Figure 66. Selected video frames from an apical four-chamber view of a baby with a complete form of atrioventricular septal defect with severely hypoplastic left ventricle (LV). Echo images in ventricular diastole (A) and systole (B) are shown; the LV hypoplasia is more obvious in (B). The left atrium (LA), right atrium (RA), and right ventricle (RV) are labeled.
