Achieving Optimal Medical Therapy Through Percutaneous Treatment of Secondary Mitral Regurgitation to Improve Outcome in Patients With HFrEF

Korábbi kezelés

• Concurrent medical condition with a life expectancy of less than 12 months in the judgment of the investigator.
• Currently participating in another investigational therapeutic or interventional clinical trial, or in any trial of an unapproved drug, device or procedure. Note: Subjects participating in observational studies or registries may be considered as eligible.

Más betegség

• Terminal heart failure or hemodynamic instability
• Primary TR or MR, any other severe valvular heart disease
• Untreated clinically significant CAD (coronary artery disease) requiring revascularization
• Renal failure requiring dialysis
• Life expectancy <12 months due to non-cardiac conditions
• Active endocarditis or active rheumatic heart disease or leaflets degenerated from rheumatic disease (i.e., noncompliant, perforated)
• Active infections requiring current antibiotic therapy.
• Known hypersensitivity or contraindication to procedural device which cannot be adequately managed medically.

• Suboptimal GDMT therapy corresponding to a GDMT score <7 points
• Risk factor for not intensification of guideline directed medical therapy (at least one of the following):

  • Serum Potassium ≥ 4.8 mmol/L
• Persisting symptoms equalling NYHA functional class II-IVa (ambulatory)
• Patient has had at least one HF hospitalization within 12 months and/or a NT-proBNP ≥1000 pg/ml
