Transcatheter mitral valve repair in a high-surgical risk patient with severe degenerative mitral regurgitation using the novel DragonFly™ Transcatheter Repair device-First in man implantation in China.

Transcatheter repair of mitral regurgitation (MR) by edge-to-edge therapy has become increasingly accepted for patients with severe MR at high or prohibitive surgical risk in primary or degenerative mitral regurgitation (DMR). The technological approach has evolved from the initial transcatheter edge-to-edge device to improve on its acute reduction in MR and durability of results, particularly in complex primary pathology. In this study, we reported the first case of DragonFly™ Transcatheter Valve Repair device in a patient with severe DMR.
