      Influence of neoatherosclerosis on prognosis and treatment response in patients with in-stent restenosis
      Introduction and objectives Neoatherosclerosis is one of the causes of in-stent restenosis (ISR). Our objective was to evaluate the influence of neoatherosclerosis on prognosis and treatment response in patients with ISR. Methods This is a pooled analysis of the optical coherence tomography (OCT)-substudies of 2 multicenter, randomized clinical trials, RIBS IV and V, comparing treatment with paclitaxel-coated balloon vs everolimus-eluting stent in patients with ISR. OCT evaluation was performed ...

      Longitudinal Stent Deformation: Precise Diagnosis With Optical Coherence Tomography
      Longitudinal stent deformation (LSD), defined as the distortion or shortening of a stent in the longitudinal axis following successful stent deployment, has been recognized as an important complication of coronary angioplasty. It is caused by impact on a deployed stent by a device (such as a guide catheter or guide-catheter extension) or secondary devices (such as postdilation balloons) as a result of guidewire bias as well as the inherent mechanical ...

      Optical coherence tomography probe for crossing coronary occlusions
      Systems and methods for controlling a guide with the aid of optical coherence tomography (OCT) data are described. A guide wire includes at least one optical fiber, a flexible substrate, and one or more optical elements. The at least one optical fiber transmits a source beam of radiation. The flexible substrate includes a plurality of waveguides. At least one of the plurality of waveguides transmits one or more beams of ...

      Radiofrequency ablation catheter with optical tissue evaluation
      Systems and methods for performing RF ablation while monitoring the procedure using low coherence interferometry (LCI) data are described. A catheter includes a distal section, a proximal section, a multiplexer, and a sheath coupled between the distal section and the proximal section. The distal section includes several interconnected optical ports configured to transmit exposure radiation toward a sample and receive radiation that have been reflected or scattered from the sample ...

      Novel catheter enabling simultaneous radiofrequency ablation and optical coherence reflectometry
      A novel radiofrequency ablation catheter has been developed with integrated custom designed optics, enabling real-time monitoring of radiofrequency ablation procedures through polarization-sensitive optical coherence reflectometry. The optics allow for proper tissue illumination through a view-port machined in the catheter tip, thus providing lesion depth control over the RF ablation treatment. The system was verified in an in-vitro model of swine myocardium. Optical performance and thermal stability was confirmed after more ...

      Calcified Nodule Mimicking Red Thrombus on Optical Coherence Tomography
      The single case report by Hao et al. 1 describing the unique pathological microstructure of a calcified nodule (CN) in an 89-year-old woman dying of congestive heart failure provides unique clues to advance our ability to interpret the images provided by intracoronary diagnostic techniques. The beauty of this report is that a detailed pathological analysis of the CN was combined with corresponding intravascular ultrasound (IVUS), optical coherence tomography (OCT), and ...

      Utility of optical coherence tomography and intravascular ultrasound for the evaluation of coronary lesions
      Optical coherence tomography (OCT) and intravascular ultrasound (IVUS) are imaging methods used in the diagnosis of coronary lesions. IVUS is widely used in interventional cardiology laboratories, but OCT is now increasingly used. Conventional coronary angiography can identify different types of coronary lesions but sometimes is unable to diagnose them correctly. Both intravascular imaging methods are useful for better interpretation of these lesions, and can accurately diagnose ruptured plaques, thrombosis, stent ...

      Renal artery fibromuscular dysplasia: in vivo optical coherence tomography insights
      A 66-year-old woman with long-term essential hypertension presented with poorly controlled blood pressure in spite of six antihypertensive drugs. Percutaneous renal denervation was indicated as a treatment of resistant arterial hypertension. Renal angiography showed strings of beads appearance characteristic of fibromuscular dysplasia (FMD) in the mid-segment of the right

      A 3D edge detection technique for surface extraction in computed tomography for dimensional metrology applications
      Many factors influence the measurement uncertainty when using computed tomography for dimensional metrology applications. One of the most critical steps is the surface extraction phase. An incorrect determination of the surface may significantly increase the measurement uncertainty. This paper presents an edge detection method for the surface extraction based on a 3D Canny algorithm with sub-voxel resolution. The advantages of this method are shown in comparison with the most commonly ...

      Utility of Optical Coherence Tomography to Assess a Hazy Intracoronary Image after Percutaneous Coronary Intervention
      Although its use in daily practice is not common, optical coherence tomography (OCT) is a powerful research tool in invasive cardiology. This report describes a hazy angiography image after percutaneous coronary intervention that has been assessed using OCT. Based on the results of the OCT, the patient underwent an elective coronary angioplasty with standard anticoagulation. After implantation of the stent, an intracoronary hazy image was seen on angiography. The use ...
