    1. Different Vascular Healing Patterns With Various Drug-Eluting Stents in Primary Percutaneous Coronary Intervention for ST-Segment Elevation Myocardial Infarction: Optical Coherence Tomographic Findings

      The introduction of optical coherence tomography has provided a new method for evaluating the vascular response to drug-eluting stents (DESs). We used optical coherence tomography to compare neointimal coverage and stent malapposition among DESs in patients with ST-segment elevation myocardial infarction. Optical coherence tomography was performed at 9 months after implantation of 3 types of DESs at the culprit lesions in 46 patients with ST-segment elevation myocardial infarction (16 sirolimus-eluting stents [SESs, Cypher Select], 11 paclitaxel-eluting stents [PESs, Taxus Liberte], and 19 zotarolimus-eluting stents [ZESs, Endeavor Sprint]). The neointimal thickness and apposition at each strut at each 1-mm interval and ...

      Comparison of Neointimal Coverage of Sirolimus-Eluting Stents and Paclitaxel-Eluting Stents Using Optical Coherence Tomography at 9 Months After Implantation

      The differences between using Sirolimus-eluting stents (SESs) and Paclitaxel-eluting stents (PESs) in the vascular response at 9 months after implantation were examined with optical coherence tomography (OCT). Methods and Results: OCT was carried out in 33 SESs [33 patients, 19 with acute coronary syndrome (ACS) and 14 with stable angina pectoris (SAP)] and 27 PESs (27 patients, 15 with ACS and 12 with SAP) at 9 months after stent implantation. Stent strut coverage and apposition at each strut were evaluated. The frequency of uncovered struts was significantly higher in SES (12.5±15.2 vs 4.9±7.9 %, P ...

    3. Evaluation in 3 Months Duration of Neointimal Coverage After Zotarolimus-Eluting Stent Implantation by Optical Coherence Tomography: The Endeavor OCT Trial

      ObjectivesWe performed this study to investigate the vascular response in early period after zotarolimus-eluting stent (ZES) (Endeavor Sprint, Medtronic CardioVascular, Minneapolis, Minnesota) implantation.BackgroundThe ZES has different characteristics, with biocompatible polymer and rapid drug-elution, compared with the first-generation drug-eluting stents (DES).MethodsThe ENDEAVOR OCT (Evaluation in 3 Months Duration of Neointimal Coverage after Zotarolimus-Eluting Stent Implantation by Optical Coherence Tomography) trial is a prospective, single-center study evaluating vascular healing patterns with optical coherence tomography (OCT) at 3 months after stent implantation. A total of 31 ZES in 30 patients underwent serial OCT at immediate post-intervention and 3 months. Neointimal growth ...

    4. The Prevalence and Determinant Factors of Intracoronary Thrombus Formation After Various Types of Drug-Eluting Stents Implantation: Optical Coherence Tomography Study

      Backgrounds: Intracoronary thrombus has been commonly shown after sirolimus eluting stent (SES) implantation in optical coherence tomography (OCT) examination. But, there was no data for other drug eluting stents (DES). Therefore, we investigated the prevalence and relating factors of intracoronary thrombus after various DES implantations using OCT. Methods: Two hundred twenty six patients [244 stents: 95 SES, 62 paclitaxel eluting (PES) and 87 zotarolimus eluting stent (ZES)] underwent OCT examination at mean 11 months (3– 66 months) after stent implantation. OCT evaluation focused on the thrombus, neointimal coverage and malapposition at each strut. The baseline, angiographic and OCT findings were ...

    5. Different patterns of neointimal coverage between acute coronary syndrome and stable angina after various types of drug-eluting stents implantation; 9-month follow-up optical coherence tomography study

      BackgroundAcute coronary syndrome (ACS) is an independent risk factor for late stent thrombosis which might be related to the impaired vascular healing after drug-eluting stent (DES) due to the disruption of plaques and thrombus formation. Therefore, we investigated the vascular response after various DES implantations between ACS and stable angina pectoris (SAP) using optical coherence tomography (OCT).MethodsNinety-one patients [49 ACS: 20 sirolimus-eluting (SES), 12 paclitaxel-eluting (PES) and 17 zotarolimus eluting stent (ZES) and 42 SAP: 15 SES, 12 PES and 15 ZES] underwent OCT at 9months after stent implantation. Neointimal coverage and malapposition were evaluated in 21,939 struts ...
