Does atrial CMR-FT provide superior prognostic value for adverse events compared to LVEF and atrial volume in patients with Takotsubo syndrome?
Atrial CMR-FT identifies transient impairments in LA mechanics and may serve as a superior prognostic marker for adverse events in Takotsubo syndrome compared to traditional parameters like LVEF.
TTS pathophysiology comprises transient impairments in LA reservoir and conduit functions and enhanced bi-atrial active booster pump functions. Atrial CMR-FT may evolve as a superior marker of adverse events over and above established parameters such as LVEF and atrial volume.
Backhaus et al. (Sat,) studied this question.
