1. Lung Cavities in Chronic Thromboembolic Pulmonary Hypertension
OBJECTIVES: Chronic thromboembolic pulmonary hypertension (CTEPH) is a unique form of pulmonary hypertension (PH) that arises from obstruction of the pulmonary vessels by recanalized thromboembolic material. CTEPH has a wide range of radiologic presentations. Commonly, it presents as main pulmonary artery enlargement, peripheral vascular obstructions, bronc

2. Anesthesia for renal transplantation in patients with dilated cardiomyopathy: a retrospective study of 31 cases
Resumo Justificativa e objetivos A cardiomiopatia dilatada é um estado de aumento progressivo das câmaras cardíacas, principalmente do ventrículo esquerdo, que leva à diminuição do débito cardíaco e, por fim, à insuficiência cardíaca. Embora tenha etiologia multifatorial, é bastante comum em pacientes com doença renal terminal que precisam de

3. Diagnóstico de hipertensão pulmonar em indivíduos adultos com doença falciforme / Diagnosis of pulmonary hypertension in adults with sickle cell disease
INTRODUCTION: Patients with sickle cell disease (SCD) and other haemolytic anaemia have increased prevalence of pulmonary hypertension (PH) that is related to higher mortality. The aim of this stdy was to determine the prevalence of PH and, its clinical, laboratorial and hemodynamic features. METHODS: In a crosssectional study, we evaluated 80 consecutive pa

4. Efeitos hemodinâmicos da ventilação não invasiva com pressão positiva em pacientes com estenose mitral sintomática / Hemodynamic effects of positive pressure noninvasive ventilation in patients with symptomatic mitral stenosis
Background: Continuous positive airway pressure (CPAP) impacts hemodynamic changes in heart failure patients by impending cardiac filling and reduces cardiac afterload by reducing left ventricular transmural pressure. These effects may collaborate for the success of this therapy in patients with pulmonary congestion. However, to your knowledge, no study has

5. Morphofunctional study of the junction between the left atrium and the pulmonary veins in patient with pulmonary hypertension
OBJECTIVE: To study the arrangement of the myocardial fiber bundles at the pulmonary venous left atrial junction in patients with pulmonary hypertension, and to discuss the pathophysiological importance of this element in the etiology of acute pulmonary edema. METHODS: We obtained 12 hearts and their pulmonary vein extremities from postmortem examinations of

6. Bone morphogenetic proteins, genetics and the pathophysiology of primary pulmonary hypertension
Several recent papers have shown that both familial primary pulmonary hypertension (FPPH) and sporadic primary pulmonary hypertension (PPH) may have a common etiology that is associated with the inheritance and/or spontaneous development of germline mutations in the bone morphogenetic protein receptor (BMPR) type II gene. Because BMPR-II is a ubiquitously ex

7. Monoclonal endothelial cell proliferation is present in primary but not secondary pulmonary hypertension.
The etiology and pathogenesis of the vascular lesions characterizing primary pulmonary hypertension (PPH), an often fatal pulmonary vascular disease, are largely unknown. Plexiform lesions composed of proliferating endothelial cells occur in between 20 and 80% of the cases of this irreversible pulmonary vascular disease. Recently, technology to assess monocl
