| 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) |
| left atrium | <anatomy> The thin-walled chamber of the heart which pumps blood into the left ventricle for ejection into the systemic circulation. (27 Sep 1997) |
| left auricular appendage | The small conical projection from the left atrium of the heart. Synonym: auricula sinistra, left auricular appendage. (05 Mar 2000) |
| left axis deviation | A mean electrical axis of the heart pointing to -30 |
| left branch | Of a pair of branches, the branch passing to the left side of the body, to the left member of a bilateral pair of structures, or to the left portion of an unpaired structure; the other member of the pair being a right branch. Synonym: ramus sinister. (05 Mar 2000) |
| left colic artery | <anatomy, artery> Origin, inferior mesenteric; distribution, descending colon and splenic flexure; anastomoses, middle colic, sigmoid. Synonym: arteria colica sinistra. (05 Mar 2000) |
| left colic flexure | The bend at the junction of the transverse and descending colon. Synonym: flexura coli sinistra, splenic flexure. (05 Mar 2000) |
| left colic lymph nodes | Small nodes along the left colic artery and its branches that drain the left flexure and upper part of the descending colon; efferent vessels pass to the inferior mesenteric nodes. Synonym: nodi lymphatici colici sinistri. (05 Mar 2000) |
| left colic vein | <anatomy, vein> A tributary of the inferior mesenteric vein that accompanies the left colic artery and drains the left flexure and descending colon. Synonym: vena colica sinistra. (05 Mar 2000) |
| left coronary artery | <anatomy, artery> Origin, left aortic sinus; distribution, it divides into two major branches, an anterior interventricular which descends in the anterior interventricular sulcus, and a circumflex branch which passes to the diaphragmatic surface of the left ventricle; gives atrial, ventricular, and atrioventricular branches. Synonym: arteria coronaria sinistra. (05 Mar 2000) |
| left coronary artery branches | <radiology> Left anterior descending (LAD) artery, diagonal branches, septal branches (short br. at 90' angle), left circumflex artery (LCA), obtuse marginal branches (12 Dec 1998) |
| left coronary vein | <anatomy, vein> Begins at the apex of the heart (where it anastomoses with the middle cardiac vein), runs first with the anterior interventricular artery as it ascends the anterior interventricular groove, then turns to the left as it approaches or reaches the coronary groove to run with the circumflex branch of the left coronary artery; it merges with the oblique vein of the left atrium to form the coronary sinus. Synonym: vena cordis magna, left coronary vein, vena cardiaca magna. (05 Mar 2000) |
