Subjects and methods: Sixty patients with ischemic heart disease who underwent coronary angiography and intravascular ultrasonography before and after percutaneous coronary intervention. Results: mean (±SD) stent length measured on IVUS was ± mm, which was longer than mean target lesion length ( ± mm), mean stent diameter was ± mm, equivalent to mean diameter of the far end reference lumen ( ± mm). The minimal lumen area (MLA) after the 2 intervention was ± compared with ± mm before intervention, minimum lumen diameter (MLD) after intervention was ± compared to ± mm before the intervention. The rate of completely lumen-attached stent was and of the cases had the stent that was opened following MUSIC standards. Conclusion: Intravascular ultrasonography (IVUS) is a technique that not only examines the nature of coronary injury accurately, but also evaluates the outcome of the intervention in a fairly comprehensive manner. * Keywords: Coronary artery; Percutaneous coronary artery; Intravascular ultrasound. INTRODUCTION Percutaneous coronary intervention is increasingly common in medical facilities. The main advantage of a percutaneous intervention is that it is easier to perform, avoid systemic anesthesia, open the chest, circulation outside the body, other complications and fast recovery. Thanks to this technique, coronary artery bypass grafts and circulatory reconstruction can also be performed quickly in emergencies. However, its disadvantage is early restenosis and that it does not fully cure chronic obstructive lesions and/or excess fibrosis. Intravascular .
