Takotsubo cardiomyopathy (TTC) is primarily regarded as a form of acute and transient myocardial disease with a variety of characteristic wall-motion abnormalities. Importantly, a significant portion of TTC cases generally present with variable degrees of acute left ventricular (LV) dysfunction with or without clinical HF. On the other hand, LV dysfunction in the setting of TTC has been universally and exclusively considered as a synonym for systolic dysfunction, potentially overlooking other forms of myocardial pathologies, including transient diastolic dysfunction, in this setting. More interestingly, recent observations suggest that TTC, despite its macroscopic recovery, may not always manifest as a fully reversible phenomenon, suggesting persistence of microscopic changes at the cellular level to some degree. In clinical practice, these residual changes might largely account for the evolution of certain pathologies, including persistent diastolic dysfunction and subclinical LV dysfunction with variable symptomatology (particularly those arising during high levels of myocardial workload, including exercise, etc.) among TTC survivors. Within this context, the present review aims to highlight various clinical patterns and implications of LV dysfunction in the setting of TTC, and to provide basic information regarding morphological and mechanistic characteristics of wall-motion abnormalities in this setting.
