Transesophageal echocardiography during surgery of the thoracic aorta in adults

Abstract

Thoracic aortic surgery poses significant challenges due to the complex anatomy and potential for life-threatening complications. Transesophageal echocardiography (TEE) has emerged as a crucial imaging tool in the management of patients undergoing these operations. TEE offers real-time, high-resolution imaging of the heart and aorta, enabling accurate assessment of aortic pathology, evaluation of cardiac function, and monitoring of intraoperative hemodynamics. Its semi-invasive nature, immediate availability, and ability to provide dynamic information make TEE an indispensable adjunct during these intricate procedures. One of the primary indications for TEE during thoracic aortic surgery is the assessment of aortic pathology, including aneurysms, dissections, and aortic valve diseases. TEE allows precise visualization of the extent, location, and severity of aortic lesions, facilitating decision-making regarding repair strategies, graft sizing, and intraoperative guidance. Furthermore, TEE aids in identifying associated cardiac abnormalities such as valvular or ventricular dysfunction, which may impact surgical planning and outcomes. This review aims to summarize the current evidence supporting the use of TEE during thoracic aortic surgical interventions and highlight its invaluable contributions to perioperative patient care.
