## In plain language

A way to repair a leaking heart valve with a device delivered by a catheter, a thin tube passed through a blood vessel. The name is short for transcatheter edge-to-edge repair. It is used on the mitral valve and on the tricuspid valve, each with its own clip device. In trials it was added to medicines and compared with medicines alone.

## Technical summary

The TRILUMINATE abstract calls its procedure percutaneous tricuspid transcatheter edge-to-edge repair (TEER), and the US approval wording for the tricuspid device uses transcatheter edge-to-edge valve repair. The COAPT registry lists a paper titled with mitral transcatheter edge-to-edge repair among the publications of the trial, and the COAPT abstract itself calls the procedure transcatheter mitral-valve repair. A US government patient page lists a device implanted to treat mitral regurgitation among the repair options, noting it suits people for whom open-heart surgery is not advised. This record describes the approach by the names and indications in those sources and gives no account of how the device works, which none of them states.
