Progresses of echocardiography in evaluating coronary slow flow phenomenon / 中国医学影像技术

ABSTRACT

Coronary slow flow phenomenon (CSFP) is an angiographic diagnosis characterized by delayed peripheral coronary perfusion in the absence of significant epicardial coronary lesions.Cardiac structure and systolic function of most patients had no abnormality,but there might be recurrent chest pain with impairment in quality of life.Therefore,it is very important to diagnose and assess CSFP using noninvasive,easy and safe technique.With the development of echocardiography in recent years,CSPF can be quantitatively and qualitatively analyzed with conventional echocardiography,two-dimensional and three-dimensional speckle tracking echocardiography and myocardial contrast echocardiography.Progresses of echocardiography in evaluating CSFP were reviewed in this article.
