From: Transient left atrial dysfunction is a feature of Takotsubo syndrome
Measurement of left atrial volumes. LA area was tracked in 4-chamber (Panels a-c) and 2-chamber views (Panels d-f) for biplane assessment of LA volumes at ventricular end-systole (Panels a and d), immediately before atrial contraction (Panel b and e) as well as at ventricular end-diastole (Panels c and f). The example shows a TTS patient with typical apical ballooning (blue arrows)
