简要总结
A single arm, prospective multicenter non-randomized pivotal clinical trial evaluating the Edwards SAPIEN XT™ transcatheter heart valve (model 9300TFX), NovaFlex™ transfemoral delivery system, Ascendra2™ transapical delivery system and crimper accessories. The trial includes a premarket pivotal cohort to evaluate the system performance as well as a post market clinical follow-up phase involving long term follow-up of all patients to evaluate the safety of investigational devices up to 5 years.
详细描述
Purpose: To evaluate the safety and efficacy of THV-9300 for patients who have severe symptomatic aortic stenosis attributed to calcification and degeneration of a valve leaflet and for whom undergoing a surgery safely would be difficult.
Follow-up: Subject data collection will include clinical information at baseline and during the index procedure. Subjects will undergo clinical follow-up at discharge, 30 days, 6 months and annually for 5 years.

结局指标
主要结局
Improvement of the AVA and NYHA Functional Classification
时间窗: 6 Months
Improvement of the aortic valve area (AVA) and New York Heart Association (NYHA) functional classification from baseline to 6 months after the procedure. NYHA functional classification of heart failure based on how much a patient is limited during physical activity. The rating ranges from I-IV, with the lowest (I) as no limitations and the highest (IV) unable to carry on any physical activity without discomfort. The AVA at 6 months \> 1.0 cm2 indicates improvement. This outcome measure shows the percentage of patients that had an improvement in both NYHA Class and AVA.
