Figure 23. Selected video frames from parasternal long-axis views of a patient with tricuspid atresia with normally related great arteries demonstrating enlarged left atrium (LA) and left ventricle (LV), a small right ventricle (RV), and a moderate-sized ventricular septal defect (VSD; thick arrow) on 2D (A) and color flow (B) imaging. Turbulent flow (B) with a Doppler flow velocity of 2.91 m/s by continuous wave Doppler (C) suggests some restriction of the VSD. Reproduced from Ref.^[19]. Ao: Aorta; PA: pulmonary artery.
