Previous clinical registries run by professional societies have been developed to monitor results of established procedures. The transcatheter valve therapy (TVT) registry will prospectively capture patients immediately after device approval. There are plans to potentially expand the TVT registry into the pre-PMA period to further bring data element standardization and efficient transitions from the pre-approval to post-approval phases of device evaluation. PMA = premarket approval; RCT = randomized clinical trial. Figure Legend:

The process of enrollment can take some time for hospitals to complete, and the few remaining sites are expected to complete the process soon.

Acceleration of entries occurred after the national coverage decision from the Center for Medicare and Medicaid Services announced the reimbursement requirements that included registry participation. Sites are still entering their backlog of completed cases. As of August 7, 2013 there were 8,108 patient records entered. Abbreviations as in Figure 2. Figure Legend:
