First in Human Experience of the St. Jude Medical TAVI Valve and Delivery System
The purpose of this first-in-human study is to assess the technical feasibility, deployment characteristics, and safety of the 23mm SJM Transfemoral Transcatheter Heart Valve and delivery system in subjects with severe symptomatic aortic stenosis (AS). This is a single center, prospective, non-randomized, first-in-human investigational study without concurrent or matched controls.
Full Title of Study: “First In Human Experience and Assessment of the 23mm SJM Transcatheter Aortic Valve Implant and the SJM TAVI Transfemoral Delivery System (SJM TAVI FIH)”
- Study Type: Interventional
- Study Design
- Allocation: N/A
- Intervention Model: Single Group Assignment
- Primary Purpose: Treatment
- Masking: None (Open Label)
- Study Primary Completion Date: October 2011
Data will be collected at baseline, procedure, discharge (date of hospital discharge or 7 days post-implant, whichever occurs first), 30 days post implant, 3 months post implant, 6 months post implant, and 12 months post implant.
- Device: Transcatheter Aortic Valve Implantation (TAVI)
- Placement of the SJM TAVI aortic valve with a transfemoral delivery system.
Arms, Groups and Cohorts
- Experimental: Subjects receiving TAVI valve
Clinical Trial Outcome Measures
- Assessment of Technical Feasibility and Device Deployment Characteristics
- Time Frame: At time of procedure
- Evaluate the technical feasibility and device deployment characteristics (observed at procedure) by: The ability for the valve to be deployed at the desired location The ability to complete the full procedure Quantification of the time from delivery system entry to a fully deployed and functional valve
- Quantification of SAEs Reported (Device Related or Procedure Related)
- Time Frame: Through 12 months post implantation
- Evaluate the safety of the 23mm SJM Transcatheter Aortic Heart Valve and transfemoral delivery system by: Summarizing the SAEs observed at procedure that are device or procedure related Summarizing the SAEs observed during the study
