2003年11月17日 · A step-by-step approach to direct, transthoracic visualization of the LAD, Cx and RCA is presented. The technique of examination is discussed, correlations with basic coronary angiography views and heart anatomy are shown and extensively illustrated with photographs and movie-pictures.

Non-invasive imaging of coronary arteries by transthoracic echocardiography (TTE) is an emerging diagnostic tool for studying flow in the left main (LM), the left descending artery (LAD), the circumflex (Cx) and the right coronary arteries (RCA) [1,2].

2011年9月15日 · TTE is a good method for detection of distal flow in the LAD and PDA (usually distal RCA), and it has the main advantage among other noninvasive technologies being valid for easy, fast, direct assessment of distal CFVR.

2024年2月22日 · TTE findings of ALCAPA include an abnormal left coronary artery arising from the pulmonary artery with retrograde coronary flow (CFM adjusted to low scale frequency). Prominence of the RCA and coronary artery collaterals may also be present.

transthoracic echocardiographic (TTE) examination in 19805 and updated recommended components of the examination in 2011.6 Recently the British Society of Echocardiography updated a minimum dataset for standard adult transthoracic echocardiography,7 and the Swiss Society of Cardiology8 has established standards for the

We report a paediatric patient with an incidental finding of single RCA Lipton type RI pattern during assessment for transcatheter device closure of an ostium secundum atrial septal defect (secASD). Transthoracic echocardiography (TTE) revealed a dilated RCA, abnormal flow in the LAD, and no identifiable left main coronary artery.

2009年12月22日 · We aimed to assess the feasibility of TTE to visualise the complete segments of the left main (LM), left descending (LAD), circumflex (Cx) and right (RCA) coronary arteries. Methods: One hundred and eleven patients scheduled for diagnostic coronary angiography because of chest pain or acute coronary syndrome had a TTE study to map the passage ...

TTE is a sensitive and highly specific non-invasive method for diagnosis of LAD and RCA occlusions, based on the detection of the coronary blood flow direction in the epicardial and intramyocardial collaterals.

2003年11月17日 · Transthoracic measurements of coronary flow velocity were proved to be highly reproducible and correlated with invasive measurements. While clinical applications of transthoracic echocardiography (TTE) of principal coronary …

Transthoracic echocardiography (TTE) is the primary initial imaging modality in cardiac imaging. Advantages include portability, safety, availability, and ability to assess the morphology and physiology of the heart in a noninvasive manner.
