Abstract
Echocardiography is essential in evaluating patients presenting various manifestations of coronary artery disease. No other imaging modality can readily provide such a wealth of information noninvasively and relatively inexpensively at the patient′s bedside. The role of echocardiography in coronary artery disease has evolved with changes in the management strategy of coronary artery disease. Transthoracic Doppler echocardiography enables us to diagnose coronary artery stenosis or occlusion based on coronary artery flow or coronary flow reserve (CFR). Stress echocardiography is useful for diagnosing myocardial ischemia and viability. Transthoracic echocardiography provides functional and hemodynamic information, as well as anatomic information, in the clinical setting.
