“…1 In contrast, organized thrombi and fibrinoids, markers of delayed healing, are often found in the ISR tissue of DES. 5-7,27, 28 In terms of optical properties, NIT rich in smooth muscle cells with regeneration of dense collagen fibers has high backscatter to optical waves and shows high optical intensity, whereas NIT rich in proteoglycans, cell matrix, and fibrinoids with a low density of smooth muscle cells has a low intensity because of high absorption and multiple scattering of optical waves or low backscattering from penetrating light. 29, 30 Indeed, results from the present investigation clearly demonstrated that BMS restenosis tissue had a significantly higher mean signal intensity with lower attenuation than DES restenosis tissue.…”

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.
