Objectives: The aim of this study was to evaluate the incidence and predictors of postprocedural incomplete stent apposition (ISA) after angiographically successful drug‐eluting stent (DES) implantation. Background: The deployed stents are usually evaluated by angiography alone; however, there are possibilities of postprocedural ISA despite the angiographically successful implantation. Methods: A total of 339 lesions in which poststent intravascular ultrasound (IVUS) was performed after successful DES implantation was included. Paclitaxel‐eluting stents were implanted in 237 lesions and sirolimus‐eluting stents (SES) in 102 lesions. Clinical, angiographic and procedural characteristics and IVUS findings for all cases were analyzed. Results: The overall incidence of ISA was 13.9% (47/339). By multivariate analysis, male gender (OR: 2.36, 95% CI: 1.09–5.11), deployment of SES (OR: 2.90, 95% CI: 1.49–5.67), the presence of intracoronary thrombus (OR: 7.47, 95% CI: 1.67–33.47), and non‐ST elevation myocardial infarction (OR: 2.73, 95% CI: 1.09–6.83) were independent predictors for postprocedural ISA after angiographically successful DES implantation. Conclusions: The incidence of postprocedural ISA after angiographically successful implantation of DES was not infrequent. A DES deployment strategy incorporating IVUS guidance might be helpful to reduce the incidence of postprocedural ISA. © 2009 Wiley‐Liss, Inc.
