    <Internation Icirculation>:As a promising new treatment for patients with aortic-valve disease，what are the advantages of transcatheter aortic valve implantation（TAVI）compared with traditional surgery and conservative management? And what are the major shortcomings?

 《国际循环》：经导管主动脉瓣置换术（TAVI）是主动脉瓣疾病患者有前景的治疗手段。请问TAVI与传统外科手术和保守治疗相比有哪些优势？主要有哪些缺点？
 

    Prof Schuler: The major advantage of a percutaneous treatment is the lack of invasiveness. We are talking about aged patients， usually above the age of eighty years， and many of these patients have associated comorbidities. Valve replacement by conventional surgery exposes these patients to considerable risk. We hope we can reduce this risk by percutaneous treatment. However， at this time， no randomized data is available and we are awaiting the publication of the results of the US PARTNER study， cohort A. 

    Schuler教授：TAVI的主要优势是创伤小。我们这里是说老年患者，通常年龄在80岁以上。这些患者很多有并存疾病。这些患者采用传统方法置换主动脉瓣时风险很大。我们期望能够通过采取经皮治疗降低患者的风险。但是，目前还没有来自随机试验的结果。我们正在美国的PARTNER研究队列A的研究结果发表。
