Prospective Randomized On-X Versus SJM Evaluation Trial (PROSE)

May 23, 2021 updated by: On-X Life Technologies, Inc.

Thromboembolic Related Complications in a Randomized Trial of Previous and Current Generation Mechanical Valve Prostheses

The study hypothesizes that rate of thromboembolic complications of the On-X prosthesis is reduced as compared to the SJM prosthesis.

Study Overview

Detailed Description

The study is a multi-centre, randomized trial that will sequentially enroll up to 500 eligible patients in each group from up to 10 participating study centres internationally to test the hypothesis.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. The patient requires an isolated mitral or isolated aortic valve replacement. (Patients undergoing coronary artery bypass and / or concomitant repair of mitral or tricuspid valves are eligible.)
  2. The patient is a candidate for receipt of a mechanical heart valve.
  3. The patient (or legal guardian) has signed a study-specific informed consent form agreeing to the randomization, data collection and follow-up requirements.
  4. The patient can be having a re-operative procedure, so long as the previous prosthetic valve is explanted and the patient does not become a double valve implantation patient.

Exclusion Criteria:

  1. The patient is not a candidate to receive a mechanical heart valve.
  2. The patient already has a prosthetic valve other than the valve(s) being replaced at this time.
  3. The patient requires a tricuspid valve replacement.
  4. The patient is enrolled in another investigative study or trial.
