    Comparison of Iodixanol and Ioxaglate for Coronary Optical Coherence Tomography Imaging

    Background. The impact of contrast type on coronary imaging using optical coherence tomography (OCT) has received limited study. We compared OCT imaging obtained using the non-ionic, iso-osmolar iodixanol with the ionic, low-osmolar ioxaglate. Methods. Twenty-two vessels in 20 patients were imaged twice using manual injection of iodixanol and ioxaglate in random order. OCT images were analyzed at 1 mm intervals to determine lumen area, artifact diameter and area, as well as stent strut coverage and malapposition in OCT pullbacks that included stents. Results. There were no complications related to OCT imaging or to contrast administration. A total of 2184 cross-sections ...
