[Stress echocardiography in localization of coronary atherosclerosis and assessment of it severity].
193 patients with coronary heart disease were examined to study potentialities of noninvasive diagnosis of coronary artery lesions, their location and severity using transesophageal echocardiography in combination with transesophageal stimulation. This method of stress-test proved highly sensitive (89%) and specific (84%) in noninvasive diagnosis of both location of coronary atherosclerosis and its severity (stenosis, subtotal stenosis, occlusion) and extension.
