Detailed Study Protocol Parameters |
Study Design Description |
A longitudinal observational clinical trial following subjects that were enrolled in the Medtronic CoreValve® Continued Access Study (CAS) and received the Medtronic CoreValve® System (MCS).
Not a hypothesis driven study.
|
Study Population Description |
Extreme risk subjects currently consented to and enrolled in the Medtronic U.S. CAS Protocol, and implanted with the MCS.
|
Sample Size |
All subjects enrolled in the CoreValve® Continued Access Study (approximately 2250, including both ilio-femoral and non-ilio-femoral implant access) at all sites (up to 45).
|
Data Collection |
Primary endpoints: all-cause death or major stroke at 6 months and annually through 5 years.
Secondary endpoints: The following endpoints will be assessed at 1 month, 6 months, and annually through 5 years:
1. Major Adverse Cardiovascular and Cerebrovascular Event (MACCE) event rates via Kaplan-Meier. MACCE is defined as a composite of:
¿ all-cause death
¿ myocardial infarction (MI)
¿ all stroke, and
¿ reintervention (defined as any cardiac surgery or percutaneous reintervention catheter procedure that repairs, otherwise alters or adjusts, or replaces a previously implanted valve)
2. The occurrence of individual MACCE components event rates via Kaplan-Meier
3. Major Adverse Events (MAE) event rates via Kaplan-Meier
4. Conduction disturbance requiring permanent pacemaker implantation event rates via Kaplan-Meier
5. Change in NYHA class
6. Quality of Life (QoL) change using the following measures:
¿ Kansas City Cardiomyopathy Questionnaire (KCCQ)
¿ SF 12, and
¿ EuroQoL7. Echocardiographic assessment of valve performance using the following measures:
¿ transvalvular mean gradient
¿ effective orifice area
¿ degree of aortic valve regurgitation (transvalvular and paravalvular)
8. Aortic valve disease hospitalization event rates via Kaplan-Meier
9. Cardiovascular deaths and valve-related deaths event rates viaKaplan-Meier
10. Strokes (of any severity) and TIAs event rates via Kaplan-Meier
11. Evidence of prosthetic valve dysfunction
