| 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) |
| 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) |
| 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) |
| accessory meningeal branch of middle meningeal artery | <anatomy, artery> A branch of either the middle meningeal or maxillary artery in the infratemporal fossa and passing superiorly through the foramen ovale to supply the trigeminal ganglion, dura mater and inner table of bone. Synonym: ramus meningeus accessorius arteriae meningeae mediae. (05 Mar 2000) |
| acetabular branch | An arterial branch that supplies the acetabulum; two arteries, the obturator and the medial femoral circumflex, have such branches. Synonym: ramus acetabularis, acetabular artery, arteria acetabuli. (05 Mar 2000) |
| acromial branch of suprascapular artery | <anatomy, artery> Branch of suprascapular artery which pierces the origin of the trapezius muscle to run to the acromion; anastomoses, acromial branch of thoracoacromial artery. Synonym: ramus acromialis arteriae suprascapularis. (05 Mar 2000) |
| acromial branch of thoracoacromial artery | <anatomy, artery> A branch of the thoracoacromial artery that runs over the coracoid process and under the deltoid muscle. Synonym: ramus acromialis arteriae thoracoacromialis, acromial artery. (05 Mar 2000) |
| anastomotic branch | The anastomotic branch, a blood vessel that interconnects two neighboring vessels. It should not be used for the nervous system, because there is no analogy between a vascular anastomosing branch and a connection between nerves or their subdivisions. Synonym: ramus anastomoticus. (05 Mar 2000) |
| anastomotic branch of middle meningeal artery to lacrimal artery | <anatomy, artery> A branch of the middle meningeal artery arising in the cranial cavity which runs anteriorly through the superior orbital fissure to anastomose with the lacrimal artery. See: orbital branch of middle meningeal artery. Synonym: ramus anastomoticus arteriae meningeae mediae cum lacrimali. (05 Mar 2000) |
