近年来,Tako-Tsubo心肌病越来越受到关注,该病患者在左心室造影时发现心尖部呈气球样扩张及基底段缩窄,形态很像日本渔民用来捕捉章鱼的鱼篓,因此被命名为Tako-Tsubo心肌病、 相似文献

A 70-year-old female experienced severe anxiety due to an incident with a stranger when she was home alone at night. Immediately after the event, she had an oppressive chest sensation; 16 h later she was admitted to hospital. Left ventriculography showed akinesia of the mid-to-distal portion and hyperkinesia of the basal portion of the left ventricular chamber. However, coronary angiography showed no significant coronary artery disease. We diagnosed her as having Tako-Tsubo cardiomyopathy. Subsequently, left ventricular and central aortic pressures were recorded simultaneously. Initial recording showed a peak systolic gradient of 60 mm Hg. On the first sinus beat after a premature ventricular contraction, the peak systolic gradient increased to 130 mm Hg, and the pulse pressure decreased. Shortly after intravenous administration of nitroglycerin (0.5 mg), central aortic pressure decreased and the peak systolic gradient increased to 100 mm Hg. On the first sinus beat after a premature ventricular contraction, the peak systolic gradient increased to 160 mm Hg, and the pulse pressure decreased. Five minutes after intravenous nitroglycerin, the peak systolic gradient returned to 70 mm Hg. Follow-up transthoracic echocardiography 13 days later showed normal left ventricular wall motion with no pressure gradient through the left ventricular outflow tract. 相似文献

Severe emotional or physical stress precedes Tako-Tsubo cardiomyopathy (TTC) which is characterized by transient left ventricular impairment in absence of coronary artery disease. In this case we report from a female patient presenting with characteristic features of TTC after examination of upper gastrointestinal. Additionally, severe mitral regurgitation due to acute rupture of the posteromedial papillary muscle was present. Normal left ventricular function was documented before surgical valve repair was performed. TTC is reported to be associated with several complications. This is the first report of TTC accompanied by severe mitral valve regurgitation due to rupture of a papillary muscle. 相似文献

We present the case of a patient with Tako-Tsubo cardiomyopathy whose initial diagnosis, based on the location of shoulder and chest pain and electrocardiographic (ECG) changes, suggested that she was suffering from pericarditis. However, 24 h after admission, evolutionary changes of ECG and the echocardiogram performed suggested a Tako-Tsubo cardiomyopathy. In this context, we review the literature to discuss the clinical presentation and evolutionary ECG changes associated with Tako-Tsubo cardiomyopathy. 相似文献

Tako-Tsubo cardiomyopathy (TTC), also known as transient left ventricular (LV) ballooning syndrome or stress-induced cardiomyopathy, is characterised by transient LV dysfunction in the absence of significant angiographic coronary stenoses, frequently provoked by an episode of emotional or physical stress. In TTC, typically transient akinesis or dyskinesis of the LV apical segments with normal or hypercontractile basal wall motions is observed. Recently, several cases of atypical or inverted transient TTC sparing the LV apex have been reported. We report a case of inverted TTC showing akinesis of the basal and mid-ventricular segments of the LV with apical hyperkinesia triggered by bronchoscopy with bronchoalveolar lavage. 相似文献

Tako-Tsubo cardiomyopathy (TTC) predominantly affects elderly people with a high prevalence of cardiovascular risk factors. Therefore, one would expect to encounter incidental coronary artery disease in a significant number of cases. In fact, the prevalence of mild coronary artery disease (CAD), by angiography, has been reported to be in the range of 30%-60%. Similarly, more severe stenotic lesions in at least one coronary vessel were incidentally found in 10%-35% of patients with the disease. Using intravascular ultrasound in a series of 10 patients with TTC, coronary atherosclerosis was demonstrable in all patients, although five patients had normal coronary angiograms. Therefore, TTC and CAD are not mutually exclusive disease entities. The incidental finding of coronary lesions, even if significant, should not automatically lead to a dismissal of the diagnosis of TTC. Rather, a case-by-case approach using additional imaging modalities should be endorsed. 相似文献

We present a case of "inverted Tako-Tsubo" syndrome in a pre-menopausal woman with normal coronary arteries. Transient basal myocardial akinesia and ECG findings of healed myocardial infarction appeared shortly after emotional stress and resolved completely 4 days later. 相似文献

Takotsubo cardiomyopathy(TC) is characterized by reversible ventricular dysfunction, not limited to the distribution of an epicardial coronary artery. A disease primarily afflicting post-menopausal women, it is frequently mistaken for acute anterior wall myocardial infarction. Alternatively called Stress Cardiomyopathy, physical or emotional triggers are identified in only three fourths of TC patients. Long considered a benign condition, recent findings suggest poor short term prognosis similar to acute coronary syndrome(ACS). Despite the widely recognized pathophysiological role of catecholamine excess, its diagnostic role is uncertain. TC is suspected based on typical wall motion abnormalities in ventriculogram or echocardiogram. Several additional electrocardiographic, laboratory and imaging parameters have been studied with the goal of clinical diagnosis of TC. While several clinical clues differentiate it from ACS, a clinical diagnosis is often elusive leading to avoidable cardiac catheterizations. Natriuretic peptides(NPs), a family of peptide hormones released primarily in response to myocardial stretch, play a significant role in pathophysiology, diagnosis as well as treatment of congestive heart failure. TC with its prominent ventricular dysfunction is associated with a significant elevation of NPs. NPs are elevated in ACS as well but the degree of elevation is typically lesser than in TC. Markers of myocardial injury such as troponin are usually elevated to a higher degree in ACS than in TC. This differential elevation of NPs and markers of myocardial injury may play a role in early clinical recognition of TC. 相似文献
