    1. Optical Coherence Tomography Assessment and Quantification of Intracoronary Thrombus: Status and Perspectives

      Optical Coherence Tomography Assessment and Quantification of Intracoronary Thrombus: Status and Perspectives

      Coronary angiography is the “golden standard” imaging technique in interventional cardiology and it is still widely used to guide interventions. A major drawback of this technique, however, is that it is inaccurate in the evaluation and quantification of intracoronary thrombus burden, a critical prognosticator and predictor of intraprocedural complications in acute coronary syndromes. The introduction of optical coherence tomography (OCT) holds the promise of overcoming this important limitation, as near-infrared light is uniquely sensitive to hemoglobin, the pigment of red blood cells trapped in the thrombus. This narrative review will focus on the use of OCT for the assessment, evaluation ...

    2. Long-term Morphofunctional Remodeling of Internal Thoracic Artery Grafts: A Frequency-Domain Optical Coherence Tomography Study

      Long-term Morphofunctional Remodeling of Internal Thoracic Artery Grafts: A Frequency-Domain Optical Coherence Tomography Study

      Background— Internal thoracic arteries (ITAs) are frequently anastomosed to the coronary circulation for bypass grafting. The purpose of this research was to investigate in vivo the long-term morphofunctional changes of ITAs after their use as coronary artery bypass conduits, by comparing the morphological features and vasoreactivity of the grafted left ITA (LITA) with the native, nonharvested right ITA (RITA) in the same patient. Methods and Results— At least 10 years after surgery, in 10 patients, LITA graft and nonharvested RITA were assessed by quantitative angiography and frequency-domain optical tomography. Endothelium-dependent and independent vasodilation was tested by selective infusion of acetylcholine ...
