Abstract

Background: In-stent thrombosis and re-stenosis are common in PCI patients, and are significantly influenced by the coronary stent under expansion. These complications can be detected by IVUS which is not used routinely in daily practice, being expensive, time- consuming, and requires trained operators and laboratory staff. Aim of the Work: compared intravascular ultrasound with stent boost imaging for the evaluation of the best stent deployment. Patients and Methods: this study comprised 30 patients who underwent elective PCI with IVUS and stent boost and had chronic coronary artery disease with anatomical or functional evidence of ischemic coronary artery disease. Results: were: SB demonstrated favorable agreement to IVUS for MSD, which improved to ideal agreement when performed at a cutoff value of 76% for MSD/distal RLD, SB was capable of detecting ideal expansion in comparison to IVUS, having 100% sensitivity and 66.67% specificity (p = 0.005, AUC = 0.808). Conclusion: stent boost demonstrated favorable agreement to IVUS for MSD, which improved to ideal agreement when performed.
