Transesophageal echocardiography (TEE) is a valuable diagnostic and intraoperative tool that allows high-resolution, real-time imaging of deep cardiovascular structures without interfering with surgery. It offers dynamic information similar to computed tomography (CT) or magnetic resonance imaging (MRI) but without radiation exposure, making repeated assessments feasible. During cardiovascular surgery, TEE guides cannula placement, monitors myocardial protection, detects complications like air embolism and intraoperative aortic dissection, and facilitates real-time surgical navigation. Its utility extends to postoperative intensive care unit (ICU) care and emergency settings, where it helps diagnose complications when CT is not feasible. In thoracic surgery, TEE aids in assessing tumor invasion into cardiovascular structures. However, TEE’s effectiveness heavily relies on the operator’s skill, unlike the objectivity of radiologic modalities. Thus, fostering collaboration between anesthesiologists and surgeons is essential. As a critical part of perioperative management, TEE proficiency is now a requirement for board certification in cardiovascular anesthesia in Japan. Supporting anesthesiologists in developing TEE skills enhances surgical outcomes and institutional capability.
