Imaging Needs in Novel Transcatheter Tricuspid Valve Interventions

Area of Science:

• Cardiology
• Medical Imaging
• Interventional Cardiology

Background:

• Severe tricuspid regurgitation (TR) management is evolving with new transcatheter therapies.
• Understanding TR pathophysiology is enhanced by advanced 3D imaging techniques.
• Accurate grading of TR and right ventricular assessment remain challenging.

Purpose of the Study:

• To review the role of multimodality imaging in patient selection for transcatheter tricuspid valve (TV) repair.
• To discuss the importance of pre-procedural imaging in planning transcatheter TR interventions.
• To highlight the increasing use of 3D echocardiography and cardiovascular magnetic resonance.

Main Methods:

• Review of current literature on imaging modalities for tricuspid regurgitation.
• Analysis of the application of 2D echocardiography, 3D echocardiography, and cardiovascular magnetic resonance.
• Focus on pre-procedural evaluation of TV anatomy, TR severity, and RV function.

Main Results:

• Novel 3D imaging provides better visualization of TV anatomy and TR pathophysiology.
• Multimodality imaging is essential for successful transcatheter TV repair procedural planning.
• The number of transcatheter interventions for TR is increasing.

Conclusions:

• Multimodality imaging plays a pivotal role in optimizing patient selection and procedural success for transcatheter TR therapies.
• Advanced imaging techniques improve the understanding and management of severe TR.
• Continued development and integration of imaging are key to advancing transcatheter TV repair.
