Orthotopic Transcatheter Tricuspid Valve Replacement

Abstract

Severe tricuspid regurgitation renders patients frail, and surgical treatment is associated with high mortality. Because most of the tricuspid regurgitation patients are functional and have significant annular dilation, large coaptation gaps are seen. This anatomy is best addressed with transcatheter tricuspid valve replacement (TTVR), and promising therapies are under clinical investigation. Most TTVR devices are in early clinical development with one transcatheter heart valve in pivotal trial; TTVR is expected to significantly affect tricuspid regurgitation and survival.
