OBJECTIVES: Our aim was to determine whether myocardial fibrosis, detected by cardiovascular magnetic resonance (CMR), represents an arrhythmogenic substrate in hypertrophic cardiomyopathy (HCM). BACKGROUND: Myocardial fibrosis is identified frequently in HCM; however, the clinical significance of this finding is uncertain. METHODS: We studied prevalence and frequency of tachyarrhythmias on 24-h ...

Apical hypertrophic cardiomyopathy is a form of hypertrophic cardiomyopathy localized to the left ventricular apex. It is common in Japanese and other Asian populations, where it is generally considered relatively benign. However, its presence has also been recognized, though less commonly, in non-Asian patients. In these patients, the electrocardiographic changes ...

Takotsubo cardiomyopathy is a recently recognised acute cardiac entity. It involves transient left ventricular apical ballooning, which is usually preceded by an episode of physiological or emotional stress. Its presentation may mimic acute myocardial infarction but there is no evidence of obstructive disease at coronary angiography. The aetiology of this ...
Mohamed, H A; ;
Tako-tsubo cardiomyopathy (transient left ventricular apical ballooning) is a reversible form of cardiomyopathy of unknown etiology. Tako-tsubo Cardiomyopathy (TTC) is typically precipitated by sudden emotional or physical stress, and is associated with excessive sympathetic stimulation and catecholamine release. Its clinical presentation is similar to that of acute coronary syndrome. The ...

Isolated ventricular non-compaction is a rare type of cardiomyopathy resulting from arrested myocardial development during embryogenesis. This rare entity can be easily diagnosed by characteristic appearance of prominent myocardial trabeculations and deep inter-trabecular spaces. The clinical manifestations include heart failure signs, ventricular arrhythmias, and cardio-embolic events. Although the usual site ...

Patients with hypertrophic cardiomyopathy (HCM) are inherently prone to arrhythmias. Electroconvulsive therapy (ECT), a well-known treatment in psychiatry, leads to a catecholamine surge and may cause arrhythmias in patients with severe coronary and valvular heart diseases and heart failure. Whether ECT is safe in HCM is unknown. We systematically investigated ...

BACKGROUND: Young, trained athletes may have abnormal 12-lead electrocardiograms (ECGs) without evidence of structural cardiac disease. Whether such ECG patterns represent the initial expression of underlying cardiac disease with potential long-term adverse consequences remains unresolved. We assessed long-term clinical outcomes in athletes with ECGs characterized by marked repolarization abnormalities. METHODS: ...

"Takotsubo cardiomyopathy" is characterized by transient LV dysfunction and mimicking acute myocardial infarction. We reported a case with atypical presentation of "takotsubo cardiomyopathy" without ST segment elevation, but with severe transient left ventricular dysfunction. Diagnosis of "takotsubo cardiomyopathy" should be based on typical left ventricular dysfunction without coronary artery disease.

Takotsubo cardiomyopathy is a form of transient, reversible left ventricular dysfunction that can mimic an acute coronary event. However, cardiac catheterization often reveals normal coronary arteries. Patients are often postmenopausal women who experience acute physical or emotional distress. The prognosis for this entity is quite favorable. In this report, we ...

Amyloid cardiomyopathy is characterized by non-dilated thick-walled left ventricular, thickening of interventricular septum and right ventricular free wall, biatrial enlargement associated with granular 'sparkling' appearance of the myocardium. Typically, decreased left ventricular compliance results in abnormal diastolic functions but left ventricular systolic functions are preserved until late in the course ...

Stress cardiomyopathy, also referred to as Takotsubo cardiomyopathy, is an increasingly recognized clinical syndrome characterized by acute reversible apical ventricular dysfunction. We hypothesize that stress cardiomyopathy is a form of myocardial stunning, but with different cellular mechanisms to those seen during transient episodes of ischemia secondary to coronary stenoses. In ...

Hypertrophic cardiomyopathy and cardiac amyloidosis result in thickening of the left ventricle, as visualized by 2-dimensional echocardiography. Hemodynamically, hypertrophic cardiomyopathy can be typified by a left ventricular outflow tract gradient and systolic anterior motion of the mitral apparatus, findings rarely seen in cardiac amyloidosis. This case series reports 4 patients ...

We investigated if myocardial edema is a feature of Tako-Tsubo cardiomyopathy (TTC). Seven TTC patients in the acute phase were studied using cine, T2 and late enhancement cardiovascular magnetic resonance (CMR). A transmural area of high T2 signal was visible involving the mid-anterior wall and apical segments matching the distribution ...

Tako-tsubo cardiomyopathy is a recently described form of transient ventricular dysfunction that is not associated with coronary vessels obstruction, although its clinical manifestations are often similar to those of myocardial ischemia. This syndrome is possibly due to an excess of catecholamines, and it is associated with emotional and physical stress ...

Left ventricular outflow tract (LVOT) obstruction is a typical recognized feature in hypertrophic cardiomyopathy. However, it has been shown in other clinical scenarios such as acute ischemia. In some patients, LVOT obstruction may only be detectable with provocation testing such as exercise stress. Accurate and timely diagnosis, therefore, relies on ...

A 31-year-old woman presented with dyspnea and left-sided chest discomfort and was found to have biventricular heart failure with impaired ventricular filling. Clinically, she was thought to have restrictive cardiomyopathy or constrictive pericarditis. Transmission electron microscopy of myocardial tissue unexpectedly revealed crosshatched, curvilinear, and fingerprint depositions, which were characteristic for ...
