An intravascular ultrasound (IVUS) is a new cardiological diagnostic technique which provides detailed cross-sectional images of the vessel wall, allows to investigate lumen, as well as structure of the coronary artery. This imaging technique has the unique potential to provide an image of atherosclerotic plaque, characterizes its composition, and severity of stenosis. "Soft" plaque, dense fibrous "hard" plaque, calcification and thrombosis have all been identified using IVUS. Intravascular ultrasound imaging has become a method for supporting interventional decision making by selecting patients who are to undergo Percutaneous Transluminal Coronary Angioplasty, Stent placement, Directional Coronary Atherectomy or Laser Angioplasty. Quality of measurements should allow more widespread use to guide interventional techniques. A series of IVUS imagings could assess the influence of plaque composition on mechanism of immediate lumen enlargement after revascularization. With utilization of IVUS guidance and high pressure balloon inflation--stent implantation could now be performed "optimally" and safely without anticoagulation. This original diagnostic tool is becoming a clinically useful adjunct to angiography in the assessment coronary arteries of heart transplant recipient and patients with higher risk of restenosis.
血管内超声（IVUS）是一种新的心脏病诊断技术，它能提供血管壁的详细横截面图像，可用于研究管腔以及冠状动脉的结构。这种成像技术具有独特的潜力，能够提供动脉粥样硬化斑块的图像，确定其成分以及狭窄程度。通过血管内超声已识别出“软”斑块、致密纤维“硬”斑块、钙化和血栓。血管内超声成像已成为一种辅助介入决策的方法，用于选择将接受经皮腔内冠状动脉成形术、支架置入、定向冠状动脉斑块旋切术或激光血管成形术的患者。测量的质量应允许其更广泛地用于指导介入技术。一系列血管内超声成像可评估斑块成分对血运重建后即刻管腔扩大机制的影响。借助血管内超声引导和高压球囊扩张，现在可以在不进行抗凝的情况下“优化”且安全地进行支架植入。这种原始的诊断工具正在成为评估心脏移植受者和再狭窄风险较高患者冠状动脉时血管造影的一种临床有用辅助手段。
