Fístula arteriovenosa pulmonar maciça. Causa rara, potencialmente curável de hipóxia neonatal.
(1996-06-01)
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 ...

Treatment of atrial fibrillation with radiofrequency ablation and simultaneous multipolar mapping of the pulmonary veins
(Sociedade Brasileira de Cardiologia - SBC, 2001-11-01)
OBJECTIVE: To demonstrate the feasibility and safety of simultaneous catheterization and mapping of the 4 pulmonary veins for ablation of atrial fibrillation. METHODS: Ten patients, 8 with paroxysmal atrial fibrillation ...
Purinergic receptor stimulation induces calcium oscillations and smooth muscle contraction in small pulmonary veins
(Wiley, 2018-07)
The small pulmonary veins (SPVs) may play a role in the development of pulmonary hypertension and pulmonary oedema via active changes in SPV diameter, mediated by vascular smooth muscle cell (VSMC) contraction. However, ...
Purinergic-dependent contraction of small intrapulmonary veins: role in a pulmonary arterial hypertension rat model
(2016)
Abstract Body : Background: For a long time, the vasoactivity of pulmonary veins has been debated. Increasing
evidences about the role of pulmonary veins to the total pulmonary vascular resistance has been particularly ...
Echocardiographic Assessment of the Pulmonary Venous Flow: An Indicator of Increased Pulmonary Flow in Congenital Cardiac Malformations
(Sociedade Brasileira de Cardiologia - SBC, 2002-06-01)
OBJECTIVE: To identify the left inferior pulmonary vein as an indirect marker of increased pulmonary flow in congenital heart diseases.METHODS: We carried out a prospective consecutive study on 40 patients divided into 2 ...
Pulmonary vein variants predispose to atrial fibrillation: a case-control study using multislice contrast-enhanced computed tomography
(OXFORD UNIV PRESS, 2011)
Aims Pulmonary veins (PV) play a pivotal role in atrial fibrillation (AF). Anatomical variants of PV have been described and related to a higher arrhythmogenic potential. The aim of this study was to compare the prevalence ...
Purinergic receptor stimulation induces Ca2+ oscillations and smooth muscle contraction in small pulmonary veins
(2014)
The small intrapulmonary veins (SPV) are thought to participate in the control of pulmonary blood flow
and its excessive contraction has been associated with the development of pulmonary edema. However,
the regulation of ...
ATP-induced contraction of small intrapulmonary veins in rats with pulmonary arterial hypertension.
(2016)
INTRODUCTION:
Pulmonary Arterial Hypertension (PAH) is a chronic, progressive and lethal disease. The etiology of elevated blood pressure in the pulmonary artery is still unknown. This condition characterized by increased ...
