This study is a multi-center, prospective, non-randomized, observational study. The objectives of this study are to confirm the clinical safety and efficacy of the SJM Epic valve.

Condition Intervention
Valvular Heart Disease Device: EPIC

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Observational, Prospective Evaluation of the SJM Epic Valve

Further study details as provided by St. Jude Medical:

Primary Outcome Measures:
  • Adverse effect rates [ Time Frame: Ongoing ]
  • Clinical status as indicated by NYHA functional classification [ Time Frame: At required follow-up visits ]
  • Hemodynamic performance [ Time Frame: At required follow-up visits ]

Enrollment: 761
Study Start Date: January 2003
Study Completion Date: September 2008
Primary Completion Date: March 2006 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: EPIC
    Surgical replacement of a diseased, damaged, or malfunctioning native or prosthetic aortic and/or mitral heart valves
Detailed Description:

This study is a multi-centered, multi-country, prospective, non-randomized, observational study, without concurrent or matched controls, conducted under a common protocol. Bayesian methods will be used for the design and analysis of this study. The Bayesian model will determine if the data for the valve configurations are poolable. Bayesian methods also provide a means of determining the appropriate stopping time for the study based on the amount of information generated. The objectives of this study are to confirm the clinical safety and efficacy of the SJM Epic Valve by establishing the following:

  • adverse effect rates
  • clinical status as indicated by NYHA functional classification
  • hemodynamic performance
