title: [Intracoronary ultrasound].
abstract: IVUS imaging provides a 2-dimensional, cross-sectional view into the lumen and vessel wall structure of coronary arteries; it is superior to angiography with regard to visualization about several aspects of coronary artery disease. IVUS has given important information on the development and progression of coronary atherosclerosis. Moreover, IVUS has improved our understanding of the mechanisms of percutaneous interventions and restenosis. IVUS-guided balloon sizing during PTCA may increase acute lumen gain as compared to conventional angiographic guidance. Optimization of stent implantation by IVUS guidance also results in larger initial lumen gain than with angiographic control; this approach, however, does not reduce restenosis rates. In summary, IVUS is an optional imaging modality that provides clinically useful information in selected patients.
