The first indication suggesting agenesis during examination
relates to image acquisition in nonstandard positions due to
abnormal cardiac positioning (Figures 2A and 2B). In the long
parasternal plane, the apex deviates posteriorly, revealing
a large segment of the RV, creating an impression of cavity
enlargement7,27 (Figures and Videos 1 and 2). The acquisition
of the apical 4-chamber plane will occur beyond or in the
posterior midclavicular line, different from the commonly
located in the 5th intercostal space, in the mid-midclavicular
line.
