Lead Sponsor:

Medical University of Vienna

Conditions:

Mitral Regurgitation

ATTR-Cardiomyopathy

Eligibility:

All Genders

18+ years

Phase:

NA

Brief Summary

No previous study has evaluated the effectiveness of transcatheter edge-to-edge mitral valve repair (TEER) in patients with ATTR-associated cardiomyopathy (ATTR-CM) and significant mitral regurgitatio...

Detailed Description

It is the aim of this trial to investigate the effectiveness of TEER therapy in patients with proven ATTR-CM and concomitant significant MR as compared to medical therapy alone. Effectiveness will be ...

Eligibility Criteria

Inclusion

  • Inclusion criteria (all must be present)
  • Proven ATTR-CM
  • Significant symptomatic MR (3+ or 4+ by independent echocardiographic core laboratory assessment)
  • Subject has been adequately treated per applicable standards, including for coronary artery disease and heart failure (e.g., diuretics)
  • New York Heart Association (NYHA) functional class II, III, or ambulatory IV
  • Local heart team has determined that mitral valve surgery will not be offered as a treatment option, even if the subject is randomized to the control group
  • Left ventricular ejection fraction ≥20%
  • Anatomical feasibility for TEER as per discretion of the implanting investigator
  • Age 18 years or older
  • Subject or guardian agrees to all provisions of the protocol, including the possibility of randomization to the Control group and returning for all required post-procedure follow-up visits, and has provided written informed consent
  • Exclusion criteria (all must be absent)
  • AL-associated cardiomyopathy
  • Aortic or tricuspid valve disease requiring surgery or transcatheter intervention
  • Severe right ventricular dysfunction
  • Hemodynamic instability requiring inotropic support or mechanical heart assistance
  • Leaflet anatomy which may preclude TEER, proper device positioning on the leaflets or sufficient reduction in mitral regurgitation by TEER
  • Life expectancy \<12 months due to non-cardiac conditions
  • Prior mitral valve leaflet surgery or any currently implanted prosthetic mitral valve, or any prior transcatheter mitral valve procedure
  • Echocardiographic evidence of intracardiac mass, thrombus or vegetation
  • Active endocarditis or active rheumatic heart disease or leaflets degenerated from rheumatic disease (i.e., noncompliant, perforated)
  • Active infections requiring current antibiotic therapy
  • Transesophageal echocardiography (TEE) is contraindicated or high risk
  • Pregnant or planning pregnancy within next 12 months
  • Currently participating in another investigational device study that has not reached its primary endpoint
