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.
