Demonstration of Pathologic Coronary Flow Dynamics using Transthoracic Doppler Echocardiography: Its Potential Role in Clinical Decision-Making
نویسنده
چکیده
With advancements in high frequency transducers, transesophageal (TEE) and transthoracic Doppler echocardiography (TTE) are emerging as promising methods for the evaluation of coronary arteries. In addition to visualizing images for the detection of stenosis of the proximal and distal coronary arteries, as well as various kinds of coronary artery anomalies, the functional assessment through measurement of the coronary flow reserve using TEE and TTE have become valuable and additive tools for coronary angiography that define only the epicardial coronary arteries. Further efforts to develop new techniques, including real time 3D echocardiography, in the anatomic and functional assessments of coronary artery disease should be undertaken.

Coronary Flow Reserve Measurement by Transthoracic Doppler Echocardiography
Introduction Coronary flow reserve (CFR) is defined as a ratio of maximal (stimulated) to baseline (resting) coronary blood flow. CFR evaluation is important for the understanding of the pathophysiology of coronary circulation. CFR measurement is used both to assess epicardial coronary stenoses and to examine the integrity of microvascular circulation. An appreciation of coronary physiology is ...
متن کاملNoninvasive assessment of myocardial bridging in the left coronary artery by transthoracic Doppler echocardiography.
Myocardial bridging is a common congenital coronary abnormality recognized primarily with systolic narrowing or 'milking effect' shown by coronary angiography. We report the case of a 58-year-old man with signs and symptoms of myocardial ischemia who underwent transthoracic echocardiography and coronary angiography. The present case suggests the clinical role of transthoracic echocardiography i...
متن کاملTransthoracic Echocardiography in the Assessment of Coronary Arteries
Quantitative coronary angiography remains the reference standard for assessing coronary anatomy, measuring anatomic severity of the stenotic lesion and assisting in the process of intracoronary interventions. Thus, treatment of coronary artery disease (CAD) is performed primarily on the basis of anatomic measurements of stenosis severity, although the disease severity correlates better with phy...
متن کاملCoronary flow: a new asset for the echo lab?
Non-invasive imaging of coronary blood flow by transthoracic Doppler echocardiography is an emerging diagnostic tool to study the left anterior descending (LAD) and posterior descending (PD) coronary arteries. With this new clinical application of echocardiography, we can directly measure changes in coronary flow velocity reserve (CFVR) at the very beginning of the ischaemic cascade, instead of...
متن کاملAngiographically borderline left main coronary artery lesions: correlation of transthoracic doppler echocardiography and intravascular ultrasound: a pilot study
BACKGROUND the clinical decision making could be difficult in patients with borderline lesions (visually assessed stenosis severity of 30 to 50%) of the left main coronary artery (LM). The aim of the study was to evaluate the relationship between transthoracic Doppler (TTDE) peak diastolic flow velocity (PDV) and intravascular ultrasound (IVUS) measurements in the assessment of angiographically...
