• Moderate or greater tricuspid valve stenosis.
• Severe aortic, mitral and/or pulmonic valve stenosis and/or regurgitation
• Pacemaker or implantable cardioverter-defibrillator (ICD) leads that would prevent appropriate placement of the investigational device.
• Need for concomitant surgical or interventional procedure, known at the time of screening (e.g., CABG, Atrial Septal Defect (ASD) repair).
• Ejection Fraction (EF) \<25%

• Severe respiratory instability with continuous use of home oxygen
• Severe right ventricular dysfunction
• Untreated clinically significant coronary or carotid artery disease requiring revascularization surgical or interventional PCI.
• Stroke or transient ischemic event within 90 days prior to the index procedure
• Acute myocardial infarction within 30 days before the index procedure
• Renal insufficiency (eGFR \<25 ml/min) or currently on chronic dialysis
• Active endocarditis within 6 months of the index procedure
