Transcatheter mitral valve repair in patient with atrial functional mitral regurgitation using novel DragonFly™ device

We report the first case of transcatheter mitral valve repair with the novel DragonFly™ device, a transcatheter edge-to-edge mitral regurgitation (MR) repair device, in a patient with severe, symptomatic MR due to annular dilation from atrial functional disease (Carpentier type I). The patient had experienced multiple heart failure events and was unsuitable for surgery due to pulmonary dysfunction and obesity.
