Figure Legends:
Figure 1 Electrocardiogram on arrival shows sinus tachycardia, with
inferior Q waves, poor R wave progression and non-specific ST-segment
changes
Figure 2a) Coronary angiogram showing a right dominant circulation
without any obstructive disease noted in the right coronary artery 2b)
Antero-posterior cranial view showing bifurcation of left main into left
anterior descending and circumflex arteries without any obstructive
coronary artery disease noted throughout the length of left anterior
descending artery 2c) Antero-posterior caudal view showing absence of
obstructive coronary artery disease in the circumflex territory 2d) Left
ventriculogram showing severe hypokinesis of the apical segments with
apical ballooning and basal hyperkinesis, changes consistent with
classical Takotsubo cardiomyopathy.
Figure 3 Electrocardiogram on arrival shows sinus rhythm symmetric deep
T wave inversions in the precordial leads and inferior ST changes
Figure 4a) Coronary angiogram showing a right dominant circulation
without any significant disease in the right coronary artery 4b)
Antero-posterior cranial view showing a myocardial bridge in the
mid-left anterior descending artery without any obstructive coronary
artery disease 4c) Left anterior oblique cranial view showing
bifurcation of the left main in left anterior descending and circumflex
arteries, with no significant obstructive disease noted in the
circumflex distribution 4d) Left ventriculogram showing severe
hypokinesis of the apical segments with apical ballooning and basal
hyperkinesis during systole, changes consistent with classical Takotsubo
cardiomyopathy
Supplementary Video 1 Parasternal long-axis view of the echocardiogram
for the second case shows preserved basal wall motion and apical
hypokinesis.
Supplementary Video 2 Apical three-chamber view of the echocardiogram
for the second case confirms apical and mid-apical antero-septal
hypokinesis.
