| Abstract | ||
| Background: Stent enhancement refers to adjunctive imaging or procedural techniques employed to optimize coronary stent deployment during percutaneous coronary intervention (PCI). These methods, including post-dilation, aim to ensure adequate stent expansion and proper apposition to the vessel wall, thereby improving both immediate and long-term clinical outcomes in patients with coronary artery disease (CAD). Aim: This study aimed to evaluate and compare the efficacy of stent enhancement techniques versus intravascular ultrasound (IVUS) guidance in optimizing stent deployment during PCI. Patients and methods: A prospective observational study was conducted on 60 patients undergoing PCI at Al-Azhar University Hospitals between June 4 and December 4, 2024. Institutional ethics approval and clinical trial registration were obtained. All patients underwent comprehensive clinical assessment, laboratory investigations, electrocardiography, echocardiography, coronary angiography, PCI, and either IVUS or stent enhancement during stent deployment. Results: Baseline demographic characteristics and comorbidities, including diabetes mellitus, hypertension, dyslipidemia, prior PCI, and smoking status, were comparable between the IVUS and stent enhancement groups. No significant differences were observed in ECG findings, left ventricular ejection fraction (LVEF), or regional wall motion abnormalities. Mean plaque burden was 0.74 ± 0.09%, and the median minimum lumen area was 2.6 mm². While involvement of the LAD, LMCA, and RCA was similar in both groups, LCX lesions were significantly more common in the IVUS group. Stent expansion was significantly better in the IVUS group. However, no statistically significant differences were noted in post-dilation, chest pain, major adverse cardiac events (MACE), or coronary calcium scores. Conclusion: Stent enhancement techniques were found to be non-inferior to IVUS in achieving adequate stent deployment and minimizing immediate procedural complications. However, IVUS demonstrated significantly superior stent expansion compared to stent enhancement, although no difference was observed in short-term MACE outcomes | ||
