Who can join

Age: 60 and older, up to 90. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• 60 - 90 years of age at the time of the study procedure
• Symptomatic tricuspid regurgitation despite being adequately treated with optimal medical therapy by the Local Heart Team for at least 30 days prior to the time of study consent.
• Severe, massive or torrential tricuspid regurgitation determined by qualifying transthoracic echocardiogram (TTE) and/or transesophageal echocardiogram (TEE) using the 5-grade classification.
• Candidate felt suitable for transcatheter tricuspid valve replacement as determined by the local heart team and confirmed by the patient selection committee. For patients with pre-existing trans-tricuspid pacemaker or ICD leads, the local heart team shall include an electrophysiologist.
• Anatomically suitable for the Laplace TTVR system including trans-jugular access 6 Subject or legally authorized representative has provided informed consent and agrees to return for all required post-procedure follow-up visits

You may not qualify if…

• 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
• New or untreated right heart chamber or/and superior vena cava intracardiac mass, thrombus, or vegetation
• Presence of significant congenital heart disease including but not limited to hemodynamically significant atrial septal defect, RV dysplasia, and arrhythmogenic RV.
• Untreatable hypersensitivity or contraindication to any of the following: Aspirin, and Clopidogrel or Ticlopidine, Heparin, and Bivalirudin, Warfarin, or DOAC, Nitinol Alloys.
• Severe renal insufficiency defined as eGFR <25 mL/min or requiring chronic renal replacement therapy at the time of screening committee review.
• Current history (within last 5 years) of illicit drug use.

• Need for emergent, urgent or planned surgery or intervention within 30 days following the study procedure. Planned or scheduled cardiac surgery within next 12 months.
• Stroke or other major cerebrovascular event within 90-days prior to index procedure
• Untreated clinically significant coronary artery disease requiring revascularization, recent (within last 30 days) acute coronary syndrome or myocardial infarction.
• Active or recent GI bleed within 30 days prior to study procedure or patients Contraindicated for oral anticoagulation therapy
• Bleeding disorders including thrombocytopenia or platelet count <70,000 mm 3 or thrombocytosis (platelet count >700,000 /mm 3)
• Transfusion dependent chronic anemia with Hb <9/dL
• Current or planned pregnancy within next 12 months for women of childbearing potential
• Active or recent endocarditis within last 90 days or, sepsis/ other systemic infection requiring oral or intravenous antibiotics within last 30 days
• Prior tricuspid repair or tricuspid replacement or other device that would interfere with successful deployment or functioning of Laplace tricuspid valve.
• Participation in another pre-market investigational device study or investigational drug study for a cardiac related drug
• Presence of other anatomic or comorbid conditions, or other medical, social, or psychological conditions that, in the investigator's opinion, could limit the subject's ability to participate in the clinical investigation or to comply with follow-up requirements. Any patient considered to be vulnerable.
