TRIcvalve biCAVal Valve System for Severe Tricuspid Regurgitation (TRICAV-I)

Korábbi kezelés

• Subject had a recent MI, stroke or cardiovascular accident; underwent coronary artery bypass graft surgery, had a percutaneous coronary intervention or other major cardiovascular surgery within 90 days prior to TricValve implantation.
• Lower extremity venous thrombosis and/or the presence of an IVC filter at the time of or 6 months prior to TricValve procedure.
• Any known allergy or hypersensitivity to nitinol, bovine tissue or contrast media that cannot be adequately treated with pre-medication.
• Unable to tolerate anticoagulation/antiplatelet therapy
• Hemodynamic instability, cardiogenic shock, inotropic support, intra-aortic balloon pump or acute heart failure within 30 days prior to the TricValve procedure.
• Use or participation in other investigational device or drug study in which patient has not reached a primary endpoint to treat cardiovascular conditions related to the outcomes of the current study.

Más betegség

• Subject requires another planned major cardiac procedure, including left-sided transcatheter intervention or surgery (e.g. severe aortic stenosis, severe mitral regurgitation), coronary artery bypass or PCI or pulmonary valve correction. Please note that if closure of an ASD, iatrogenic ASD or PFO is performed, TricValve implantation can be performed 30 days after the intervention. Additionally, TricValve implantation can be performed 30 days after any Electrophysiology procedure (pacemaker, ICD, etc.).
• Cardiac amyloidosis
• Pulmonary artery systolic pressure (PASP) >65 mmHg assessed with Echo Doppler and /or right heart catheterization.
• Patient with refractory heart failure requiring advanced intervention (i.e. left ventricular assist device, transplantation) (ACC/ AHA/ ESC/ EACTS Stage D heart failure)
• Any known life-threatening condition with an estimated life span of at least 12 months.
• Endocarditis or active/ongoing infection requiring antibiotics.
• Known bleeding or clotting disorders or patient refuses blood transfusion.
• Active gastrointestinal (GI) bleeding within 3 months of randomization.
• Presence of significant congenital heart disease including but not limited to hemodynamically significant atrial septal defect, RV dysplasia, and arrhythmogenic RV.
• Any other condition that would preclude ability to meet study requirements in the opinion of the investigator.
• Psychiatric/behavioral issues or other medical or social conditions that preclude valid consent and follow-up

Laborértékek

• LVEF ≤ 30% on echocardiography.
• Platelet count < 75,000/mm3
• Severe renal insufficiency with estimated glomerular filtration rate (eGFR) ≤ 25 mL/min/1.73 m2 or requiring chronic renal replacement therapy at the time of enrollment.

Egyéb

• Evidence of intracardiac, inferior vena cava (IVC), or femoral venous mass, thrombus or vegetation.
• Tricuspid stenosis. (Per TVARC, echo criteria: TVA at least 1.5 cm2 or TVAi at least 0.9 cm2/m2 [at least 0.75 if BMI >30 kg/m2], DVI <2.2, mean gradient <5mm Hg); reduction of total tricuspid regurgitation to optimal (≤ mild [1+]) or acceptable (≤ moderate [2+]).
• Severe right ventricular dysfunction.
• Hemodynamically significant pericardial effusion.
• Child-Pugh Severity Class C (10-15 points).
• Unable to walk at least 60 meters in a 6minute walk test.
• Pregnant or breastfeeding subjects and those who plan pregnancy during the clinical investigation follow-up period.

• Subject must be 18 years or older, at the time of signing the informed consent.
• Subjects has severe tricuspid regurgitation (TR), as determined by the qualifying transthoracic echocardiogram (TTE) confirmed by an echocardiography Core Lab.
• NYHA Class III-IVa (not on inotropes, IABP or LVAD) or heart failure (HF) admission in the past 6 months.
• Subject is adequately treated with optimal medical therapy (OMT) for heart failure per the local Heart Team for at least 30 days prior to the index procedure, including a diuretic.
• The local Heart Team and IEC determine that the patient is eligible for the TricValve procedure.
• For females of childbearing potential, negative pregnancy test.
• Capable of giving signed informed consent.
