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 The primary objective of this PAS is to confirm the long-term safety and effectiveness of the Navitor Titan valve for patients at high or greater surgical risk, undergoing TAVR with the Navitor Titan Transcatheter Aortic Valve System in a contemporary real-world setting. The study is an observational real-world surveillance study
Study Population All patients that have undergone attempted TAVR with Navitor Titan valve at a TVT Registry participating site, from the date of PMA approval (January 13, 2023) through January 13, 2025, who are at “high or greater risk” of mortality with open surgery.
Sample Size There is no minimum sample size. The PAS will include all consecutive patients who have a Navitor Titan valve implant attempt at institutions participating in the STS/ACC TVT Registry within the first 2 years following PAS start date.
Key Study Endpoints This surveillance will monitor the following: (1) device success (intra-procedure); (2) all-cause mortality, all stroke, life-threatening/major bleeding, new requirement for dialysis, new pacemaker implant, peri-procedural myocardial
infarction, and repeat procedure for valve-related dysfunction (surgical or interventional therapy) at 30 days and 12 months; (3) neurological (non-stroke), vascular complications, and quality of life (KCCQ) outcomes at 30 days and 12 months; and (4) all-cause mortality, all stroke, and repeat procedure for valve-related dysfunction (surgical or interventional therapy) annually at 2-5 year post implantation.
Follow-up Visits and Length of Follow-up 5 years post-implant
