Pathology of Takotsubo (Ampulla) Cardiomyopathy
نویسنده
چکیده
Takotsubo (ampulla) cardiomyopathy is characterized by slight to moderate elevation of cardiac enzymes. It is reasonable to think that the elevated levels are evidence of myocardial damage (cardiac-specific enzymes are released from the cytoplasm of damaged cardiac myocytes into extracellular fluid). Thus, it is problematic to consider takotsubo cardiomyopathy as (neurogenic) stunned myocardium, because stunned myocardium is defined as a state without histopathological changes observable by light microscopy.1 In the study, I will describe histological findings in autopsied cases in Japan and histopathological findings of endomyocardial biopsy cases with a literature review.

Morphologically unique feature of recurrent ampulla (takotsubo) cardiomyopathy.
Two similar rare cases of recurrent ampulla (takotsubo) cardiomyopathy, which was induced by physical stress of recurrent rhabdomyolysis in case 1 and aggravation of respiratory disease in case 2, are presented. At the initial admission, both patients had typical ampulla cardiomyopathy, which was indicated by transient left ventricular (LV) apical ballooning, but at the second admission, they b...

Takotsubo cardiomyopathy (TC), synonymous with apical ballooning syndrome, broken heart syndrome, stress induced/ ampulla cardiomyopathy is characterized by transient left ventricular dysfunction of apical ( typical) or mid segments (atypical), mimicking acute myocardial infarction in the absence of significant coronary artery disease . We report a rare case of recurrent takotsubo cardiomyopath...

UNLABELLED We assessed Takotsubo (ampulla) cardiomyopathy compared with acute coronary syndrome (ACS) using two-dimensional echocardiography and 99mTc-tetrofosmin myocardial SPECT. METHODS We examined 10 patients with Takotsubo cardiomyopathy and 16 with ACS at the time of emergency admission (acute phase), at three to nine days after the attack (subacute phase) and at one month after the att...

Ampulla cardiomyopathy (Takotsubo cardiomyopathy) is a syndrome, consisting of acute-onset, transient, and abnormal left ventricular wall motion with apical akinesis and basal normokinesis without any detectable coronary lesions. The syndrome has symptoms and signs that are similar to acute myocardial infarction, such as electrocardiogram (ECG) changes (ST-segment elevation and subsequent giant...
متن کاملGuidelines for diagnosis of takotsubo (ampulla) cardiomyopathy.
BACKGROUND It is important to differentiate takotsubo cardiomyopathy from other types of transient ventricular dysfunction. These guidelines, resulting from a workshop sponsored by the Ministry of Health, Labour, and Welfare, Idiopathic Cardiomyopathy Research Committee, outline the steps necessary for diagnosis of takotsubo cardiomyopathy. METHODS AND RESULTS The survey was conducted by mail...
