Inclusion Criteria:
Exclusion Criteria:
Subjects act as own control
Device: Aortic Valve Replacement with EDWARDS INTUITY Valve System
Aortic Valve bioprosthesis
Percent of Early Adverse Events
Number of early adverse events occurring within 30 days of procedure divided by the total number of enrolled subjects times 100.
Time frame: Events occuring within 30 days of procedure
Percent of Late Adverse Events
Number of late adverse events divided by the total number of late patient years times 100. Late patient years are calculated from 31 days post-implant to the date of the last contact (follow up or adverse event).
Time frame: Events occurring >= 31 days and up through 5 years post-implant
Number of Subject's With Device Technical Success
Device technical success is defined as the successful delivery and deployment of one bioprosthesis with one delivery system with a maximum of two attempts.
Time frame: At time of surgery, an average of 3 hours
Number of Subject's With Procedural Success
Procedure success is defined as device technical success followed by the absence of adverse events requiring device reoperation, requiring implantation of permanent pacemaker, or subject death.
Time frame: Discharge(an average of 13 days) or 10 days post-implant, whichever comes first
Subject's New York Heart Association (NYHA) Functional Class Compared to Baseline
The New York Heart Association (NYHA) functional classification system relates symptoms to everyday activities and the patient's quality of life. Class I. No limitation of physical activity. Ordinary physical activity does not cause undue fatigue, palpitation, dyspnea (shortness of breath). Class II. Slight limitation of physical activity. Comfortable at rest. Ordinary physical activity results in fatigue, palpitation, dyspnea (shortness of breath). Class III. Marked limitation of physical activity. Comfortable at rest. Less than ordinary activity causes fatigue, palpitation, or dyspnea. Class IV. Unable to carry on any physical activity without discomfort. Symptoms of heart failure at rest. If any physical activity is undertaken, discomfort increases.
Time frame: 1 Month, 3 Months, 1 Year, 2 Years, 3 Years, 4 Years, and 5 Years post-implant
Subject's Average Score on the EQ-5D- Quality of Life Questionnaire Over Time
The EQ-5D is a standardized questionnaire that asks subjects to rate themselves (no problems, some problems, extreme problems) on mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. The scale is indexed and ranges from a minimum of 0.275 and a maximum of 1.000. A lower number indicates the participants experiences more problems and a higher number indicates the participants experiences fewer problems.
Time frame: Baseline, 3 Months, and 1 Year post-implant
Subject's Average Mean Systolic Gradient Measurements Over Time.
Mean gradient is the average flow of blood through the aortic valve measured in millimeters of mercury. Gradients are evaluated by echocardiography over time. Mean gradient values depend on the size and type of valve.
Time frame: Discharge (an average of 13 days), 1 Month, 3 Months, 1 Year, 2 Years, 3 Years, 4 Years, and 5 Years post-implant
Subject's Average Effective Orifice Area Measurements Over Time.
Effective orifice area represents the cross-sectional area of the blood flow downstream of the aortic valve. Effective orifice area is evaluated by echocardiography over time.
Time frame: Discharge (an average of 13 days), 1 Month, 3 Months, 1 Year, 2 Years, 3 Years, 4 Years, and 5 Years post-implant
Subject's Amount of Aortic Valvular Regurgitation Over Time
Aortic valvular regurgitation occurs when the aortic valve in the heart does not close tightly allowing some of the blood that was pumped out of the heart to leak back into it. Aortic valvular regurgitation is evaluated by echocardiography over time. It is assessed on a scale from 0 to 4, where 0 represents no regurgitation and 4 represents severe regurgitation.
Time frame: Discharge (an average of 13 days), 1 Month, 3 Months, 1 Year, 2 Years, 3 Years, 4 Years, and 5 Years post-implant
