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 prospective, single-arm, multi-center study. The objective of the study is to characterize the real-world performance of the Harmony TPV through 10 years post implant.
Study Population Patients with severe pulmonary regurgitation (i.e., severe pulmonary regurgitation as determined by echocardiography and/or pulmonary regurgitant fraction greater than or equal to 30% as determined by cardiac magnetic resonance imaging) who have a native or surgically-repaired right ventricular outflow tract and are clinically indicated for surgical pulmonary valve replacement.
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 N/A - Adverse Events: There has been no site reported adverse events, device deficiencies, surgical or catheter reinterventions reported for the study as of the data cutoff date.
