Figure 54. Selected video frames from apical four chamber views of six different babies with hypoplastic left heart syndrome, demonstrating varying degrees of left ventricular (LV) hypoplasia, starting from slit-like LV in (A) (arrow), and progressively larger LVs in (B-F). All of them require Norwood palliation. Other features shown are a small left atrium (LA), large right atrium (RA), and large right ventricle (RV). Reproduced from Ref.[36].
