Intraoperative Transesophageal Echocardiography in Acute Type A Aortic Dissection: Contemporary Approach.

Area of Science:

• Cardiovascular Surgery
• Medical Imaging
• Anesthesiology

Background:

• Acute type A aortic dissection is a life-threatening surgical emergency with high mortality.
• Computed tomography angiography is standard for diagnosis, but intraoperative imaging is essential.
• Transesophageal echocardiography (TEE) is indispensable for real-time intraoperative assessment.

Purpose of the Study:

• To review intraoperative transesophageal echocardiography (TEE) findings in type A aortic dissection surgery.
• To highlight TEE's role in detecting complications and guiding surgical management.
• To emphasize TEE's utility in improving patient outcomes for aortic dissection.

Main Methods:

• Review of intraoperative transesophageal echocardiography (TEE) findings.
• Discussion of TEE's application in diagnosing and managing type A aortic dissection.
• Emphasis on real-time imaging for surgical decision-making.

Main Results:

• Intraoperative TEE confirms diagnoses, monitors hemodynamics, and evaluates the aortic valve and surrounding spaces.
• TEE differentiates true and false lumens and guides aortic cannulation.
• Post-bypass TEE assesses surgical results and guides further interventions.

Conclusions:

• Intraoperative TEE is vital for comprehensive surgical management of type A aortic dissection.
• Increased awareness and utilization of TEE can lead to improved patient outcomes.
• TEE provides critical real-time data for informed surgical decisions and interventions.
