ABSTRACT
The SYNERGY coronary stent is new-generation drug-eluting stents, which has a thin-strut platinum-chromium platform with everolimus in a biodegradable polymer applied to the abluminal surface. It would be speculated that favorable arterial healing with early strut coverage could be achieved. The present study investigated the degree of strut coverage using optical coherence tomography (OCT) 2 weeks after SYNERGY implantation and clinical factors contributing to strut coverage. A total of 29 patients who underwent staged percutaneous coronary intervention (PCI) to residual lesions 2 weeks after the index PCI with SYNERGY stent implantation were enrolled. At the time of staged PCI, OCT examinations of the SYNERGY stent were performed for conventional OCT analysis on both cross-sectional and strut level. SYNERGY stent showed a high level of strut coverage and apposition, and the percentage was 82.4 ± 12.4% and 96.2 ± 5.0%, respectively. The lesion complexity was significantly related to greater strut coverage on univariate analysis; however, it was found to be insignificant in multivariate analysis. Our findings suggest early arterial healing after SYNERGY stent implantation.
