国家心血管病中心、阜外医院昨日召开新闻发布会，该院近日成功为两例不能进行外科手术治疗的严重主动脉瓣狭窄患者通过“不开胸”的方式置入了国产的主动脉瓣装置。此前，我国还没有经导管置入的主动脉瓣上市。

National cardiovascular disease center/Fortune recourse international hospital held a press conference yesterday,The hospital recently for two cases of success can not carry out of surgical treatment of severe aortic stenosis patients through"Don't open the chest"In the way of homebred aortic valve device.after,China is still not the catheter placement aortic listed.

　　国家心血管病中心吴永健介绍了这两例患者的基本情况，患者的年龄分别为84岁和79岁。手术是在清醒状态下，经股动脉插入导管，持续了1.5小时。患者术后第二天就开始下地活动，症状消失，术后一周出院，心脏超声检查发现置入的人工瓣膜工作状态良好。

National cardiovascular disease center WuYongJian introduces the two basic situation of the patients,The age of the patients respectively for 84 years and 79 years old.Surgery is in the waking state,Via femoral artery insert catheter,For 1.5 hours.Postoperative patients with the second day began to earth activities,Symptoms disappear,A week after the hospital,Heart ultrasonic inspection found that the artificial valve work in good condition.

　　据国家心血管病中心高润霖院士介绍，此次置入的装置是杭州启明医疗公司生产的Venus A-Valve?，这种装置是一种自膨胀式的生物膜叶瓣。与欧美同类产品比较，在设计上更加合理，在操作上更加简便。另外，在操作过程中，一旦发现位置偏移，可以回收并重新定位，是第一款应用于临床的可回收的导管瓣膜系统。

According to the state of cardiovascular disease center GaoRunLin academician is introduced,The placement of the device is hangzhou open minded medical company produces the Venus A - Valve?,This device is a kind of self expansion of biological membrane leaf disc.And Europe and the United States similar products compare,On the design more reasonable,In the operation more simple.In addition,In the operating process,Once found position migration,Can be recycled and repositioned,The first paragraph is applied to clinical recycled catheter valve system.

　　国家心血管病中心杨跃进教授指出，我国人口老龄化趋势明显，心血管危险因素流行，发生瓣膜退行性病变的患者有逐年增多的趋势。根据国外的资料，年龄大于65岁的老年人中，有2%～7%的人存在瓣膜病。对于严重主动脉瓣狭窄以往只能外科换瓣手术治疗，但在高龄患者多合并其他系统脏器的严重疾病，因不能耐受外科手术，而失去治疗机会，药物治疗效果差，死亡率极高。

National cardiovascular disease center YangYueJin professor noted that,The population aging in our country is the tendency to be obvious,Cardiovascular risk factors pop,Happen valve degenerative diseases of patients have increased year by year the trend.According to the foreign material,Older than 65 years of age in the elderly,With 2% ~ 7% of people exist valvular disease.For severe aortic stenosis in the past can only surgery in valve surgery,But at a ripe old age patient merges other system of the serious disease,Because can't tolerate surgery,And lose treatment opportunity,Drug therapy effect is poor,High mortality rate.

　　欧美已经从2002年就开始推进经导管置入的主动脉瓣，这项技术堪称心血管介入领域的第四次革命。据国外进行的对不能接受外科换瓣手术的严重主动脉瓣狭窄患者的随机对照研究，经导管主动脉瓣置入治疗与标准治疗相比，一年死亡危险降低46%(死亡率绝对值降低20%)。目前全球已有超过5万例患者从该治疗中获益。(李景仁)

Europe and the United States have from 2002 began to push the catheter placement of the aortic valve,The technology in the field of cardiovascular intervention is the fourth revolution.According to the overseas to can't accept surgery in valve surgery patients with severe aortic stenosis randomized controlled studies,The catheter aortic valve placement treatment compared with standard therapy,A 46% reduction in the risk of death(Mortality absolute value reduced by 20%).The world more than 50000 patients benefit from the treatment.(LiJingRen)
