Right 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...
متن کاملRight ventricular endomyocardial fibrosis. Diagnosis and management.
The clinical course, noninvasive and invasive diagnostic findings in 4 patients (pt) with endomyocardial fibrosis are reported. All patients (16-50 years) were in functional class III-IV (NYHA). Central venous pressure with large a- and v-waves was elevated in all; liver enlargement and peripheral edema were also noticed in all pts, and ascites in 3. An apical 2/6 systolic murmur was present in...
متن کاملRelationship between the ECG, ventricular activation, and the ventricular conduction system in ostium primum ASD.
SUMMARY A combined electrophysiologic-anatomic study was performed in a dog with a congenital atrial septal defect (ASD) primum. Comparisons were made between the dog and electrophysiologic data obtained in four patients with ASD primum. The ECGs and VCGs in both the dog and patients revealed the characteristic features of superior orientation, counterclockwise rotation, and slow-rightward term...
متن کاملEchocardiography in the diagnosis of right ventricular endomyocardial fibrosis.
Twenty-one patients with endomyocardial fibrosis (EMF) and right ventricular involvement were studied by M-mode echocardiography. All 21 patients showed echocardiographic findings consisting of (i) increased right ventricular dimension, (ii) paradoxical septal motion, (lii) increased right ventricular outflow dimension (iv) thickening of the right ventricular anterior wall with increased right ...
متن کاملUltrastructural evidence of intercalated disc remodelling in arrhythmogenic right ventricular cardiomyopathy: an electron microscopy investigation on endomyocardial biopsies.
AIMS The ultrastructural features of the myocardium in arrhythmogenic right ventricular cardiomyopathy (ARVC) have not been systematically investigated so far. The recent discovery of gene mutations encoding intercalated disc proteins prompted us to perform a transmission electron microscopy study on endomyocardial biopsies. METHODS AND RESULTS Twenty-one ARVC probands who fulfilled the inter...
