30. Acutely decompensated heart failure (i.e. hemodynamically unstable or requiring IV inotrope ) at the time of screening

31. Severe COPD or continuous use of home oxygen

32. Currently participating in another investigational drug or device study that has not completed the primary endpoint or that clinically interferes with the endpoints of this study

33. Aortic or pulmonic valve disease requiring surgery

34. Venous peripheral anatomy unsuitable for implant delivery

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	1. Primary Performance Endpoint - Technical Success of Cardiovalve Delivery and Function in each participant	Cardiovalve Technical Success defined as: I Successful access, delivery and retrieval of the delivery system; II Successful deployment of correct positioning of the first intended implant; III Freedom from emergency surgery or reintervention related to the device or access procedure without any procedural mortality, stroke, and device dysfunction at 30-day follow-up.	30 Days
Primary	Primary Performance Endpoint - Clinical Performance - Reduction in Tricuspid Regurgitation severity measured using Echocardiography and compared to baseline	Cardiovalve Clinical Performance will be evaluated as: I The reduction in degree of tricuspid regurgitation measured immediately after the procedure compared to baseline; II The reduction in degree of tricuspid regurgitation measured at the time of discharge or 7 days post procedure, whichever comes first, in comparison with baseline; Tricuspid Regurgitation is measured using Echocardiography and is graded based on degree of severity using grading conventions from 0 to 4+.; 0 = absent; = mild; = moderate; = moderate to severe; = severe	30 Days
Primary	Primary Safety Endpoint (Patient Based) Participants Implanted without Major Device Related Adverse Events through thirty days	The ability of the Cardiovalve to be implanted without Major Device Related Adverse Events through thirty (30) days including: I Death (Cardiovascular mortality vs non-cardiovascular); II Reintervention (operative or transcatheter) due to progressive or recurrent TR or device related complications; III Disabling stroke; IV Myocardial infarction (MVARC definition); V Major access site and vascular complications; VI Fatal or life-threatening bleeding (MVARC Type III-V); VII Arrhythmia and conduction disorder requiring permanent pacing; VIII Right coronary artery occlusion requiring intervention; IX Cardiac tamponade, X Renal failure requiring dialysis	30 Days
Secondary	Secondary Performance Endpoint - Tricuspid Regurgitation Severity	Tricuspid Regurgitation is measured using Echocardiography and is graded based on degree of severity using grading conventions from 0 to 4+.; 0 = absent; = mild; = moderate; = moderate to severe; = severe	30 days, 3 months, 6 months
Secondary	Secondary Performance Endpoint - Cusp Insufficiency	Cusp Insufficiency: Change in the degree of the cusp insufficiency as assessed with echocardiography (ordinal) from a higher to a lower value	30 days, 3 months, 6 months
Secondary	Secondary Performance Endpoint - Unrestricted Movement of Cusps	Unrestricted Movement of Cusps: the percentage of medical devices with unrestricted movement of cusps after implantation as assessed with echocardiography	30 days, 3 months, 6 months
Secondary	Secondary Performance Endpoint - New York Heart Association (NYHA) functional class	NYHA function class I - IV; Higher functional class represents more severe symptoms of heart failure; NYHA Classification - The Stages of Heart Failure: Class I - No symptoms and no limitation in ordinary physical activity, e.g. shortness of breath when walking, climbing stairs etc.; Class II - Mild symptoms (mild shortness of breath and/or angina) and slight limitation during ordinary activity.; Class III - Marked limitation in activity due to symptoms, even during less-than-ordinary activity, e.g. walking short distances (20-100 m).Comfortable only at rest.; Class IV - Severe limitations. Experiences symptoms even while at rest. Mostly bedbound patients.	30 days, 3 months, 6 months
Secondary	Secondary Performance Endpoint - 6 minute walk test	6 minute walk test distance (meters)	30 days, 3 months, 6 months
Secondary	Secondary Performance Endpoint - Kansas City Cardiomyopathy Questionnaire	Kansas City Cardiomyopathy Questionnaire (KCCQ) - 23 subjective quality of life questions. Assessed before and after implantation. Scores are transformed to a range of 0-100, in which higher scores reflect better health status.; There are 3 subscales: Symptom Burden - range 0-100; Physical Limitation - range 0-100; Quality of Life - range 0-100; The total KCCQ score represents the mean (average) of the three subscale scores.	30 days, 3 months, 6 months
