TEE – Esophageal Ultrasound Probe for Real-Time Valve and Structural Heart Imaging

Описание: This video presents a technical overview of transesophageal echocardiography (TEE), focusing on the esophageal ultrasound probe used for real-time, high-resolution imaging of cardiac valves and structural heart anatomy. The system is examined from an engineering and imaging perspective, including the flexible insertion tube, tip articulation mechanisms, multiplane phased-array transducer, control handle, and the ultrasound console responsible for beamforming, signal processing, and image display. The video explains how the probe is positioned in the esophagus and stomach to obtain standard mid-esophageal, transgastric, and upper-esophageal views that place the transducer directly behind the heart.

Key topics include transducer frequency selection, 2D imaging, color Doppler, spectral Doppler, and 3D TEE capabilities, along with the role of TEE in assessing valve morphology and function, left atrial appendage thrombus, shunts, and peri-procedural changes during cardiac surgery and structural heart interventions. Probe motion controls, multiplane angle rotation, and safety-related design considerations are summarized at a conceptual level. The content is intended for students, clinicians, and biomedical engineers interested in echocardiography, ultrasound system design, and cardiac imaging, and is provided solely for educational and informational purposes without diagnostic or treatment recommendations.
