Electrocardiogram in Endomyocardial Fibrosis
نویسنده
چکیده
Endomyocardial fibrosis (EMF) is a distinct obliterative cardiomyopathy characterized anatomically by right/left/bi ventricular endocardial fibrotic thickening and varying degrees of obliteration of the ventricular cavity. Chamber obliteration leads to diastolic restriction to ventricular filling and thus diastolic ventricular dysfunction. Involvement of the chordae tendinae and papillary muscles in the fibrotic process results in atrioventricular (AV) valve regurgitation. The ventricular endocardial thickening is predominantly at apex leading to apical obliteration. When it extends to the inflow, papillary muscles and chordae are involved and AV valve regurgitation ensues. The hemodynamics is that of a restrictive cardiomyopathy with varying degrees of AV valve regurgitation.

Primary restrictive cardiomyopathy. Non-tropical endomyocardial fibrosis and hypereosinophilic heart disease.
Eleven patients with a restrictive cardiomyopathy are described. Seven of these had biventricular disease and in them the haemodynamic abnormality resembled that in constrictive pericarditis but the condition was distinguishable because of unequal involvement of the two ventricles, murmurs of atrioventricular valve regurgitation, or characteristic ventricular deformity on angiography. Two of th...

Endomyocardial fibrosis is a common cause of heart failure in Uganda. A clinico-pathological study of this cardiopathy reported by Ball et al. (1954) established that the fibrotic process, while involving the endocardium of the apices of the ventricles, not infrequently extends to the chorda, tendinee and the cusps of the atrioventricular valves, tethering them down and producing atrioventricul...

Endomyocardial biopsy is the gold standard for diagnosing viral myocarditis. However, this method is rarely used as it is more invasive, less sensitive and has a higher incidence of complications than other methods. With recent developments in myocarditis research, cardiovascular nuclear magnetic resonance imaging has been demonstrated to have a marked advantage over endomyocardial biopsy, spec...
متن کاملRight ventricular endomyocardial fibrosis.
Endomyocardial fibrosis is a variety of restrictive cardiomyopathy, in which endocardium of one or both ventricles is thickened markedly with involvement of underlying myocardium. Partial obliteration of ventricular cavities by fibrous tissue and thrombus causes diastolic dysfunction with increased resistance to ventricular filling. Systolic function is well preserved till late stages. Biventri...
