Assessment and procedural guidance with echocardiography for transcatheter tricuspid regurgitation devices.

Echocardiographic imaging is an integral part of characterizing patients with tricuspid regurgitation (TR) and helps in determining the timing of intervention and procedural guidance for transcatheter interventions. The rapid advances in both two-dimensional and three-dimensional imaging however have facilitated the development and deployment of novel transcatheter devices to address the unmet need for patients with symptomatic severe TR.
