“…TT cardiomyopathy is characterized by transient LV dysfunction with chest symptoms and ECG changes that mimic those of acute myocardial infarction in patients with normal findings on coronary angiography [3]. TT cardiomyopathy alone has not yet been explained, and it is speculated to be induced by emotional or physical stress [4].…”

The name ‘tako-tsubo’ cardiomyopathy was initially used to describe a unique ‘short-neck round-flask’-shaped form of left ventricular apical ballooning, resembling a Japanese tako-tsubo, a jar (tsubo) used for capturing octopus (tako). Tako-tsubo cardiomyopathy exhibits acute onset, transient left ventricular apical wall motion abnormalities with chest symptoms and minimal myocardial enzymatic release, mimicking acute myocardial infarction in patients without angiographic stenosis on coronary angiography. There have been few case reports on tako-tsubo cardiomyopathy, and this disorder is especially rare in pregnant women. A 30-year-old woman who was pregnant with triplets, and had been treated with ritodrine hydrochloride for 12 weeks for threatened premature delivery, underwent cesarean section with spinal anesthesia at 30 weeks’ gestation. Three hours later, she complained of acute chest pain, dyspnea and episodes of unconsciousness. She was transferred to the intensive care unit and intubated for ventilatory support. We diagnosed heart failure due to tako-tsubo cardiomyopathy based on heart ultrasonography, blood tests, chest X-ray, electrocardiogram and myocardial scintigraphy. She was extubated from the ventilator after 3 days of catecholamine, furosemide and carperitide administration. She was discharged from the hospital on day 53 without symptoms.

“…Regarding the triggering factors, a preceding acute medical condition induced TCM in 43% of cases and emotional factors in the remaining cases [2]. Our case series illustrates the very heterogeneous nature of the clinical presentations, triggering factors and outcomes severity in TCM.…”

“…It was first described in Japan and it was named Takotsubo cardiomyopathy (TCM) because of the resemblance between the left ventricular appearance in systole and the shape of a pot with a round bottom and a narrow neck (Takotsubo = Japanese octopus trap) [2,3]. This syndrome is characterized by acute LV dysfunction with regional wall motion abnormalities (WMA) extended beyond a single coronary vascular bed, absence of significant obstructive coronary obstructive disease, and rapid improvement of LV function within a few days or weeks [4].…”

We report a series of six consecutive cases of Takotsubo Cardiomyopathy (TCM) presenting as ST-elevation acute myocardial infarction and consequently addressed to the emergency coronary angiography, inside a time-frame of one year (2015). This series underlines the wide possible triggering spectrum and clinical severity of TCM and recognizes echocardiography as an essential imaging technique in the diagnosis due to its widespread availability and feasibility in the acute care setting.

“…However, two reports of myocardial biopsy in the setting of transient left ventricular dyskinesis resembling LVABS have been published. In both, the authors found focal myocyte injury which is not consistent with the concept of stunning [21,26]. Transient ischemic episodes due to epicardial coronary artery occlusion from spasm or thrombosis may lead to stunned myocardium or reperfusion injury.…”

Aims: Left ventricular apical ballooning syndrome (LVABS) is a clinical condition of unknown etiology, characterized by acute onset of atypical apical wall motion and absence of coronary artery disease. Gadolinium-enhanced cardiac magnetic resonance imaging (Gd-MRI) may be used to identify patients with myocarditis. Using cardiac MRI, we evaluated whether acute myocarditis may be an etiology that underlies LVABS. Methods and Results: Consecutive patients who presented with LVABS during a three-year period were included. Demographic data was recorded and echocardiography, coronary angiography, and hemodynamic assessment performed. Gd-MRI was performed in all patients. The study was deemed consistent with myocarditis when global myocardial to skeletal muscle enhancement ratio was ≥3.5. Regional Gd-MRI analysis was also performed. Patients (n = 11) were female (100%) and of mean age 72 years (72 ± 11). Preceding febrile illness occurred in 4 (36.3%) and leukocytosis in 6 (54.4%) patients. Initial mean left ventricular ejection fraction (41% ± 12%) improved (70.2% ± 8%) upon follow-up (39 ± 43 days). Global MRI analysis was positive in 5/11 (45.5%) (mean relative enhancement ratio 4.8 ± 1.4). Regional MRI analysis was positive in 4/6 further patients (overall: 9/11 (82%)). Conclusions: Gadolinium enhanced MRI imaging in LVABS implicates myocarditis as a possible etiology. Regional MRI analysis adds sensitivity to global cardiac MRI evaluation.
