1. Introduction Takotsubo cardiomyopathy (TTC) usually occurs in postmenopausal women after acute physical or mental stress and typically presents with apical ballooning of the left ventricle. TTC manifests with symptoms similar to acute coronary syndrome and may be accompanied by ECG changes, so coronary angiography is mandatory to exclude acute coronary syndrome.6,3 Other forms of TTC with atypical mid-ventricular ballooning have been described.5 Severe cerebral damage may also go along with ECG changes such as ST segment elevation, release of cardiac enzymes and/or cardiac dysfunction and often presents similar to TTC.5,2 For that reason a recent review postulates a pathophysiological relationship between TTC and cardiac dysfunction after cerebral bleeding.7 2. Case report We report on the case of a 56 year old female who was suffering from skull–brain trauma after bike accident. Shortly after the accident the patient grew comatose and was orotracheally intubated and transferred to the trauma department of our hospital. CCT revealed a minimal parenchymatous and subarachnoidal cerebral bleeding of the right frontal brain and a left-sided petrous bone fracture (Fig. 1). Two attempts of extubation failed due to quick respiratory insufficiency caused by cardiac decompensation. Therefore, cardiac enzymes were assessed and echocardiography was performed. Whereas creatine kinase was normal, troponine I was elevated up

to 6.8 ng/ml (norm < 0.04 ng/ml). Transthoracal echocardiography revealed high-grade global and regional reduction of the left ventricular function. ECG was without pathological findings of the ST-segment apart from discrete preterminal T-wave negativity in leads V3 to V6 but showed a modest prolonged QTc-time of 450 ms (Fig. 2). Acute myocardial infarction was suggested and the patient was transferred to our department of cardiology and underwent an emergency coronary angiography. Herein we did not find any significant coronary stenosis (Fig. 3A and B) but levocardiography confirmed severe left ventricular hypokinesia in the midventricular area with well-preserved contraction in apical and basal regions (Fig. 3C). We considered the tentative diagnosis of ‘‘inverted’’ takotsubo cardiomyopathy (iTTC). After control CCT that revealed no progress in bleeding, the patient was transferred to our intensive care unit. During the next hours the patient required high dosage of catecholamines. On the next day a cardiac magnetic resonance imaging (MRI) exam was performed. The scan confirmed the diagnosis of severe impairment of left ventricular function with akinesia of the midportion of the left ventricle (ejection fraction 25%). In line with echocardiographic findings, apical and basal contractility of the left ventricle was preserved (Fig. 3D and E). On late enhancement imaging no signs of myocardial necrosis or inflammation were found (Fig. 3F). In summary, cardiac MRI provided conclusive evidence of the diagnosis of iTTC. After 48 h patient’s condition improved, catecholamines were ceased and termination of mechanical ventilation was possible. Neurological examination showed no signs of sensoric or motoric impairment and no amnesia. Control echocardiography confirmed an improvement of left ventricular ejection fraction to 45% and after another surveillance period of 48 h at our intensive care unit the patient was transferred to another hospital after introduction of a heart failure medication with an ACE-Inhibitor and a beta-blocker. None of the daily ECGs showed any pathological signs except of the modest QTc-prolongation. The course of troponine, creatine kinase (CK) and myocardial band fraction of CK (CKMB) are illustrated in Fig. 4. Brain natriuretic peptide (NT-pro BNP) was measured two times and was elevated up to 10,895 pg/ml at the time of transfer to our ICU and 10,156 pg/ml 48 h later.

ventricle in levocardiography resembling a Japanese octopus trapping pot. By now, several cases of this syndrome have also been reported in Western populations. In 2004 Bybee et al. proposed the following clinical characteristics for the diagnosis of takotsubo cardiomyopathy3: (1) Transient akinesis or dyskinesis of the left ventricular wall with chest pain; (2) New electrocardiographic changes; (3) No significant coronary artery disease; (4) Absence of recent significant head trauma, intracerebral bleeding, phaeochromocytoma, myocarditis, and hypertrophic cardiomyopathy.

3. Discussion Several years ago, a new syndrome with transient left ventricular dysfunction has first been described in Japanese patients. This new entity was called takotsubo cardiomyopathy or apical ballooning due to the typical endsystolic shape of the left

Although the aetiology of this disease is unknown, the available evidence is consistent with the concept that extreme emotional (33–45%) and/or physical stress (17–22%) may trigger it.8 A predominance of postmenopausal women has been reported but the increased susceptibility of women and the potential genderrelated differences in the response to catecholamines is not well understood.11 Multivessel coronary spasms and catecholamine cardiotoxicity are suspected as underlying mechanism of TTC.4,1 Another type of transient left ventricular myocardial dysfunction has been reported in patients after subarachnoid haemorrhage. Already 50 years ago myocardial-ischaemia-like ECG changes have been reported after subarachnoid haemorrhage.9 Several studies report a reversible myocardial dysfunction with enzyme release after brain injury or cerebrovascular events2 in the absence of coronary artery disease.7 In summary, this transient myocardial dysfunction seems also to be catecholamine induced. TTC with, neurogenic stunning of the myocardium occurs

especially in postmenopausal women. TTC frequently affects apical segments of the left ventricle and normalizes within in a few days or weeks.7 Proposed criteria for the diagnosis of TTC3 postulate the exclusion of acute brain injury. However, the cardiotoxic mechanism in both disease patterns seems to be catecholamine induced. Implementing these criteria, our patient does not meet the diagnostic criteria of takotsubo. Nevertheless, the parenchymatous and subarachnoidal cerebral bleeding of the right frontal brain in our patient was small and without neurological impairment. We hypothesize that this minimal lesion could not solely cause the severe ventricular dysfunction in our case and that the midven-

tricular contraction impairment was induced by acute psychic stress during the accident. In accordance to Trio et al. we propagate that acute brain injury should not exclude the diagnosis of TTC.10 In fact, a new stress induced temporary myocardial dysfunction entity including patients after acute brain injury should be defined. This case especially emphasizes the impact of early interdisciplinary cooperation in trauma patients. Especially in prior healthy patients without cardiovascular risk factors after physical or mental stress, TTC is a potential differential diagnosis in patients with ECG-changes or elevated biomarkers of myocardial necrosis. Nevertheless, the early transfer of these patients to a department of cardiology is essential to exclude the main differential diagnosis of

Echocardiography in the hands of an experienced examiner is an additional useful tool to evaluate the left ventricular function and regional contraction abnormalities, especially at the ICU bedside, but is solely not sufficient to exclude significant coronary stenosis.
