| 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 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) |
