Background: Takotsubo syndrome (TTS) is a form of transient left ventricular (LV) dysfunction that usually resolves within days to weeks.
Objectives: We aimed to assess the predictors and prognostic impact of time-to-LV recovery after TTS.
Methods: Prospective serial imaging data from the nationwide, multicenter RETAKO (REgistry on TAKOtsubo Syndrome) were comprehensively reviewed to assess the timing of LV recovery.
