Primary Outcome Measures :
  1. All Cause Mortality [ Time Frame: 30 days ]
    Number of participants that reported all cause mortality

Secondary Outcome Measures :
  1. Number of Select Cardiovascular Adverse Events [ Time Frame: 30 days ]
    Number of participants with select cardiovascular adverse events

  2. Participant NYHA Classification at Day 30 [ Time Frame: day 30 ]

    The New York Heart Association (NYHA) functional classification system relates symptoms to everyday activities and the patient's quality of life.

    Class I. Patients with cardiac disease but without resulting limitation of physical activity.

    Class II. Patients with cardiac disease resulting in slight limitation of physical activity. They are comfortable at rest.

    Class III. Patients with cardiac disease resulting in marked limitation of physical activity. They are comfortable at rest.

    Class IV. Patients with cardiac disease resulting in inability to carry on any physical activity without discomfort. Symptoms of heart failure or the anginal syndrome may be present even at rest.

  3. Number of Participants With Acute Device Success [ Time Frame: 7 days ]
    1. Successful vascular access, delivery and deployment of the device and successful retrieval of the delivery system
    2. Correct position of the device in the proper anatomical location
    3. Intended performance of the prosthetic heart valve (Aortic Valve Area >1.2 cm2 and mean aortic valve gradient <20 mmHg or peak velocity <3 m/s, without moderate or severe prosthetic valve AR)
    4. Only one valve implanted in the proper anatomical location
