Transient mid-ventricular ballooning cardiomyopathy: A new entity of Takotsubo cardiomyopathy

Midventricular Ballooning Takotsubo Cardiomyopathy Complicated by Transient Complete Atrioventricular Block

“…Although the underlying mechanism of Takotsubo cardiomyopathy is still not clearly understood, catecholamine surges in response to physiological or psychosomatic stress have been implicated in the onset of the disease (1-3). Recently, a few rare cases without typical apical ballooning have been reported (4,5). We herein report a variant case of Takotsubo cardiomyopathy with midventricular ballooning complicated by complete atrioventricular (AV) block.…”

The Use of Contrast-Enhancement Cardiovascular Magnetic Resonance Imaging in Cardiomyopathies

“…Several pathofysiological mechanisms have been proposed, including multivessel coronary spasm, catecholamine induced myocardial stunning, coronary emboli with spontaneous fibrinolysis, and myocardial inflammation (Eitel et al, 2010). Recently, variant forms are described, including inverted tako-tsubo and mid-ventricular ballooning cardiomyopathy (Marti et al, 2009;Yasu et al, 2006). In the setting of tako tsubo cardiomyopathy, CMR may identify increased myocardial mass and myocardial edema (using T2-weighted imaging) as well as the normalization of these parameters as the left ventricular dysfunction improves.…”

Tako-Tsubo Cardiomyopathy: A Recent Clinical Syndrome Mimicking an Acute Coronary Syndrome

“…www.intechopen.com Tako-Tsubo Cardiomyopathy: A Recent Clinical Syndrome Mimicking an Acute Coronary Syndrome 109 (Ohtsubo et al, 2005;Hurst et al, 2006;Tamura et al, 2007;Yasu et al, 2006). The fourth type is characterised by a localized wall motion abnormality affecting a segment of the left ventricle wall, usually the anterior wall (Suzuki et al, 2004;Lamm et al, 2007;Mazzarotto et al, 2005;Strunk et al, 2006).…”
