The FDA has the authority to require sponsors to perform a post-approval study (or studies) at the time of approval of a premarket approval (PMA), humanitarian device exemption (HDE), or product development protocol (PDP) application. Post-approval studies can provide patients, health care professionals, the device industry, the FDA and other stakeholders information on the continued safety and effectiveness (or continued probable benefit, in the case of an HDE) of approved medical devices. This database allows you to search Post-Approval Study information by applicant or device information.

Detailed Study Protocol Parameters
Study Objectives 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 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).
Key Study Endpoints 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
Follow-up Visits and Length of Follow-up Annually through 5 years
