4. It is now 30 years since Japanese
investigators first described Takotsubo
Syndrome as a disorder occurring
mainly in ageing women, ascribing it to
the impact of multivessel coronary
artery spasm.

Broken Heart Syndrome
Takotsubo Syndrome
‘Broken heart syndrome’ is easy to remember and has more appeal for the general
community compared with the name ‘Takotsubo syndrome’.
Thus, it is a popular term used in the media for Takotsubo syndrome , but it is a misnomer.

*Without concurrent conditions; head injury/intracranial bleed/
pheochromocytoma/myocarditis/hypertrophic cardiomyopathy
In 2004, the Mayo Clinic group published their diagnostic criteria ,
which are still widely used today
Ann Intern Med 2004; 141: 858.
11. The definition of TS according to the two most recent position papers involves several diagnostic
criteria , most of which are common and include transient RWMAs of the LV and/or RV after a stressful
trigger (emotional, physical, or combined, neurologic disorders, or pheochromocytoma), RWMAs extend
beyond the distribution of a single coronary artery, new and reversible ECG abnormalities, elevated
serum NPs, and relatively small Tp elevation.

Importantly, InterTAK criteria describe that the presence of pheochromocytoma and significant CAD are not contradictory to the diagnosis of TTS.
The most widely used diagnostic
criteria are HFA/ESC diagnostic
criteria, which have revised the
earlier Mayo Clinic Criteria .
Recently, the InterTAK Diagnostic
Criteria have been proposed

Covidsubo ?????!!!!!

16. Takotsubo Rising During COVID-19?
Stress, Viral Triggers Need Attention
Stress or Virus?
What’s not clear is the extent to which the telltale
characteristics of Takotsubo are directly related to the viral
infection or are caused by stress secondary to the pandemic
and its economic and social effects.
The two distress situations
empower each other, the
COVID and Takotsubo.

If we have a patient who might be
more emotional, pay attention:
psychological support is very
important to them.
18. This figure draws attention to potential pathophysiological mechanisms for the observed reversible
myocardial dysfunction such as sympathetic overdrive-mediated multi-vessel epicardial spasms,
microvascular dysfunction, the direct toxicity of catecholamines, lipotoxicity, and inflammation.

25. Schematic representation of takotsubo cardiomyopathy. A takotsubo is a pot used to catch an octopus. A A takotsubo is
tied to a rope and submerged in the sea; it is retrieved after an octopus has entered the pot. B The shape of the
takotsubo resembles the configuration of the left ventricle during systole on imaging, such as left ventriculography.

26. White lesions are the territory of a transient abnormality in LV wall motion. Apical type which
is the so-called takotsubo is most frequent. Some of the other variations are reported such as
mid-ventricular, basal, and focal type. Journal of Nuclear Cardiology volume 26, pages1602–1616(2019
Variation of TS.
There are other variants of TS for which the prevalence is unknown. This may be because they are rare, or alternately,
they may be poorly recognised. These variants include: 1 right ventricular involvement. 2 apical tip sparing variant.
3 biventricular apical dysfunction. 4 isolated RV involvement 5 global dysfunction.
27. Four Types of Takotsubo
Cardiomyopathy.
Among the 1750 study patients, the most
common type of takotsubo (stress)
cardiomyopathy was the apical type
(in 81.7% of patients) (Panels A and B),
followed by the midventricular type (in 14.6%
of patients) (Panels C and D), the basal type (in
2.2% of patients) (Panels E and F), and the
focal type (in 1.5% of patients) (Panels G and
H).
All left ventricular angiograms were obtained in the
right anterior oblique view (30 degrees) during
diastole (left column) and systole (middle column).
In the far right column, the wall-motion
abnormality that was observed
with each type of the disorder is shown, with
red indicating diastole, white indicating
systole, and the dashed line indicating the
location of the wall-motion abnormality.

34. Because clinical presentation of TTS mimics ACS , the differential
diagnosis between the two syndromes is challenging.
To differentiate TS and ACS , the InterTAK Diagnostic Score has been proposed.
If 50 or more points were present, the specificity of TS was 95%.
If score was 31 or less, the specificity of ACS was also 95%.

49. Clinical progress after the first 48 hours generally includes
substantial recovery, as measured by resolution of regional LV
hypokinesis on echo , and also of hypotension.
However, most patients continue to feel lethargic for at least 3
months post onset of symptoms , and many complain of
exertional dyspnoea.
Recovering from takotsubo : Will it happen again?
Recurrence of TS is a relatively rare problem, with a risk of
approximately 1–2% per annum .
Most importantly, it has progressively emerged that the long-
term mortality risk after attacks of TS is similar to that after
acute MI , and that a substantial proportion of these deaths is
of cardiovascular origin.
50. TS can either be benign or a life-threating condition depending on the inciting stress factor.
Overall, TS patients had long-term outcomes comparable to age- and sex-matched ACS patients.
TS patients related to physical stress showed higher mortality rates than ACS patients during long-
term follow-up, whereas patients related to emotional stress had better outcomes compared with
ACS patients.

62. Dynamic left ventricular outflow tract obstruction in apical ballooning syndrome
(Takotsubo cardiomyopathy)
Abstract
Patients with apical ballooning syndrome may develop dynamic left ventricular
outflow obstruction due to systolic anterior motion of the mitral valve leaflet and
secondary functional mitral regurgitation, causing decreased cardiac output and
hypotension.
If suspected, bedside echocardiography will quickly confirm this complication.
Positive inotropic/chronotropic agents should be avoided as they may exacerbate
outflow tract obstruction, resulting in further hemodynamic compromise.

Am J of Cardiology 111,8,1232-1235,2013
In patients with TC, the motion of the basilar and middle segments of the RV free wall is
often hyperkinetic.
However, the motion of the apical segment of the RV free wall is usually hypokinetic,
in the same manner as LV apical motion .
Interestingly, this distinct imaging feature is exactly opposite the classic echo appearance in
patients with acute and massive pulmonary embolism, McConnell's sign, which is defined as
hyperkinesis of the RV apex and hypokinesis of the remaining segments of the RV free wall.

Echocardiography shows akinesia of apical or midventricular segments leading to systolic dysfunction. The normal basal segments become hypercontractile, giving a ballooned out appearance of the apical or mid-cavity segments [Figure 3]. Ballooning may lead to altered spatial relationships between mitral leaflets and subvalvular apparatus, which may result in MR and dynamic LVOTO causing SAM.
InterTAK Diagnostic Score was developed from the results for International Takotsubo Registry [Eur J Heart Fail. 2017;19(8):1036.] by the InterTAK International Registry Group. The score was developed for differentiating Takotsubo cardiomyopathy from acute coronary syndrome in the acute stage.
InterTAK Diagnostic Score estimates the probability for Takotsubo cardiomyopathy and was found to have high sensitivity and specificity for differentiating it from acute coronary syndrome. If 50 or more points were present, the specificity of Takotsubo cardiomyopathy was 95%. If score was 31 or less, the specificity of acute coronary syndrome was also 95%.
Importantly, the spectrum of different presentations of ACSs is indeed different between the sexes : women present more often with NSTEMI, more commonly have endothelial erosion rather than plaque rupture as the underlying cause, particularly among younger female smokers, and finally Takotsubo syndrome and spontaneous coronary dissection are typical female presentations of ACSs
Table summarises key aspects of the early and late clinical features and complications of TTS.
Conclusions
Overall, TTS patients had long-term outcomes comparable to age- and sex-matched ACS patients. Also, we demonstrated that TTS can either be benign or a life-threating condition depending on the inciting stress factor. We propose a new classification based on triggers, which can serve as a clinical tool to predict short- and long-term outcomes of TTS.
