Safety and Feasibility Study: Transcatheter Valve Repair in Severe Symptomatic Functional Tricuspid Regurgitation

Exclusion Criteria27

• Estimated life expectancy of less than 12 months
• Systolic pulmonary artery pressure (sPAP) \>70 mmHg as assessed by TTE or right heart catheterization
• Acutely decompensated, defined as hypotension with SBP \<90 mmHg, use of hemodynamic support devices or inotropes or uncontrolled arterial hypertension with SBP \>180 mmHg within 30 days of the study procedure
• Severe COPD dependent on home oxygen or chronic home oxygen use
• Echocardiographic evidence of severe right ventricular dysfunction
• Severe aortic, mitral and/or pulmonic valve stenosis and/or regurgitation requiring treatment (prior transcatheter or surgical treatment allowable)
• Any condition that would interfere with the procedure, such as prior tricuspid valve repair, tricuspid valve leaflet anatomy which may preclude device implantation, pacemaker or Implantable Cardioverter Defibrillator (ICD) leads that would prevent appropriate placement or visualization of implant, Ebstein Anomaly (normal annulus position, but valve leaflets attached to walls and septum of the right ventricle)
• Tricuspid valve stenosis defined as a tricuspid valve orifice of ≤1.0 cm2 and/or mean gradient of ≥5 mmHg
• New or untreated right heart chamber and/or superior vena cava intracardiac mass, thrombus, or vegetation
• Degenerative tricuspid or rheumatic tricuspid valve disease
• Any percutaneous cardiovascular intervention, cardiovascular surgery, or carotid surgery within 30 days of the study procedure
• Implant or revision of any rhythm management device (CRT or CRT-D, ICD, or leadless pacemaker) within 90 days prior to the study procedure
• Known need for emergent, urgent, or planned surgery or intervention within 30 days following the study procedure, or planned or scheduled cardiac surgery within 12 months following the study procedure
• Stroke or other major cerebrovascular event within 90 days prior to the study procedure
• Untreated clinically significant coronary artery disease requiring revascularization, recent (within 30 days of the study procedure) acute coronary syndrome or myocardial infarction
• Active or recent GI bleed within 30 days prior to the study procedure, or patients contraindicated for oral anticoagulation therapy
• Bleeding disorders including thrombocytopenia (platelet count \<70,000 mm3) or thrombocytosis (platelet count \>700,000 mm3)
• Transfusion-dependent chronic anemia with Hb \<9/dL
• Current or planned pregnancy within 12 months of the study procedure for women of childbearing potential
• Active or recent endocarditis within 90 days of the study procedure, or sepsis/other systemic infection requiring oral or intravenous antibiotics within 30 days of the study procedure
• Prior tricuspid repair or tricuspid replacement or prosthetic implant that would interfere with successful deployment or functioning of the Tangent Implant
• Participation in another pre-market investigational device study or investigational drug study (for a cardiac-related drug)
• Presence of other anatomic or co-morbid conditions, or other medical, social, or psychological conditions that, in the investigator's opinion, could limit the subject's availability to participate in the clinical investigation or to comply with follow-up requirements
• Any patient considered to be vulnerable
• Left ventricular ejection fraction (LVEF) \<30%
• Deep vein thrombosis or pulmonary embolism within 6 months of the study procedure
• Child-Pugh C cirrhosis
