Detailed Description

The ALIGN study is a single arm, prospective study. The objective of the study is to investigate the safety and performance of a catheter-based plication device intended to reduce the circumference of the dilated mitral valve. The study will enroll up to 50 subjects from up to 5 sites (Paraguay, Columbia, Dominican Republic, Brazil, and India) who will be followed for 36 months post index procedure. Enrollment is defined at the time the study device is inserted into the body and patients will be followed at 30 days, and Months 6, 12, 24 and 36 post index procedure.


  • Device: percutaneous annuloplasty
    • plication of the mitral valve annulus

Arms, Groups and Cohorts

  • Experimental: annuloplasty
    • All patients will receive treatment with the Mitralign Percutaneous Annuloplasty System (MPAS).

Clinical Trial Outcome Measures

Primary Measures

  • Major Adverse Events (MAE)
    • Time Frame: within 30 days post procedure
    • MAE defined as occurrence of any of the following: Mitral valve-related surgery/intervention, myocardial infarction, cardiac tamponade, stroke, device and/or procedure-related death

Secondary Measures

  • Echocardiographic Outcomes
    • Time Frame: at 6 months
    • Freedom from an increase in ventricular diameter
