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

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

Values are median (IQR)

EF emptying fraction, LA left atrial

^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
