描述
Inclusion Criteria:
- 18 - 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 (with trans-jugular or transfemoral) access
- Subject has provided informed consent and agrees to return for all required post-procedure follow-up visits
Exclusion Criteria:
- Estimated life expectancy of less than 12 months
- PVR >5 Wood units
- Echocardiographic evidence of severe right ventricular dysfunction
- Severe aortic, mitral and/or pulmonic valve stenosis and/or regurgitation requiring treatment
- Presence of significant congenital heart disease including but not limited to hemodynamically significant atrial septal defect, RV dysplasia, and arrhythmogenic RV.
- Any percutaneous cardiovascular intervention, cardiovascular surgery, or carotid surgery, within last 30 days. Implant or revision of any rhythm management device (CRT or CRT-D) or implantable cardioverter-defibrillator or leadless pacemaker within 90 days prior to the study procedure
- 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.
- Bleeding disorders including thrombocytopenia or platelet count <70,000 mm3 or thrombocytosis (platelet count >700,000 /mm3)
- 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
- 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.
- Left ventricular ejection fraction (LVEF) < 30%
- Contraindication or inability to complete transesophageal or intracardiac echocardiogram
