Fig. 3 Transthoracic echocardiograms (4-chamber view), obtained 15 days after onset of takotsubo syndrome. A) Baseline image. The associated video shows moderate improvement of right and left ventricular dysfunction with respect to its state at admission (see Fig. 2). B) Image obtained after intracoronary acetylcholine infusion (100 μg in the left coronary artery). In the associated video, mild worsening of the dysfunction detected at baseline is apparent. C) Image obtained after intracoronary nitroglycerin infusion. The associated video shows definite improvement in ventricular function.
