Abstrakt: Since the first description of takotsubo syndrome 30 years ago, only a little is known on the underlying physiopathology leading to peculiar left ventricular function alteration and myocardial damage related to acute emotional or physical stress. In the present case, we used continuous invasive thermodilution to evaluate coronary microvascular function at the acute phase of takotsubo and after recovery. The acute phase of takotsubo was characterized by a reduced coronary output and altered reserved flow with persistently high resistance during hyperaemia. At 6 weeks, we described a complete recovery of microvascular function, concomitant to LVEF recovery.
