Intraoperative transesophageal echocardiography (TEE) has become an important monitoring device for patients undergoing cardiac or noncardiac surgery. Complications associated with TEE are unusual, but the potential for TEE probe compression of the posterior vascular structures has been reported in pediatric patients. We present here a case of occlusion of the right subclavian artery in an adul...

This work studies the effect that argon and nitrogen atmospheres have on structure, phase composition, cytocompatibility, functional properties of porous NiTi alloys obtained by self-propagating high-temperature synthesis. Porous in atmosphere (NiTi-(N)) are characterized brittle interstitial phases Ti4Ni2O(N) appearance a finely dispersed TiNi3 comparison with alloy an (NiTi-(Ar)). An increase...

BACKGROUND AND PURPOSE Findings on transesophageal echocardiography (TEE) after ischemic stroke predict recurrent embolic events and prompt therapy; however, the additive predictive power of TEE findings on long-term mortality is unknown. Our goal was to study the impact of TEE findings on all cause mortality in ischemic stroke patients referred for TEE. METHODS We reviewed 245 consecutive pa...

Objective: This study was designed to compare the efficacy of simulator-based VRSim TEE training system and web-based virtual TEE program in training anesthetic residents. Methods: 28 second-year anesthetic trainees with no record of TEE experience were randomly assigned to two groups: simulator group and e-learning group. The simulator group undertaken training via simulator-based VRSim TEE tr...

According to guidelines established by the American Society of Anesthesiologists and the Society of Cardiovascular Anesthesiologists, life-threatening hemodynamic disturbances are classified as a category I indication for the intraoperative use of transesophageal echocardiography (TEE). However, the usefulness of TEE during intraoperative cardiac arrest and its impact on patient management have...

Over the past few decades, transesophageal echocardiography (TEE) has evolved from one-dimensional imaging using a probe with a single-crystal, M-mode transducer to two-dimensional imagingwith phased-array transducers and now three-dimensional (3D) imaging with matrix array transducers. Current 3D imaging probes are vastly superior to the earlier technique of using multi-plane TEE imaging to re...

Introduced in 1977, transesophageal echocardiography (TEE) offered imaging through a new acoustic window sitting directly behind the heart, allowing improved evaluation of many cardiac conditions. Shortly thereafter, TEE was applied to the intraoperative environment, as investigators quickly recognized that continuous cardiac evaluation and monitoring during surgery, particularly cardiac operat...
