From: Transient left atrial dysfunction is a feature of Takotsubo syndrome
Improvement of total left atrial emptying fraction in patients with Takotsubo syndrome. Shown is the total LA-EF during the acute/subacute phase as well as at follow-up in 20 patients with TTS. Each line represents an individual patient. The figure shows a significant improvement or constantly preserved LA function in 18 patients (black lines) while a slight deterioration was observed in two patients (red lines) despite recovery of LV function (ejection fraction 53 and 68%, respectively). *Patient with permanent atrial fibrillation. LA = left atrial; EF = emptying fraction
