| shift to the right | In a differential count of white blood cells in the peripheral blood, the absence of young and immature forms. Synonym: deviation to the right. See: maturation index. (05 Mar 2000) |
|---|---|
| shunt, left to right | A term used to describe the diversion of blood from the higher pressure left side of the heart to the right side (pulmonary circuit). Can be seen in ventricular septal defect, atrial septal defect and patent ductus arteriosus (congenital at birth). (27 Sep 1997) |
| shunt, right to left | <cardiology> A term used to describe the diversion of blood from the right side of the heart to the left. Long standing left to right shunts can lead to increased right sided pressures in the pulmonary circuit (pulmonary hypertension). Eventually the left to right shunt reverses and blood flows from the right to the left. Can be seen in large untreated ventricular septal defect or atrial septal defect. (27 Sep 1997) |
| hypertrophy, right ventricular | Enlargement of the right ventricle of the heart. This increase in ventricular mass is often attributed to pulmonary hypertension and is a contributor to cardiovascular morbidity and mortality. (12 Dec 1998) |
| hypoplasia of right ventricle | Failure of development of the right ventricle resulting in its having little muscle and much connective tissue instead of the reverse. (05 Mar 2000) |
| superior branch of the right and left inferior pulmonary veins | Tributaries of the right and left inferior pulmonary veins which receive oxygenated blood from the superior [S6] bronchopulmonary segments of the inferior lobes of the right and left lungs. Synonym: ramus superior venae pulmonalis dextrae/sinistrae inferioris. (05 Mar 2000) |
| deviation to the right | In a differential count of white blood cells in the peripheral blood, the absence of young and immature forms. Synonym: deviation to the right. See: maturation index. (05 Mar 2000) |
| double outlet right ventricle | <cardiology, embryology> Incomplete transposition of the great vessels in which both the aorta and the pulmonary artery arise from the right ventricle, often associated with a subaortic ventricular septal defect. (12 Dec 1998) |
| infralobar part of posterior branch of right pulmonary vein | <anatomy, vein> The vein draining the posterior segment of the right lung that emerges inferior to the superior lobe; tributary to the posterior branch of the right superior pulmonary vein. Synonym: pars infralobaris rami posterioris venae pulmonalis dextrae. (05 Mar 2000) |
| intralobar part of the right superior pulmonary vein | <anatomy, vein> The vein draining the apical and posterior segments of the right lung; tributary to the posterior branch of the right superior pulmonary vein. Synonym: pars intralobaris venae pulmonalis dextrae superioris. (05 Mar 2000) |
| left-to-right shunt | A diversion of blood from the left side of the heart to right (as through a septal defect), or from the systemic circulation to the pulmonary (as through a patent ductus arteriosus). (05 Mar 2000) |
| left-to-right shunts | <radiology> Atrial septal defect, ventricular septal defect, patent ductus arteriosus, aorticopulmonary window, endocardial cushion defect, partial anomalous pulmonary venous return (12 Dec 1998) |
| air-conditioner lung | An extrinsic allergic alveolitis caused by forced air contaminated by thermophilic actinomycetes and other organisms. (05 Mar 2000) |
| airless lung | <radiology> Tumour, foreign body, mucous plug (12 Dec 1998) |
| anterior border of lung | The thin anteromedial or sternal edge of the lung which overlaps the pericardial sac anteriorly and forms the boundary between the mediastinal and costal surfaces. Synonym: margo anterior pulmonis. (05 Mar 2000) |
