Enhanced Stent Imaging System Guided Percutaneous Coronary Intervention İs Linked to Optimize Stent Placement
Angiology(2022)
摘要
Purpose: Stent under-expansion utmost importance for restenosis, also one of the strongest predictors of Stent Thrombosis is stent under-expansion. Thus, it remains uncertain whether Enhanced stent imaging (CLEARstent) guidance improved stent under-expansion.Our aim to assess the using Enhanced stent imaging (ESI) on stent under-expansion, after percutaneous coronary intervention (PCI, with using CLEARstent technology.Methods: This cross-sectional observational based on single center study. The subjects who applied to our cardiology clinic with stable angina or acute coronary syndrome, from March 2020 to September 2020 were recruited. A total of 164 patients who underwent post-PCI clear stent in the study group and age sex matched 77 control patients were included in the study. Post-procedural minimal lumen diameter (MLD) was calculated with quantitative coronary angiography module.Results: Approximately one third of the study population was in X-ray guided PCI group and two third of which was involved in ESI guided PCI group (32% and 68%, respectively, p=0.22). The patients in ESI guided PCI group, median age was 61 (54-69) years and 76.8% (n=126) of whom were male.The patients in ESI guided PCI group have higher minimal lumen area when compared to X-ray guided PCI group (2.88 (2.58-2.99) vs 2.55 (2.34-2.63), p<0.001).Conclusion: Our study addresses that use of ESI system with intend to optimize stent placement results in better procedural outcome expressed by MLD.
