A novel and simple cardiac magnetic resonance score (PERT) predicts outcome in takotsubo syndrome.

Objectives: To find simple imaging-based features on cardiac magnetic resonance (CMR) that are associated with major adverse cardiovascular events (MACE) in takotsubo syndrome (TTS).

Methods: Patients with TTS referred for CMR between 2007 and 2021 were retrospectively evaluated. Besides standard CMR analysis, commonly known complications of TTS based on expert knowledge were assessed and summarised via a newly developed PERT score (one point each for pleural effusion, pericardial effusion, right ventricular involvement, and ventricular thrombus).
