Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to investigate whether the Silzone coated sewing cuff reduces the incidence of prosthetic valve endocarditis (PVE).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of this study is to investigate whether the Silzone coated sewing cuff reduces the incidence of prosthetic valve endocarditis. The null and alternative hypotheses of this study are:

* Ho: Patients receiving SJM Masters Series valves with Silzone coating will have an equal incidence of PVE when compared to those receiving the conventional cuff.
* Ha: Patients receiving SJM Masters Series valves with Silzone coating will have a reduced incidence of PVE when compared to those receiving the conventional cuff.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* The patient requires an isolated mitral, isolated aortic, or double (aortic and mitral) valve replacement
* The patient is a candidate to receive an SJM (St. Jude Medical) Masters Series valve(s) with either the conventional cuff or the cuff with Silzone coating
* The patient (or legal guardian) has signed a study-specific consent form agreeing to the randomization, data collection, and follow-up requirements

Exclusion Criteria

* The patient has a medical condition which contraindicates implantation of the SJM Masters Series with Silzone coating
* The patient already has a prosthetic valve other than the valve being replaced at this time
* The patient requires a tricuspid valve replacement
