An Extensive Review on Imaging Diagnosis Methods in Takotsubo Syndrome

Figures

• 

  Fig. 1.. Coronary angiography in a 53 year-old female patient with Takotsubo Syndrome. Non-obstructive epicardial coronary arteries - images (A) and (B). Ventriculography showing apical akinesia and basal hyperkinesia - images (C) and (D).

• 

  Fig. 2.. Transthoracic echocardiography images apical four-chambers views of a 73 year-old female patient with Takotsubo Syndrome. Apical akinesia in the acute phase (A and B) and normalized wall motion and ejection fraction at 1 month follow-up (C and D).

• 

  Fig. 3.. Transthoracic echocardiography images apical four-chambers views of a 73 year-old female patient with Takotsubo Syndrome showing the evolution of diastolic function. E wave velocity progressed from 40 cm/s in the acute phase to 70 cm/s at one month follow-up, the E/A ratio from 0.5 to 0.8 (A and B). Lateral e’ velocity increased from 4 cm/s to 8 cm/s and E/e’ ratio from 10 to 8.7 (C and D). 2D, two dimensional; PW, pulsed wave doppler; TDI, tissue doppler imaging.

  Fig. 4.. Speckle tracking echocardiography showing the improvement in global longitudinal strain and time to peak longitudinal strain from the acute phase (A) to 1 month follow-up (B). GLS, global longitudinal strain.

• 

  Fig. 5.. Cardiac Magnetic Resonance Imaging of a 78 years old female patient in the acute phase of Takotsubo Syndrome. Myocardial edema can be observed in the apical regions of the left ventricle in T2 weighted images (A and B) and the lack of late gadolinium enhancement in C and D.
