“…Neointimal thickness was calculated by subtracting the luminal cross-sectional areas from the stent. The strut appearance and coverage was qualified as embedded, protruding covered, protruding uncovered and malapposed according to previously described definitions [15,16].…”

Background: Novel sirolimus eluting stents (SES) have shown non-inferior clinical outcomes when compared to everolimus eluting stents (EES), EES and BMS (0.18 ± 0.1 vs. 0.39 ± 0.1 vs. 0.34 ± 0.2 mm, respectively; p = 0.04). There was no difference in the proportion of malapposed or uncovered struts, although protruding covered struts were more common in p = 0.03). (0.24 ± 0.1 vs. 0.4 ± 0.1 vs. 0.77 ± 0.4; p < 0.01) whilst EES and BP-SES had higher fibrin scores than BMS (1.2 ± 0.4 vs. 1.3 ± 0.3 vs. 0.17 ± 0.2; p < 0.01 (Cardiol J 2016; 23, 6: 657-666) In pathology, the lowest neointimal thickness was confirmed in BP-SES (p < 0.05). The inflammation score was significantly lower in BP-SES and EES when compared to BMS

“…The inclusion criterion for the study was angiographically documented restenosis (≥50% diameter stenosis) with a DES (SES and PES) or BMS that necessitated referral for target lesion revascularization (TLR) with monitoring by OCT. The exclusion criteria were: (a) left main coronary artery disease, (b) target artery not anatomically suitable for OCT, 23 such as an ostial, severely tortuous or heavily calcified lesion, (c) congestive heart failure, (d) renal insufficiency, (e) contraindication for antiplatelet therapy, and (f) a lesion in which a preprocedural OCT examination had not been performed. During this period, OCT was performed if written informed consent was given by the patient.…”

“…1) The Z-offset also plays an important role in the accurate measurement and reproducibility of OCT. A 1% change in the magnitude of the ideal Z-offset resulted in a 12-14% error in area measurements by OCT. 19) A clinical study examined the inter-and intraobserver reproducibility of quantitative FD-OCT measurements.…”

Inter-Scan Reproducibility of Geometric Coronary Artery Measurements Using Frequency-Domain Optical Coherence Tomography

SummaryFrequency-domain optical coherence tomography (FD-OCT) is a novel technology which provides high-resolution cross-sectional images of coronary arteries. The aim of this study was to evaluate the inter-scan reproducibility of geometric FD-OCT measurements in the clinical setting. We examined 20 coronary lesions using FD-OCT. Following the FD-OCT image acquisition (1 st pullback), and after the disengagement and re-engagement of the guiding catheter, an additional acquisition (2 nd pullback) was performed using a new FD-OCT catheter. There was excellent correlation for minimum lumen area (r = 0.99, P < 0.001), lesion length (r = 0.99, P < 0.001) and lumen volume (r = 0.99, P < 0.001) between the 1 st pullback and the 2 nd pullback. The Bland-Altman test demonstrated good agreement between the 1 st pullback and the 2 nd pullback: the mean difference for minimum lumen area, lesion length, and lumen volume was 0.05 mm High frame rate (100 frame/sec) and fast pull-back speed (20 mm/s) of FD-OCT allow for a clear visualization of coronary lumens and vessel walls.2,3) Various factors such as location of the image catheter, heart motion, timing of image acquisition (systole/diastole) and manual zero-offset may affect the OCT assessment. 1) In vitro phantom models have demonstrated the accuracy of quantitative OCT measurement for luminal size and length. 4) In a Corelab setting, several studies have disclosed excellent intra-and inter-observer agreement of OCT measurements.5,6) However, the inter-scan reproducibility of geometric OCT measurements remains unclear. Such information in regard to measurement consistency between the scans should be required to design longitudinal OCT studies. The aim of the present study was to assess the inter-scan agreement for geometric FD-OCT measurements in a clinical setting. MethodsStudy population: We enrolled consecutive 20 patients who underwent percutaneous coronary intervention with a single stent for a native coronary artery lesion. Patients were excluded if they had congestive heart failure with a left ventricular ejection fraction < 30 %, renal insufficiency with baseline serum creatinine > 2.0 mg/dL, or required primary angioplasty. In addition, those with left main coronary artery stenting, ostial right coronary artery stenting, or bifurcation stenting were excluded because of expected difficulty in FD-OCT analysis. This protocol was approved by the Wakayama Medical University Ethics Committee, and all patients provided informed consent before participation.
