Key result
3D ICE effectively guides transcatheter tricuspid valve interventions as an adjunct or standalone modality.
Why the study?
The emergence of transcatheter tricuspid valve interventions has introduced new imaging needs, with 3D intracardiac echocardiography re-emerging as an adjunct or standalone modality for procedural guidance.
3D intracardiac echocardiography represents an emerging alternative or adjunct to transesophageal echocardiography for guiding complex transcatheter tricuspid valve interventions.
Interventions for tricuspid regurgitation (TR) have been historically confined to surgical procedures. The emergence of transcatheter tricuspid valve interventions (TTVI) provides alternative and additional treatment options for patients with severe symptomatic TR. Transesophageal imaging has been the quintessential imaging modality for intra-procedural guidance for tricuspid interventions. More recently, three-dimensional intracardiac echocardiography (3D ICE) imaging has re-emerged as an adjunct or standalone imaging modality for these interventions. This review article aims to address the use of 3D ICE imaging in tricuspid valve repair and replacement procedures, while outlining key differences in imaging strategies between the two procedures. The focus is not to define when 3D ICE should be used, but rather how to use it effectively when it is selected as the imaging modality.

Hamid et al. (2026) conducted a review in Severe symptomatic tricuspid regurgitation. Three-dimensional intracardiac echocardiography (3D ICE) was evaluated. Three-dimensional intracardiac echocardiography (3D ICE) serves as an effective adjunct or standalone imaging modality for guidance during transcatheter tricuspid valve interventions.
