1. Surgical Management of The Endomyocardial Fibrosis of Right Ventricle Mimicking Tumor with Recurrent Pulmonary Embolism
ABSTRACT Endomyocardial fibrosis is a neglected tropical disease that leads to restrictive cardiomyopathy. Its etiopathogenis is unclear and involves the progression of 3 stages of the disease. Compared with echocardiography, cardiac magnetic resonance imaging shows better apical visualization of obliteration and thrombus and provides an early diagnosis. How

2. Hematology and Histopathology of Broiler Chickens Supplemented with Tuna Black Flour
ABSTRACT The present study evaluated the effect of the sex and dietary intake of tuna black flour (TBF)on the hematology and histopathology of broiler chickens. A total of 200 sexed broilers (Ross 380) were distributed according to a completely randomized design into four treatments (25 males and 25 females/experimental group).Different levels of inclusion o

3. Valvular Disorders in Carcinoid Heart Disease
Abstract Carcinoid heart disease is a rare but important cause of intrinsic right heart valve disorders leading to right heart failure. Occasionally, left-sided heart valves may also be involved. The characteristic cardiac pathological findings of carcinoid heart disease are endocardial thickening as a result of fibrous deposits on the endocardium. Echocardi

4. Estudo experimental comparativo entre a derivação cavo-pulmonar associada ao suporte circulatório esquerdo e o suporte circulatório biventricular na falência aguda biventricular / Comparative experimental study between cavopulmonary anastomosis associated with left ventricular assist device support and biventricular circulatory assistance in acute biventricular failure
Background Right ventricular (RV) failure durinq left ventricular assist device (LVAD) support can result in severe hernodynarnic cornpromise with hiqh mortality. Objective: This study investiqated the acute effects of cavopulmonary anastomosis on L VAD performance and riqht ventricular myocardial compromise in comparison with isolated LVAD support and biven

5. Efeitos do exercício físico sobre as propriedades morfológicas e mecânicas de miócitos cardíacos de ratos diabéticos / Effects of exercise on the morphological and mechanical properties of cardiac myocytes from diabetic rats
The aim of this study was to verify the effects of a swimming training (ST) on the morphological and mechanical properties of cardiac myocytes from different regions of the left ventricle (LV) of rats with experimental diabetes. One month old male Wistar rats (body mass ~ 250g) received an intraperitoneal injection of Streptozootocin (STZ, 60mg/kg body mass)

6. Mapeamento eletroanatômico epicárdico e endocárdico combinado associado à ablação por radiofrequência em pacientes com cardiomiopatia chagásica e taquicardia ventricular. / Combined epicardial and endocardial substrate mapping and radiofrequency catheter ablation for ventricular tachycardia in chronic chagasic cardiomyopathy.
Background: Slow conduction scarred areas are related with ventricular tachycardia (VT) arrhythmogenesis in nonischemic cardiomyophathy. The purpose of this study was to characterize the substrate in both epicardial and endocardial surfaces of the left ventricle and to evaluate the effectiveness of substrate mapping and ablation for VT in Chagas cardiomyopat

7. A queda da pressão de perfusão coronariana implica em dano subendocárdico da região do miocárdio remota ao infarto e em disfunção do ventrículo esquerdo / Low coronary driving pressure early in the course of myocardial infarction determines subendocardial remodeling and left ventricular dysfunction
No infarto, o remodelamento da região ventricular remota tem sido pouco examinado. Previamente, observamos que a redução da pressão de perfusão coronariana (PPC) associa-se ao aparecimento de fibrose subendocárdica. O objetivo do presente estudo foi investigar o papel da PPC no remodelamento e na função ventricular esquerda após o infarto. Medidas h

8. Factors released from endocardium of the ferret and pig modulate myocardial contraction.
1. In isolated heart muscle preparations, selective removal of the endocardium results in a characteristic and unusual negative inotropic effect. Possible mechanisms for this effect were investigated in this study. 2. In endocardium-intact preparations of ferret papillary muscle, 8-bromo-cyclic GMP, sodium nitroprusside, atrial natriuretic peptide (ANP) and

9. Endocardial fibroelastosis in children with special reference to the lesions of cardiac ganglia
In all cases of primary endocardial fibroelastosis investigated diffuse degenerative changes in the ganglion cells were detected. Thickened endocardium was formed by the proliferation of mesenchymal cells located under the endothelial endocardium and of the mesenchyme surrounding the necrobiotic muscle cells. In some cases `axial' vacuolar degeneration, necr

12. Endocardial lesion in a case of Takayasu's arteriopathy.
The clinical findings and the necropsy report of a 14-year-old girl suffering from Takayasu's arteriopathy have been presented. In addition to the typical arterial changes, thickening and puckering of the aortic valve and a patch of thickening in the left atrial endocardium were shown at necropsy. The histology of this lesion was found to be identical with t
