INTRAVASCULAR ULTRASOUND FOR DIAGNOSIS OF LEFT MAIN CORONARY-ARTERY STENOSIS

Coronary angiography has many limitations for the assessment of corona ry artery disease. Intracoronary ultrasound imaging may overcome some of the these limitations by providing direct visualization of the lumi nal area. This report describes a case where intracoronary ultrasound imaging was useful for correct assessment of left main coronary artery disease which enabled avoidance of coronary artery bypass grafting in this patient. Intravascular ultrasound may be a good complement to co ronary angiography in selected cases of left main coronary artery lesi on.
