| ventricular dysfunction, left | A condition in which the left ventricle of the heart exhibits a decreased functionality. This decreased function could lead to congestive heart failure or myocardial infarction, among other cardiovascular diseases. Diagnostic measurements that indicate this condition include a diminished ejection fraction and a depressed level of motility of the left ventricular wall. (12 Dec 1998) |

| ventricular dysfunction | A condition in which the ventricles of the heart exhibit a decreased functionality. (12 Dec 1998) |

| ventricular dysfunction, right | A condition in which the right ventricle of the heart exhibits a decreased functionality. This decreased function could lead to congestive heart failure or myocardial infarction, among other cardiovascular diseases. Diagnostic measurements that indicate this condition include a diminished ejection fraction and a depressed level of motility of the right ventricular wall. (12 Dec 1998) |
| aortico-left ventricular tunnel | Congenital connection between the aorta above exit of coronary arteries and the left ventricle. (05 Mar 2000) |
| 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) |
| 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) |
| 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) |
| papillary muscle dysfunction | Impaired function of a papillary muscle, usually due to ischemia or infarction, with resulting incompetence of the mitral valve. Synonym: papillary muscle syndrome. (05 Mar 2000) |
| phagocyte bactericidal dysfunction | Disorders in which phagocytic cells cannot kill ingested bacteria; characterised by frequent recurring infection with formulation of granulomas. (12 Dec 1998) |
| phagocyte dysfunction | Disorder in which the ability of the phagocyte to engulf and ingest particles may be impaired. (05 Mar 2000) |
| phagocytic dysfunction disorders immunodeficiency | Suppression in number or function of phagocytic cells such as in chronic granulomatous disease. Synonym: phagocytic dysfunction disorders immunodeficiency. Origin: L. Phagedaena, Gr Phago, To eat. (05 Mar 2000) |
