Figure 57. Selected video frames from the parasternal long-axis (A) and subcostal (B) views of another patient with double-outlet right
ventricle and transposed great arteries (Taussig-Bing), demonstrating the origin of both the aorta (Ao) and the pulmonary artery (PA)
from the right ventricle (RV). An extremely large ventricular septal defect (VSD) is also shown. Reproduced from Ref. [39] . LA: Left
atrium; LV: left ventricle; SAT: subaortic tissue.

Figure 58. Selected video frames from apical four-chamber views of a patient with double inlet left ventricle (DILV) with closed (A) and
open (B) atrioventricular valves (arrows) during ventricular systole and diastole, respectively. The outlet chamber is not visualized in
this view (see Figure 59). Reproduced from Ref. [39] . LA: Left atrium; RA: right atrium.

Figure 59. Selected video frames from the parasternal long-axis (A) and modified apical (B, C) views of the same patient as is shown in
[Figure 58], demonstrating transposition of the great arteries (A) with the aorta (Ao) anteriorly and pulmonary artery (PA) posteriorly.
The connection of the right ventricle (RV) (outlet chamber) with the main chamber by a bulbo-ventricular foramen (BVF) is shown in
the (B). This chamber gives rise to the aorta (Ao), as seen in the (B). The origin of the PA from the main chamber [double-inlet left
ventricle (DILV)] is shown in the (C). Note the turbulent flow in the PA (C), suggesting stenosis. Continuous wave Doppler across this
region (not shown) revealed high velocity suggestive of significant pulmonary stenosis. Reproduced from Ref. [39] .
