Abstract:
The contrast echocardiography used to be applied for the diagnosis of congenital heart diseases, analysis of right side heart hemodynamics, and the evaluation of peripheral blood flow profiles. Recently, myocardial contrast echocardiography is evoked for estimating regional coronary blood flow as a parallel procedure of interventional therapy for ischemic patients. Advanced technology such as harmonic imaging, rf signal processing and digital storage of the data are extremely supportive for the quantitative evaluation of myocardial blood flow. In addition, new contrast agents which enable interpretation of myocardial contrast could be administered by peripheral injection.
