Intraoperative Echocardiography: Guide to Decision-Making

Area of Science:

• Cardiovascular Imaging
• Echocardiography
• Cardiac Surgery

Background:

• Transesophageal echocardiography (TEE) is crucial for intraoperative assessment.
• Valvular pathologies and mechanical circulatory support (MCS) present unique echocardiographic challenges.
• Current guidelines are essential for optimizing TEE use in complex cardiac cases.

Purpose of the Study:

• To review key recommendations for intraoperative echocardiography.
• To address challenges in assessing valvular disease and MCS.
• To provide insights for medical practitioners using TEE during surgery.

Main Methods:

• Review of updated guidelines from the American Society of Echocardiography (ASE) and ACC/AHA.
• Focus on the application of TEE in intraoperative settings.
• Analysis of TEE's role in valvular pathology and MCS assessment.

Main Results:

• Updated guidelines provide comprehensive recommendations for TEE use.
• TEE offers rapid evaluation of valvular/aortic pathology, hemodynamics, and cardiac function.
• Intraoperative TEE is vital for assessing and placing MCS devices, offering superior views compared to transthoracic echocardiography.
• TEE facilitates real-time surgical decision-making for valvular disease, including repair, replacement, or deferral.

Conclusions:

• Intraoperative TEE is indispensable for guiding surgical decisions in valvular disease and MCS.
• Adherence to updated guidelines improves TEE's diagnostic and monitoring capabilities.
• TEE empowers echocardiographers to provide critical real-time information for patient management.
