image showed the left pulmonary artery (LPA) stenosis (arrow) and the persistent left superior vena cava (star), as shown in Fig 2a. LAA, left auricular appendage; LV, left ventricle; RPA, right pulmonary artery; RV, right ventricle.
Fig 3.
DORV with subpulmonary VSD in a female aged 3 years.
(a) The aorta (Ao) was anterior and to the right of the main pulmonary artery (MPA) (the measured angle = 120°). (b) The VSD was situated below the pulmonary valve. (c) The volume rendering (VP) image showed the total anomalous pulmonary venous connection of the intracardiac type with 4 pulmonary veins (arrows) draining to the coronary sinus. LPA, left pulmonary artery; LV, left ventricle; RPA, right pulmonary artery; RV, right ventricle.
Fig 4.
DORV with double-committed VSD in a female aged 3 months.
(a) The two great arteries were side-by-side (the measured angle = 90°). (b) The VSD was situated below both the two arterial valves. (c) The volume rendering (VP) image showed the coarctation of the aorta (arrow) with poststenotic dilatation. Ao, aorta; LA, left atrium; MPA, main pulmonary artery; RA, right atrium; RPA, right pulmonary artery.
Fig 5.
DORV with noncommitted VSD in a female aged 7 years.
(a) The aorta (Ao) was anterior and to the right of the main pulmonary artery (MPA) (the measured angle = 167°). (b) The VSD (arrow) is far from both the two arterial valves. (c) The volume rendering (VP) image showed the dysplasia of the left anterior descending artery (LAD) and anomalous course of the left circumflex artery (LCX) crossing anterior of the left auricular appendage (LAA). LA, left atrium; LPA, left pulmonary artery; LV, left ventricle; MPA, main pulmonary artery; RPA, right pulmonary artery; RV, right ventricle.
