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.

Freedom from serious adverse events
Freedom from device events (embolization, device removal, or other device intervention)
• Clinically Significant New Arrhythmia
Follow-up Visits and Length of Follow-up Total of 3 years post-procedure.
Interim or Final Data Summary
Interim Safety Information Both primary and secondary endpoints have been met in comparison to performance goals
derived from clinical study outcomes for devices indicated fro ASD clsure.
Actual Number of Patients Enrolled 613
Actual Number of Sites Enrolled 22
Patient Follow-up Rate 30 day visit: 97.3%; Month 6 Visit: 95.1%; Month 12 Visit: 90.1%; Month 24 Visit: 85.8%; Month
36 Visit: 75.4%
Final Safety Findings ¿ Of the 613 evaluable subjects, 25 subjects experienced one or more SAEs within 30 days post-index
¿ 49 subjects reported a total of 77 SAEs, 31 SAEs are device-related, 7 SAEs are procedure-related.
¿ 371 subjects (60.5%) reported at least one MedDRA-coded AE.
Final Effect Findings Of the 566 subjects with technical success, 516 completed 6-month clinical residual defect
check, 100% (516/516) achieved 6-month clinical closure success
¿ Of the 577 subjects who have completed 6-month composite clinical success evaluation, 503
(87.2%) achieved Composite Clinical Success, 74 (12.8%) experienced clinical Failure at 6-month
¿ Technical and procedure success rates were both 92.3%
Study Strengths & Weaknesses This study follows up the IDE and Continued Access cohorts through three years post-procedure
and provides longer term safety and effectiveness results of the GORE CARDIOFORM ASD
Occluder device.
