K-clip™, a Novel Transcatheter Treatment in Patients with Severely Tricuspid Regurgitation.

Patients who suffer from severe tricuspid regurgitation (TR) and who are at high surgical risk have no standard care therapy. Therefore, minimally invasive and safer methods are sought. K-clip™, the first ultrasound-positioned interventional tricuspid annuloplasty instrument intended for percutaneous transcatheter repair. We report a patient with severe functional TR and high surgical risk who underwent K-clip™ tricuspid annuloplasty under echocardiography and fluoroscopy guidance.
