Figure 21. Selected video frames from apical four-chamber, 2-dimensional echocardiographic views of a patient with tricuspid atresia showing an enlarged left ventricle (LV), a small right ventricle (RV), and a dense band of echoes at the site where the tricuspid valve echo should be (ATV; thick arrow) with closed (A) and open (B) mitral valve during LV systole and diastole, respectively. A moderate-sized ventricular septal defect (VSD; thin arrow) is shown. Reproduced from Ref.^[19]. ATV: Atretic tricuspid valve; LA: left atrium; RA: right atrium.
