  • Congenital heart defects are found in 50% of pulmonary artery sling cases, most commonly atrial septal defect , patent ductus arteriosus , ventricular septal defect , and left superior vena cava. (medscape.com)
  • [ 1 ] In this report, Muller and Danimann described palliation by the "creation of pulmonary stenosis" in a 5-month-old infant who had a large ventricular septal defect (VSD) and pulmonary overcirculation. (medscape.com)
Systemic to pulmonary1
  • Scholars@Duke publication: Clopidogrel in infants with systemic-to-pulmonary-artery shunts. (duke.edu)
Venous1
  • Unlike in other organs where arteries supply oxygenated blood, the blood carried by the pulmonary arteries is deoxygenated, as it is venous blood returning to the heart. (wikipedia.org)
Angiography1
Main12
  • The largest pulmonary artery is the main pulmonary artery or pulmonary trunk from the heart, and the smallest ones are the arterioles, which lead to the capillaries that surround the pulmonary alveoli. (wikipedia.org)
  • The pulmonary trunk splits into the right and the left main pulmonary artery. (wikipedia.org)
  • The right pulmonary artery pass across the midline of the body, below the carina of trachea, and comes in front of the right main bronchus. (wikipedia.org)
  • 790 The pulmonary artery pressure (PA pressure) is a measure of the blood pressure found in the main pulmonary artery. (wikipedia.org)
  • Pulmonary artery banding (PAB) creates a narrowing, or stenosing, of the main pulmonary artery that decreases blood flow to the branch pulmonary arteries and reduces PBF and pulmonary artery pressure. (medscape.com)
  • What is the normal size of the main pulmonary artery? (onteenstoday.com)
  • Before the aortic cross-clamp, the main pulmonary artery (PA) was also snared. (ctsnet.org)
  • In order of blood flow, the pulmonary arteries start as the pulmonary trunk or main pulmonary artery . (iiab.me)
  • The main pulmonary artery begins at the base of the right ventricle . (iiab.me)
  • The right main pulmonary artery follows a longer and more horizontal course as it crosses the mediastinum . (iiab.me)
  • A CT thorax with contrast showed enlarged main pulmonary artery, right and left pulmonary arteries with a thrombotic fusiform aneurysm of right Pulmonary artery. (peertechzpublications.com)
  • Most involve the main trunk of the Pulmonary artery with or without involvement of its branches. (peertechzpublications.com)
Hemodynamic1
Unilateral3
  • Unilateral absence of pulmonary artery (UAPA) is a rare congenital anomaly that can present as an isolated lesion or may be associated with other Congenital heart diseases . (narayanahealth.org)
  • Congenital "unilateral absence of a pulmonary artery" is a rare malformation. (narayanahealth.org)
  • Only few cases of unilateral pulmonary artery agenesis have been reported from India. (narayanahealth.org)
Originates3
  • In children with ALCAPA, the LCA originates from the pulmonary artery. (medlineplus.gov)
  • The pulmonary artery, or pulmonary trunk, originates from the bottom of the right ventricle of the heart. (healthline.com)
  • The pulmonary trunk is a major vessel of the human heart that originates from the right ventricle. (healthline.com)
Arterioles3
  • Apparent hypoxic changes in pulmonary arterioles and small arteries in infancy. (bmj.com)
  • The pulmonary arterioles and small arteries were studied and their musculature and its nuclei were quantified in 90 neonates, infants, and young children who had suffered from a variety of clinical and hypoxic conditions immediately before death. (bmj.com)
  • No evidence was found to support the view that cases of SIDS are subjected to chronic hypoxia before death as significantly more medial muscle tissue in the pulmonary arterioles and small arteries was found in the chronic hypoxic group compared to the SIDS, non-hypoxic, and acute hypoxic groups. (bmj.com)
Bifurcation2
  • To obtain a better prognosis in cases demonstrating an involvement of the bifurcation of pulmonary artery, more effective combined treatment still needs to be developed. (minervamedica.it)
  • The maximal PA and Ao diameters were measured on transverse slices, near the bifurcation of the right and left pulmonary arteries and the mid-point of the aortic arch respectively. (avmi.net)
Obstruction1
  • however, because many demonstrate some persistent airway obstruction, they should be closely observed for both airway as well as pulmonary artery complications. (medscape.com)
Vascular resistance2
  • At baseline, the mean 6-minute walk distance was 401 meters, mean pulmonary arterial pressure was 53.9 mm Hg, mean pulmonary vascular resistance was 10.9 Wood units, and mean N-terminal pro-brain natriuretic peptide (NT-proBNP) level was 2345 pg/mL. (medscape.com)
  • Congenital heart defects with left-to-right shunting and unrestricted pulmonary blood flow (PBF) due to a drop in pulmonary vascular resistance result in pulmonary overcirculation. (medscape.com)
Alveoli1
  • At the far end, pulmonary arteries (labeled at bottom) become capillaries at the pulmonary alveoli . (iiab.me)
Branch3
Capillary wedge1
  • The target in both groups was resolution of clinical congestion, with additional PAC targets of a pulmonary capillary wedge pressure of 15 mm Hg and a right atrial pressure of 8 mm Hg. (elsevierpure.com)
