Some of the mechanical and biological problems surrounding the use of fresh allograft inverted aortic valves as mitral valve substitutes are described. Certain aspects of the problem have been studied expzrimentally. In three sheep 'fresh' aortic valve allografts were-inserted, using cardio-pulmonary bypass, into the main pulmonary artery, and were observed from 5 to 7 months after operation. T...

aim : this study evaluated the association between serum endothelin- 1 level and symptoms, clinical examination, laboratory and cardio-respiratory parameters, in patients with cirrhosis compared to controls. background : cirrhosis is associated with significant portal, pulmonary and systemic vascular abnormities. recent studies have suggested that endothelin -1 may have a significant role in th...

In the present study, a retrospective analysis of the trends and factors affecting blood glucose and blood lactate levels was carried out for non-diabetic adult patients who had undergone coronary artery bypass graft (CABG) surgery. Between October 2009 and October 2011, 200 non-diabetic adult patients undergoing CABG surgery were examined. Glucose and lactic acid levels were observed successiv...

Diastolic Dysfunction (DD) is a well-described component of coronary artery disease (CAD), and is common among cardiac surgery patients.Managed care pressures have intensified recent trends of “fast-tracking” coronary artery bypass grafting (CABG) patients, leading to more reliance on volatile anesthetic gases such as isoflurane. However, volatile anesthetics are known to have the side-effect o...

Coronary artery bypass grafts relieve angina and prolong some patients' lives with an operative mortality of 1-4%. The grafting requires temporary artificial maintenance of the blood's circulation and oxygenation with cardiopulmonary bypass. In the United States some 200 000 people yearly have a coronary artery bypass graft-six times as many in relation to the population as in Britain. The grea...
