Tako Tsubo Cardiomyopathy

Background : The German tako-tsubo cardiomyopathy (TTC) registry has been initiated to further evaluate this syndrome in a western population. We aimed to assess different patterns of left ventricular involvement in TTC. Methods : Inclusion criteria were: 1) acute chest symptoms, 2) reversible ECG changes (ST-segment elevation±T-wave inversion), 3) reversible left ventricular dysfunction with a wall motion abnormality not corresponding to a single coronary artery territory, 4) no significant coronary artery stenoses. Results : A total of 258 patients (pts) from 33 centers were included with a mean age of 68±12 years. Left ventriculography revealed the typical pattern of apical ballooning in 170 pts (66%) and an atypical mid-ventricular ballooning with normal wall motion of the apical and basal segments in 88 pts (34%). Mean age (68±11 vs 67±13 years) and gender distribution (150 women/20 men vs 80 women/8 men) were similar in both groups. Triggering events were present in 78% of the pts with apical ballooning (35% emotional, 34 physical and 9% combination) and in 75% of the pts with mid-ventricular ballooning (39% emotional, 25% physical and 11% combination). As assessed by left ventriculography, ejection fraction was significantly lower in pts with mid-ventricular ballooning (50±15% vs 45±13%, p=0.006). There was no difference in right ventricular involvement. Creatine kinase and troponin I were comparable in both groups. The ECG on admission showed ST-segment elevation in 87% of pts with apical ballooning and in 78% of pts with mid-ventricular ballooning. T-wave inversion was seen in 70% of the pts irrespective of the TTC variant. A Q-wave was significantly less present in pts with mid-ventricular ballooning (30% vs 16%, p=0.04). The QTc interval during the first 3 days was not different among both groups. Conclusion : A variant form with mid-ventricular ballooning was observed in one third of the pts with TTC. Left ventricular ejection fraction was significantly lower in these pts, although they revealed significantly less Q-waves on the admission ECG. All other parameters were similar and confirm the concept that apical and mid-ventricular ballooning represent two different manifestations of the same syndrome.

Objective: We present the case of possible reverse type of TCM in a female patient presented with progressive left ventricular dysfunction and its rupture in pericardium. Methods: The detailed history, physical examination, laboratory tests, electrocardiography, serial echocardiography, coronary angiography with left ventriculography were performed to diagnose possible Takotsubo cardiomyopathy in 63-year old woman admitted to our center with complaints of dyspnea, lightheadedness, weakness and signs of hypotension and history of inferior myocardial infarction, acute left ventricular aneurysm, and effusive pericarditis and pleuritis, developed after emotional stress 5 months ago. Results: Clinical evaluation revealed unremarkable laboratory tests, normal troponin values, signs of old inferior myocardial infarction on electrocardiogram, and left ventricular (LV) dilatation and dysfunction, akinesia of LV infero-lateral wall with thinning and its rupture and blood shunting in pericardium. Her coronary angiography revealed normal coronary arteries. The diagnosis of pheochromocytoma was excluded. The patient underwent surgery under cardiopulmonary bypass with removal of LV pseudoaneurysm. The patient was discharged from hospital with improvement in NYHA class and LV function. Conclusion: Thus, in female postmenopausal patients presenting with acute myocardial infarction signs complicated by pericarditis, intact coronary arteries and LV dysfunction with emotional stress as triggering factor, reverse type of TCM should be considered and proper management applied to prevent development of life-threatening complications like LV rupture.
