3. Severe tricuspid regurgitation associated with right ventricular dysfunction and enlargement
4. Severe mitral annular calcification
5. Severe aortic stenosis
6. Expected to require any cardiac surgery, including surgery for coronary artery disease (CAD) or valve disease within one (1) year
7. Chronic, severe, medical conditions or pathology, other than heart failure, that will prevent likely survival beyond twelve (12) months or any other medical condition that, in the judgement of the Investigator or Central Review Committee, makes the patient a poor candidate for this study
