|---|---|
| ASIS | anterior superior iliac spine |
| ASS | acute serum sickness; acute spinal stenosis; anterior superior spine; argininosuccinate synthetase |
| CSMAP | celiac-superior mesenteric artery portography |

| left ventricle | <anatomy> The muscular chamber of the heart which accepts blood from the left atrium and ejects it into the aorta to the systemic circulation. (27 Sep 1997) |
|---|---|
| left-ventricular assist device | Mechanical pump inserted at some point in the circulation to parallel the activity of the left ventricle and thereby reduce its load. (05 Mar 2000) |
| left ventricular ejection time | The time measured clinically from onset to incisural notch of the carotid or other pulse; properly the time of ejection of blood from the left ventricle beginning with aortic valve opening and ending with aortic valve closure. (05 Mar 2000) |
| left ventricular failure | <cardiology> A disorder where the left side of the heart fails to pump blood effectively. This results in a back flow (and pressure) and congestion of blood into the lungs. The causes of this condition include, valvular heart disease, cardiomyopathy, anaemia, hyperthyroidism, atrial myxoma, drug toxicity and congenital heart disease. Risk factors include diabetes, alcoholism, obesity and smoking. Symptoms include increasing shortness of breath with activity and while lying flat. Other symptoms include cough, palpitations, fatigue, decreased urine production and waking in the middle of the nigh with difficulty breathing. Complications include pulmonary oedema, arrhythmias and pleural effusion. (27 Sep 1997) |
| left ventricular hypertrophy | <radiology> Coarctation, aortic stenosis (12 Dec 1998) |
| left ventricular myomectomy | Resection of myocardial tissue used in cases of idiopathic hypertrophic subaortic stenosis. (05 Mar 2000) |
| left ventricular volume overload | <radiology> VSD, patent ductus arteriosus, mitral incompetence, aortic incompetence (12 Dec 1998) |
| ligament of left vena cava | The obliterated left common cardinal vein; it extends from the left brachiocephalic vein to the oblique vein of the left atrium. Synonym: ligamentum venae cavae sinistrae. (05 Mar 2000) |
| lingula of left lung | An inferomedial projection from the anterior aspect of the upper lobe of the left lung which bounds the cardiac notch inferiorly. Synonym: lingula pulmonis sinistri. (05 Mar 2000) |
| aditus glottidis superior | Portion of the cavity of the larynx between the vestibular and vocal folds, with which the ventricles communicate. Synonym: aditus glottidis superior. (05 Mar 2000) |
| angulus superior scapulae | Formerly named the medial angle, it lies at the junction of the superior and medial borders of the bone. Synonym: angulus superior scapulae. (05 Mar 2000) |
| ankyloglossia superior syndrome | <syndrome> A congenital condition in which the tongue adheres to the hard palate; no evidence of genetic factors. (05 Mar 2000) |
| anterior superior alveolar arteries | Origin, infraorbital artery within intraorbital canal; distribution, via anterior alveolar canals to upper incisors and canine teeth, mucus membrane of maxillary sinus. Synonym: arteriae alveolares superiores anteriores, anterior superior dental arteries. (05 Mar 2000) |
| anterior superior alveolar branches of infraorbital nerve | <anatomy, nerve> The branches of the superior alveolar nerve that supply the incisors, canines, premolars, and first molar by their contributions to the superior dental plexus. Synonym: rami alveolares superiores anteriores nervi infraorbitalis. (05 Mar 2000) |
| anterior superior dental arteries | Origin, infraorbital artery within intraorbital canal; distribution, via anterior alveolar canals to upper incisors and canine teeth, mucus membrane of maxillary sinus. Synonym: arteriae alveolares superiores anteriores, anterior superior dental arteries. (05 Mar 2000) |
