Reduction of Mitral Regurgitation With the SATURN Trans-Septal Transcatheter Mitral Valve Replacement (TMVR) System in Patients With Severe Symptomatic Mitral Regurgitation

Korábbi kezelés

• Endocarditis in the 3 months prior to procedure date.
• COPD 2 on home oxygen therapy deemed too high risk for intubation.
• Myocardial infarction during prior 30 days.
• Stroke or TIA during prior 90 days.
• Severe extracardiac arteriopathy (safety measure for extra-circulatory support if surgical conversion is needed).
• Prior mitral valve treatment (e.g., valve repair or replacement, MitraClip, etc.), and/or anticipated mitral valve treatment prior to enrollment.
• Prior surgical mechanical valve AVR.
• Prior TAVI.
• CRT or ICD implanted in previous 30 days.
• CABG or PCI within previous 30 days.
• Prior or planned heart transplantation (UNOS status 1).

Más betegség

• Excessive frailty or comorbid conditions that preclude the anticipated benefit of the mitral valve replacement.
• Life expectancy <1 year due to noncardiac conditions.
• Current admission with acute heart failure exacerbation.
• Active systemic infection.
• Severe pulmonary arterial hypertension (PAH), defined as PASP > 60mmHg.
• Documented bleeding or coagulation disorders (hypo- or hyper-coagulable states).
• Severe connective tissue disease under chronic immunosuppressive or cortisone therapy.
• Need for any planned cardiovascular surgery or intervention (other than for MV disease) within 30 days post-index procedure.
• Inadequately treated for cardiac condition per applicable standards, such as for coronary artery disease, left ventricular dysfunction, mitral regurgitation, or heart failure, as reviewed by the Patient Screening Committee.
• Physical evidence of right-sided congestive heart failure:
  • Patients with ascites.
  • Patients with anasarca (generalized edema / hydropsy).
• Hypertrophic cardiomyopathy, restrictive cardiomyopathy, constrictive pericarditis, or other structural heart disease causing heart failure with the exception of dilated ischemic or non-ischemic cardiomyopathy.
  • Procedural Exclusion Criteria
• Known hypersensitivity or contraindication to procedural or post-procedural medication (e.g., contrast solution, anticoagulation therapy).
• Documented hypersensitivity to nickel or titanium.
• Contraindications to TEE imaging
  • Cardiac Imaging Exclusion Criteria

Laborértékek

• Chronic renal failure defined as eGFR <30 mL/min/m2 or on renal replacement therapy.
• Platelets < 90,000.

Egyéb

• General Exclusion Criteria

• Dependency on inotropic agents or mechanical circulatory support.
• Untreated clinically significant CAD.
• Modified Rankin Scale ≥4 disability.
• Refuses blood transfusions.
• Participating in other investigational studies likely to confound the results or affect the study.
• Unable or does not sign the study informed consent form.
• Patients classified as "vulnerable patients" 3 .
  • Cardiovascular Exclusion Criteria
• Cardiogenic shock, hemodynamic instability, Systolic Blood Pressure <90mmHg, Inotropic dependent or requiring IABP/mechanical circulatory support.
