Åtgärdsbeskrivning
Tidsram
Antal tidiga biverkningar dividerat med antal försökspersoner (uttryckt i procent)
Tidsram: Händelser som inträffar inom 30 dagar efter proceduren
Antal tidiga biverkningar som inträffar inom 30 dagar efter proceduren dividerat med antalet inskrivna försökspersoner gånger 100
Händelser som inträffar inom 30 dagar efter proceduren
Number of Late Adverse Events Divided by Late Patient Years (Expressed as a Percentage)
Tidsram: Events occurring >= 31 days and up through 5 years post-implant
Number of late events divided by the total number of late patient years x 100. Late patient years are calculated from 31 days post-implant to the date of the last contact (follow up or adverse event).
Events occurring >= 31 days and up through 5 years post-implant

Tidsram
Subject's Average Mean Gradient Measurements
Tidsram: Baseline through 5-Year (at each scheduled follow-up visit)
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.
Baseline through 5-Year (at each scheduled follow-up visit)
Subject's Average Effective Orifice Area Measurements
Tidsram: Baseline through 5-Year (at each scheduled follow-up visit)
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.
Baseline through 5-Year (at each scheduled follow-up visit)
Subject's New York Heart Association (NYHA) Functional Class Compared to Baseline.
Tidsram: 3-6 Months and 1 through 5 Years 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. 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.

3-6 Months and 1 through 5 Years compared to baseline
Subject's Average Score at Baseline and 1 Year on the Quality of Life Survey
Tidsram: Baseline and one year follow-up

The Medical Outcomes Study Short-Form 12 (SF-12) contains two components - the Physical Component Summary (PCS) and the Mental Component Summary (MCS).

The SF-12 Physical Component Summary questionnaire scale ranges from a maximum of 100, which reflects the best health status to a minimum of 0, which reflects the worst health status.

The SF-12 Mental Component Summary scale ranges from a maximum of 100, which reflects the best health status to a minimum of 0, which reflects the worst health status.

Baseline and one year follow-up
Subject's Average Score on the EQ-5D- Quality of Life Questionnaire Over Time
Tidsram: Baseline and 1 Year
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.
