Large septic pulmonary embolus complicating streptococcus mutans pulmonary valve endocarditis
(EduRad Publishing, 2018)
Large septic pulmonary embolus is a rare finding in right-sided endocarditis. The entity represents a challenging diagnosis due to its variable and nonspecific clinical and radiological presentation and similarities with ...
Clinical and haemodynamic evaluation of chronic thromboembolic pulmonary hypertension patients scheduled for pulmonary thromboendarterectomy: Is schistosomiasis hypertension an important confounding factor?
(Faculdade de Medicina / USP, 2010)
INTRODUCTION: Chronic thromboembolic pulmonary hypertension is a disease affecting approximately 4,000 people per year in the United States. The incidence rate in Brazil, however, is unknown. The estimated survival for ...
Can we start to think about consensus-oriented clinical practices?
(CAMBRIDGE UNIV PRESS, 2009)
Revisiting the role of TRP, orai, and ASIC channels in the pulmonary arterial response to hypoxia
(Frontiers Media S.A., 2018)
© 2018 Reyes, Castillo-Galán, Hernandez, Herrera, Ebensperger and Llanos. The pulmonary arteries are exquisitely responsive to oxygen changes. They rapidly and proportionally contract as arterial PO2 decrease, and they ...
Fístula arteriovenosa pulmonar maciça. Causa rara, potencialmente curável de hipóxia neonatal.
The case of a six-day-old neonate admitted in an emergency situation because of dyspnea and increasing cyanosis is reported. Despite abnormal opacification on the chest X-ray and left ventricular overload on the electrocardiogram ...
Chromosome 22q11 deletion in a patient with pulmonary atresia, intact ventricular septum, and confluent branch pulmonary arteries
(Cambridge University Press, 2018)
In this study, we report a patient with pulmonary atresia with intact ventricular septum (PA/IVS), confluent pulmonary arteries supplied by an arterial duct, and chromosome 22q11.2 microdeletion. The 22q11.2 deletion ...
Hypoxic pulmonary vasoconstriction in reptiles: a comparative study of four species with different lung structures and pulmonary blood pressures
(Amer Physiological Soc, 2005-11-01)
Low O-2 levels in the lungs of birds and mammals cause constriction of the pulmonary vasculature that elevates resistance to pulmonary blood flow and increases pulmonary blood pressure. This hypoxic pulmonary vasoconstriction ...
Long-term exposure to high-altitude chronic hypoxia during gestation induces neonatal pulmonary hypertension at sea level
We determined whether postnatal pulmonary hypertension induced by 70% of pregnancy at high altitude (HA) persists once the offspring return to sea level and investigated pulmonary vascular mechanisms operating under these ...
Melatonin decreases pulmonary vascular remodeling and oxygen sensitivity in pulmonary hypertensive newborn lambs
(Frontiers media SA, 2018)
Background: Chronic hypoxia and oxidative stress during gestation lead to pulmonary hypertension of the neonate (PHN), a condition characterized by abnormal pulmonary arterial reactivity and remodeling. Melatonin has strong ...
