怎样选择瓣膜 机械瓣与生物瓣各有什么优缺点 孟自力 河北省胸科医院

怎样选择瓣膜 机械瓣与生物瓣各有什么优缺点 孟自力 河北省胸科医院 瓣膜分为两类，一种是机械瓣，一种是生物瓣。机械瓣的优点是持久耐用，缺点是需要长期服用华法林。生物瓣的优点正好跟它相反。生物瓣的优点不用长期服用华法林，但是缺点是适用期较短，一般10到20年会出现问题。所以选择瓣膜时，一般60岁以上的患者选用生物瓣，年轻的选用机械瓣。另一个问题，机械瓣相对较便宜，大概费用是1万到2万块钱。而生物瓣一般2万到5万块钱，所以根据病人的情况进行相应的选择。有关机械瓣术后华法林用法，会根据它的重凝血时间进行相应的调整，一般早期需要两三天查一次重凝血时间，根据重凝血时间中的国际比值进行相应的华法林的调整。而生物瓣只需要服用三个月，三个月以后就可以不再服用华法林，但是由于它是生物瓣，使用期比较短，一般需要一两年查一次心脏超声，看瓣膜的退化情况。一般情况下能耐用15年到20年 How to choose mechanical valve and biological valve There are two types of valves, One is mechanical valve, One is biological valve. The advantage of the mechanical flap is that it is durable, The disadvantage is that warfarin needs to be taken for a long time. The advantages of biological valve are just the opposite. The advantage of bioprosthetic valve is that it does not need to take warfarin for a long time, But the disadvantage is that the application period is short, Generally, problems will occur in 10 to 20 years. So when choosing valves, In general, patients over 60 years old choose bioprosthetic valve, Young choose mechanical valve. Another question, The mechanical flap is relatively cheap, The cost is about 10000 to 20000 yuan. And biological valve is usually 20000 to 50000 yuan, So according to the patient's situation to make the corresponding choice. About the usage of warfarin after mechanical valve operation, It will be adjusted according to its time of recoagulation, In the early stage, two or three days are needed to check the time of heavy coagulation, Warfarin was adjusted according to the international ratio of the time of heavy coagulation. The bioprosthetic valve only takes three months, You can stop taking warfarin in three months, But because it's a biological valve, The service life is relatively short, It usually takes one or two years to get a cardiogram, Look at the degeneration of the valve. Generally, it can last 15 to 20 years
