研究疾病:

先天性心脏病心脏外科纠治术后并发严重肺动脉瓣反流  

Target disease:

Severe pulmonary valve regurgitation following surgical correction of congenital heart disease

研究疾病代码:

Target disease code:

研究类型:

干预性研究

Study type:

Interventional study

研究所处阶段:

治疗新技术临床试验 

Study phase:

New Treatment Measure Clinical Study

研究设计:

单臂 

Study design:

Single arm 

研究目的:

鉴于VenusP Valve经导管人工肺动脉瓣膜系统的注册性临床研究已经完成入组,且目前中国市场上并没有已经获批上市的经导管人工肺动脉瓣膜置换系统,为了满足患者的救治需求,开展此新技术临床试验,同时也将进一步对试验产品进行安全性和有效性的评价。  

Objectives of Study:

In view of the fact that the registration clinical study of VenusP Valve has been completed, and there is no approved pulmonary valve replacement system on the Chinese market at present, in order to meet the needs of patients, clinical trials of this new technology will be carried out, and the safety and effectiveness of the test products will be further evaluated.
