Strut Coverage and Vessel Wall Response to Zotarolimus-Eluting and Bare-Metal Stents Implanted in Patients With ST-Segment Elevation Myocardial Infarction: The Octami (Optical Coherence Tomography in Acute Myocardial Infarction) Study
Explore Article interventions.onlinejacc.org (Jun 21 2010)
Objectives Using optical coherence tomography, we assessed the proportion of uncovered struts at 6-month follow-up in zotarolimus-eluting stents (ZES), specifically Endeavor (Medtronic CardioVascular, Santa Rosa, California) stents, and identical bare-metal stents (BMS) implanted in patients with ST-segment elevation myocardial infarction (STEMI). Background Sirolimus- and paclitaxel-eluting stents implanted in STEMI have been associated with delayed healing and incomplete strut coverage. ZES are associated with a more complete and uniform strut coverage in stable patients, but whether this holds true also after STEMI is unknown. Methods Forty-four patients with STEMI who underwent primary PCI were randomized to ZES or BMS (3:1 randomization). ...

Reproducibility of quantitative optical coherence tomography for stent analysis
Explore Article eurointervention.org (Jul 5 2009)
Aims: To assess the inter- and intra- observer reproducibility for strut count, strut apposition and strut tissue coverage measurements with optical coherence tomography (OCT).Methods and results: Ten drug-eluting stents (244 frames, 1712 struts) imaged with OCT nine months after implantation were analysed by two independent analysts. One of the analysts repeated the analysis of five stents (120 frames, 795 struts) one week later. Offline analysis was performed with the proprietary LightLab Imaging software. The number of struts was counted and lumen and stent area contours were traced. Tissue coverage thickness was measured at 360 degrees of vessel circumference and in ... (Read Full Article)
