Tissue Heart Valve Replacement at BSMMU- Initial Experience with Two Cases

Abstract

Research on prosthesis to replace diseased heart valves began almost simultaneously with mechanical valves which are durable but with inherent thromboembolic complication requiring life-long anticoagulant therapy and tissue valves which are more prone to structural failure but free from thromboembolic complication. Tissue valves are more useful in females of reproductive age desiring a child, male patients older than 60 years of age and female patients over 55 years of age, patients having chronic liver disease, history of stroke, bleeding disorder and in presence of infective endocarditis. Gluteraldehyde fixation at low pressure with removal of maximal amount of phospholipid have increased the durability of tissue valves in recent years. Considering the better quality of life with tissue valve the trend is shifting towards using it more frequently around the world. Recently two heart valve replacement operations using bovine perimount pericardial valve were done in the department of cardiac surgery, BSMMU, one in aortic position another in mitral position, both in females of reproductive age desiring children.The operations were technically demanding but the outcomes were uneventful. Tissue heart valve replacement is a safe procedure and can be useful in female of child bearing age desiring children.
