Fig 3. 20°-70° angle of the inflow and outflow tract planes.

Fig 3

One of the two outflow tracts is in closer proximity to both inflow tracts so that blood from both inflow tracts will enter this outflow tract, whereas the other outflow tract is only supplied by the one inflow tract it is closest to. The depicted heart has a discordant ventriculoarterial connection, meaning the pulmonary trunk is connected to the morphologically left ventricle and the aorta is connected to the morphologically right ventricle and communicates with the morphologically left ventricle via the ventricular septal defect. The angle in this specific heart was 45°.Ao: Aorta; AV: atrioventricular valve; PT: pulmonary trunk; VSD: ventricular septal defect; Ao = Aorta. Blue: deoxygenated blood, red: oxygenated blood, purple: mix of deoxygenated and oxygenated blood.
