One-year outcomes of transcatheter tricuspid valve repair with the Mistral device

Transcatheter tricuspid valve intervention (TTVI) has become a valuable treatment option and may be considered in inoperable patients with severe symptomatic tricuspid regurgitation (TR) and a suitable anatomy in whom improvement can be expected1.
