A mechanical valve usually lasts decades. If the coumadin level is not just right, the valve can clot off, though this usually produces dramatic (often fatal) symptoms, not just a slow deterioration. However, it is possible that he has some other problem, such as a heart arrhythmia. In any case, an evaluation by his cardiologist makes sense, though he may need more than just an adjustment of his coumadin dose.
