Three dimensional transesophageal echocardiography: a missing link in infective endocarditis imaging?

Area of Science:

• Cardiology
• Medical Imaging

Background:

• Two-dimensional echocardiography (2D ECHO) is the primary imaging modality for infective endocarditis (IE).
• Limitations exist in 2D imaging for complex IE cases.
• Three-dimensional (3D) echocardiography shows promise for enhanced IE assessment.

Purpose of the Study:

• To systematically review the role and incremental value of 3D transesophageal echocardiography (3D TE ECHO) in diagnosing and managing IE.
• To highlight the advantages of 3D TE ECHO over traditional 2D imaging for IE.

Main Methods:

• Review of existing literature on 3D TE ECHO in infective endocarditis.
• Comparison of 3D TE ECHO with 2D transthoracic (TT) and transesophageal (TE) ECHO.
• Analysis of 3D TE ECHO's impact on surgical planning and intervention.

Main Results:

• 3D TE ECHO provides superior, real-time anatomical visualization compared to 2D ECHO.
• 3D TE ECHO overcomes some limitations of 2D imaging in IE.
• 3D TE ECHO enhances surgical planning and facilitates surgeon-imager communication.

Conclusions:

• 3D TE ECHO is a valuable adjunctive tool for IE, particularly for surgical planning in specialized centers.
• While not the initial diagnostic choice, 3D TE ECHO offers significant incremental value.
• Future research should focus on integrating 3D TE ECHO with other imaging modalities like CT and MRI.
