| ventricular function, left | The haemodynamic and electrophysiological action of the left ventricle. Its measurement is an important aspect of the clinical evaluation of patients with heart disease to determine the effects of the disease on cardiac performance. (12 Dec 1998) |
|---|---|
| circumflex branch of left coronary artery | <anatomy, artery> Terminal branch (with anterior interventricular artery) of left coronary artery which runs to left and then posteriorly in the coronary groove supplying atrial and ventricular branches. Synonym: ramus circumflexus arteriae coronariae sinistrae. (05 Mar 2000) |
| posterior vein of left ventricle | Arises on the diaphragmatic surface of the heart near the apex, runs to the left and parallel to the posterior interventricular sulcus, and empties in the coronary sinus. Synonym: vena posterior ventriculi sinistri. (05 Mar 2000) |
| shift to the left | A marked increase in the percentage of immature cells in the circulating blood, based on the premise in haematology that the bone marrow with its immature myeloid cells is on the left, while the circulating blood with its mature neutrophils is on the right. Synonym: deviation to the left. See: maturation index. (05 Mar 2000) |
| hypertrophy, left ventricular | Enlargement of the left ventricle of the heart. This increase in ventricular mass is attributed to sustained abnormal pressure or volume loads and is a contributor to cardiovascular morbidity and mortality. (12 Dec 1998) |
| deviation to the left | A marked increase in the percentage of immature cells in the circulating blood, based on the premise in haematology that the bone marrow with its immature myeloid cells is on the left, while the circulating blood with its mature neutrophils is on the right. Synonym: deviation to the left. See: maturation index. (05 Mar 2000) |
| ischemic contracture of the left ventricle | Irreversible contraction of the left ventricle of the heart as a complication seen in the early period of cardiopulmonary bypass and now avoided by appropriate cardioplegic solutions. Synonym: myocardial rigor mortis, stone heart. (05 Mar 2000) |
| oblique vein of left atrium | A small vein on the posterior wall of the left atrium which merges with the great cardiac vein to form the coronary sinus; it is developed from the left common cardinal vein, and occasionally persists as a left superior vena cava. Synonym: vena obliqua atrii sinistri, Marshall's oblique vein. (05 Mar 2000) |
| oesophageal branches of the left gastric artery | <anatomy, artery> Ascends through oesophageal hiatus of diaphragm to supply lowermost (cardiac) oesophagus; anastomosis: oesophageal branches of thoracic aorta. Synonym: rami oesophageales arteriae gastricae sinistrae. (05 Mar 2000) |
| transverse part of left branch of portal vein | <anatomy, vein> The long unbranched portion of the left branch of the portal vein. Synonym: pars transversa rami sinistri venae portae hepatis. (05 Mar 2000) |
| umbilical part of left branch of portal vein | <anatomy, vein> The highly branched part of the left branch of the portal vein; the round and venous ligaments attach to this part. Synonym: pars umbilicalis rami sinistri venae portae hepatis. (05 Mar 2000) |
| fold of left vena cava | A pericardial fold lying between the left oblique vein of the atrium and the left superior pulmonary vein containing the obliterated remains of the left superior vena cava. Synonym: plica venae cavae sinistrae, Marshall's vestigial fold, vestigial fold. (05 Mar 2000) |
| left | Of or pertaining to that side of the body in man on which the muscular action of the limbs is usually weaker than on the other side; opposed to right, when used in reference to a part of the body; as, the left ear. Also said of the corresponding side of the lower animals. Left bank of a river, that which is on the left hand of a person whose face is turned downstream. Left bower. See Bower. Left center, the members whose sympathies are, in the main, with the members of the Left, but who do not favor extreme courses, and on occasions vote with the government. They sit between the Center and the extreme Left. Over the left shoulder, or Over the left, an old but still current colloquialism, or slang expression, used as an aside to indicate insincerity, negation, or disbelief; as, he said it, and it is true, over the left. Origin: OE. Left, lift, luft; akin to Fries. Leeft, OD.lucht, luft; cf. AS.left (equiv. To L. Inanis), lyftadl palsy; or cf. AS.lf weak. Source: Websters Dictionary (01 Mar 1998) |
| left atrial pressure | <radiology> 15-20 mm Hg redistribution 20-25 interstitial oedema 25-30 airspace oedema (12 Dec 1998) |
| left atrioventricular valve | <anatomy, cardiology> The heart valve that divides the left atrium and left ventricle. During left atrial contraction, the mitral valve opens to allow blood to flow into the left ventricle. Upon closure, the mitral valve prohibits the regurgitation of blood back into the left atrium. The mitral valve is the only heart valve that has only 2 valve cusps (all others have 3). (13 Nov 1997) |
