Emerging Concepts in Transesophageal Echocardiography

Area of Science:

• Cardiology
• Medical Imaging
• Echocardiography

Background:

• Transesophageal echocardiography (TEE), introduced in 1977, revolutionized cardiac imaging by utilizing a unique acoustic window behind the heart.
• Early adoption of TEE in the intraoperative setting enabled continuous cardiac evaluation and monitoring during surgical procedures, especially cardiac operations.

Purpose of the Study:

• This review focuses on four recent advancements in perioperative TEE.
• The review aims to discuss the clinical applications and impact of these new TEE techniques.

Main Methods:

• The review synthesizes recent literature on four key areas of TEE advancement.
• Focus areas include three-dimensional (3D) TEE imaging, continuous TEE monitoring in the intensive care unit (ICU), strain imaging, and assessment of diastolic ventricular function.

Main Results:

• Three-dimensional TEE offers enhanced visualization of cardiac structures.
• Continuous TEE monitoring in the ICU provides real-time hemodynamic assessment.
• Strain imaging allows for detailed myocardial function analysis.
• Advanced diastolic function assessment improves the understanding of ventricular filling dynamics.

Conclusions:

• Recent TEE innovations significantly enhance perioperative cardiac assessment.
• These advancements contribute to improved patient management and outcomes in cardiac surgery and critical care settings.
