Apical 3-Chamber (A3C) View - Regional Wall Anatomy on POCUS Echocardiogram Often one of the most challenging views to understand, the apical 4-chamber should be non-foreshortened and exclude the left ventricular outflow tract. In this perspective, the basal septum is shown (subdivided) and opposing wall is antero-lateral (subdivided again), along with the apical cap.
