Table 3 Left atrial function in Takotsubo syndrome patients with typical and atypical ballooning

From: Transient left atrial dysfunction is a feature of Takotsubo syndrome

Variable Typical ballooning (n = 82) Atypical ballooning (n = 42) p
Total LA-EF (global function; reservoir) 42 (33–51) 49 (36–56) 0.14
Passive LA-EF (conduit)a 19 (14–29) 23 (15–31) 0.30
Active LA-EF (booster pump)a 29 (20–38) 30 (21–38) 0.59
  1. Values are median (IQR)
  2. EF emptying fraction, LA left atrial
  3. aPatients with atrial fibrillation during CMR imaging (n = 8) were excluded from this analysis, resulting in 74 patients with typical ballooning and 42 patients with an atypical ballooning pattern
