Primary Outcome Measures:
  • Primary safety outcome measure: Event-free survival [ Time Frame: 1 month postprocedure and 2 years postprocedure (extended follow-up) ] [ Designated as safety issue: Yes ]
    Event-free survival is defined as survival free from device-related death

  • Primary efficacy outcome measure: Aortic valvular regurgitation [ Time Frame: 6 months postprocedure and 2 years postprocedure (extended follow-up) ] [ Designated as safety issue: No ]
    Aortic valvular regurgitation assessed by transthoracic echocardiography and graded as None/Trace (0), Mild (1+), Moderate (2+), Moderate-to-Severe (3+), or Severe (4+)

Secondary Outcome Measures:
  • Implant procedure success [ Time Frame: discharge or 14 days postprocedure, whichever comes first and 2 years postprocedure (extended follow-up) ] [ Designated as safety issue: Yes ]
    Success is defined as the absence of specified adverse events

  • Actuarial freedom from clinical cardiovascular events [ Time Frame: 1 month postprocedure and 2 years postprocedure (extended follow-up) ] [ Designated as safety issue: Yes ]
    Freedom from specified device and cardiovascular events

  • Event-free survival [ Time Frame: 6 months postprocedure ] [ Designated as safety issue: Yes ]
    Event-free survival is defined as survival free from device-related death

  • Left ventricle dimensions, volume and mass [ Time Frame: 6 months postprocedure and 2 years postprocedure (extended follow-up) ] [ Designated as safety issue: No ]
    Measures assessed by transthoracic echocardiography

  • Peak and mean systolic gradient [ Time Frame: 6 months postprocedure and 2 years postprocedure (extended follow-up) ] [ Designated as safety issue: No ]
    Measures assessed by transthoracic echocardiography

  • New York Heart Association (NYHA) Functional Capacity Classification [ Time Frame: 6 months postprocedure and 2 years postprocedure (extended follow-up) ] [ Designated as safety issue: No ]
    Four classes describing the effect of cardiac disease on physical activity: Class I - disease does not limit activity; Class II - slight limitation; Class III - marked limitation; Class IV - inability to carry out any physical activity without discomfort

Detailed Description:

Aortic Regurgitation, (also known as Aortic Insufficiency; AI), is the failure of the aortic valve to close completely during diastole which causes blood to flow from the aorta back into the left ventricle. Aortic Regurgitation (AR) is a frequent cause of both disability and death due to congestive heart failure, primarily in individuals forty or older, but can also occur in younger populations.

Traditionally management of aortic regurgitation has been by aortic valve replacement, however, as has been observed in patients who have had mitral valve repair, the option of maintaining ones native aortic valve versus a replacement, either bioprosthetic or mechanical, can have added multiple benefits. The advantage of repair is the avoidance of prosthetic valve-related complications with bioprosthetic valves over 10-15 years or the need for anticoagulation with mechanical valves and the related problems of this therapy. Therefore, potentially aortic valve repair is a good option for patients with AR or AI.
