Transesophageal Echocardiography - American Heart Association
2023年8月18日 · Transesophageal echocardiography (TEE) is a test that produces pictures of your heart. TEE uses high-frequency sound waves (ultrasound) to make detailed pictures of your heart and the arteries that lead to and from it.
Transesophageal Echocardiogram - Johns Hopkins Medicine
A transesophageal echocardiogram is done by inserting a probe with a transducer down the esophagus. This provides a clearer image of the heart because the sound waves do not have to pass through skin, muscle, or bone tissue.
Transesophageal echocardiography in the evaluation of the left ...
2022年3月24日 · As compared with transthoracic echocardiography, TEE offers superior visualization of posterior cardiac structures because of close proximity of the esophagus to the posteromedial heart with lack of intervening lung and bone. This proximity permits use of high-frequency imaging transducers that afford superior spatial resolution .
Transesophageal Echocardiogram - StatPearls - NCBI Bookshelf
2023年8月28日 · Transesophageal echocardiography (TEE) uses ultrasound waves to examine the heart and great vessels. There are four basic TEE rescue views that are all easy to obtain and helpful in determining the potential cause of cardiac arrest.

2024年8月3日 · What’s a Transesophageal Echocardiogram? Why Are TEEs Used? Are There any Risks With This Test? What’s a Transesophageal Echocardiogram? A transesophageal echocardiogram (TEE) is a type of...
Transesophageal echocardiography: Indications, complications, …
2024年3月8日 · Both TTE and TEE have a variety of clinical indications and applications. In most patients, TEE provides superior image quality, particularly for posterior cardiac structures which are nearer to the esophagus and less well visualized on transthoracic echocardiography as they are more distant from the anterior TTE transducer.
Functional Evaluation of the Heart by Transesophageal …
2017年1月26日 · Left ventricular ejection fraction (LVEF) is the most commonly measured parameter of ventricular systolic function. Global estimation of LVEF is often determined in a qualitative fashion; however, utilizing TTE or TEE, 2D imaging allows quantitative measurement of LVEF by assessing changes in ventricular volume during the cardiac cycle.
The Fundamentals of Transesophageal Echocardiography
2021年2月11日 · First introduced in 1987, transesophageal echocardiography (TEE) has become an essential imaging tool for the diagnosis of many cardiac conditions. In addition, TEE is routinely used during many surgical and percutaneous cardiac procedures for immediate assessment of cardiac function and structures.
TEE Transgastric Views - Echocardiographer.or
The transgastric views are among the most important transesophageal views and are the best TEE views for evaluating left and right ventricular function. As such, transgastric views are commonly employed in operative TEE to assess ejection fraction and …
A method for calculating left ventricular ejection fraction ...
2023年6月12日 · Measurement of ejection fraction (EF) by transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) is a standard method for evaluating cardiac function.
