Key result
3D MPR ICE demonstrates utility for guiding T-TEER using the PASCAL device.
Why the study?
Procedural success of tricuspid TEER depends on high-quality imaging, and while transesophageal echocardiography remains the standard, 3D MPR ICE offers theoretical and practical advantages.
3D MPR ICE offers theoretical and practical advantages for guiding tricuspid TEER procedures compared to standard transesophageal echocardiography.
May offer TEE alternative for tricuspid TEER guidance; leaves open need for comparative validation before wider adoption.
Patients with severe symptomatic tricuspid regurgitation face a significant dilemma in treatment options, as the yearly mortality with medical therapy and the surgical mortality for tricuspid repair or replacement are high. Transcatheter edge-to-edge repair (TEER) for the tricuspid valve is becoming a viable option in patients, although procedural success is dependent on high-quality imaging. While transesophageal echocardiography remains the standard for tricuspid TEER procedures, intracardiac echocardiography (ICE) with three-dimensional (3D) multiplanar reconstruction (MPR) has many theoretical and practical advantages. The aim of this article was to describe the in vitro wet lab-based imaging work done to facilitate the best approach to 3D MPR ICE imaging and the procedural experience gained with 3D MPR ICE in tricuspid TEER procedures with the PASCAL device.

Chadderdon et al. (2022) conducted a review in Severe symptomatic tricuspid regurgitation. Three-dimensional multiplanar reconstruction intracardiac echocardiography (3D MPR ICE) vs. Transesophageal echocardiography was evaluated. Three-dimensional multiplanar reconstruction intracardiac echocardiography was described for guiding tricuspid transcatheter edge-to-edge repair using the PASCAL device.
