New heart valve offers hope for patients with severe leaky heart

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients with symptomatic tricuspid regurgitation (TR), graded as severe or greater (accord. to TR 5-Tier Grading System TVARC) * Patients with TR leading to NYHA class II, III or IV or clinical signs of right heart failure * Patients suitable for implantation of the TRICENTO G2 Bioprosthesis according to anatomical and clinical criteria assessed by computed tomography, echocardiography and/or right heart catheterization (confirmed by a heart team) * Patients receiving optimal medical treatment for underlying diseases * Patients being able to give informed consent * Patients empowered and willing to comply with the study procedures Exclusion Criteria: * Superior vena cava diameter \< 22.9 mm or \> 37.1 mm (perimeter derived) * Inferior vena cava diameter \< 27.9 mm or \> 42.9 mm (perimeter derived) * Right atrium cavity height \< 55 mm or \> 80 mm (direct path between caval ostia) * Peak right atrial pressure \> 50 mmHg * Systolic pulmonary artery pressure (sPAP) \> 60 mmHg * Pulmonary Vascular Resistance \> 3 Wood units * Vascular conditions that do not allow for insertion and access routing of the 26 Fr Delivery System to the intended implantation site * Known hypersensitivity, allergy or contraindication to the device's materials, e.g. Nitinol * Echocardiographic evidence of intra-cardiac thrombus or vegetation * Relevant tricuspid valve stenosis (e.g. determined by a mean diastolic transvalvular gradient \> 5 mmHg at a normal heart rate) * RV dysfunction determined by multiple of the following * TAPSE \< 10mm * RVOT VTI \< 10 cm * TASV/S' \< 11.5 cm/s * RV FAC \< 30 % * RV EF \< 35 % * Severe uncontrolled hypertension (systolic BP ≥ 180 mmHg and/or diastolic BP ≥ 110 mmHg) * LV function defined by LVEFbp \< 25 % * Indication for intervention for any of the other heart valves or for open cardiac surgery * Any PCI or transcatheter valvular intervention within 30 days prior to the index procedure or planned 3 months post the index procedure * Myocardial infarction within the 30 days prior to the index procedure * Evidence of a present thrombosis of the lower venous system * Medical devices present in the intended implantation site that are expected to interfere with the access, proper deployment and/or function of the prosthesis * Evidence of active endocarditis or other acute infections * Known hypersensitivity or contraindication to anticoagulation, anti-platelet medication, or contrast media, which cannot be adequately pre-medicated * Patients on chronic dialysis * Thrombophilia * Bleeding diathesis or coagulopathy * Women of childbearing potential, defined as females who have experienced menarche and who are not permanently sterile or not postmenopausal (≥12 consecutive months without menses without an alternative medical cause) * Patients with any known life-threating, non-cardiac disease that will limit life expectancy of the patient to less than one year
