Role of echocardiography in takotsubo cardiomyopathy.

Takotsubo cardiomyopathy (TTC) is characterized by transient and reversible left ventricular (LV) systolic dysfunction due to extended myocardial stunning. Despite a good long term prognosis, approximately one-third of patients with TTC experience life-threatening complications during the acute phase. Echocardiography is the first imaging modality for an early evaluation of LV systolic and diastolic function in patients with TTC. Moreover, echocardiography allows the detection of specific findings associated with TTC, such as LV outflow tract obstruction, mitral regurgitation, and right ventricular involvement, providing crucial information for clinical management and therapy and for monitoring myocardial function recovery during the follow-up.
