Multimodality imaging in tricuspid regurgitation: A primer

Area of Science:

• Cardiology
• Medical Imaging

Background:

• Tricuspid regurgitation (TR) is a common cardiac condition with significant prognostic implications.
• Limited surgical options for TR have spurred interest in interventional therapies.
• Recent trials highlight the safety and quality-of-life benefits of interventional TR management.

Purpose of the Study:

• To review the role of advanced imaging modalities in the interventional management of tricuspid regurgitation.
• To discuss the advantages and limitations of echocardiography, cardiac MRI, and cardiac CT for TR assessment.
• To cover preoperative, intraprocedural, and postprocedural imaging considerations for tricuspid transcatheter interventions.

Main Methods:

• Review of current literature on imaging techniques for tricuspid regurgitation.
• Analysis of echocardiography, cardiac magnetic resonance (CMR), and cardiac computed tomography (CCT) for TR evaluation.
• Discussion of key imaging parameters for preoperative assessment and procedural guidance.

Main Results:

• Echocardiography, CMR, and CCT offer distinct advantages and face specific challenges in TR assessment.
• Accurate characterization of TR etiology, severity, and right heart anatomy is vital for interventional success.
• Imaging plays a critical role throughout the interventional tricuspid procedure lifecycle.

Conclusions:

• Advanced imaging is indispensable for the successful interventional treatment of tricuspid regurgitation.
• A comprehensive understanding of imaging modalities optimizes patient selection and procedural outcomes.
• Future advancements in imaging will further enhance interventional TR therapies.
