Post-Approval Studies (PAS) Database

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.

Sample Size	150
Key Study Endpoints	Proportion of patients without valve intervention and with acceptable hemodynamic function at 6 months, procedure success at 30 days, as well as freedom from all-cause mortality, freedom from reoperation, freedom from catheter reintervention, freedom from TPV dysfunction, and serious procedure- and device-related adverse events at 6 months and annually through 10 years.
Follow-up Visits and Length of Follow-up	10 years
Interim or Final Data Summary
Interim Results	Safety Results Number of Subjects with CEC Adjudicated Adverse Events (Serious Device- or Serious Procedure-Related AEs): CVA: 0.7% (1); Congestive heart failure: 1.3% (2); Erosion: 0.7% (1); Heart block, 3rd degree: 0.7% (1); Hemorrhage: major, life threatening: 1.3% (2); Thrombosis of the TPV: 0.7% (1); Ventricular premature beats 0.7% (1); Ventricular tachycardia, sustained: 1.3% (2) Effectiveness Results There have been 2 surgical reoperations and 3 catheter reinterventions reported. There has been 1 event of major stent fracture and 16 minor stent fractures have been reported by the Radiography core laboratory.
