Optical coherence tomography (OCT) has been reported as promising not only for the evaluation of lesion morphology, but also for better clinical outcomes; however, in some cases with severe vessel tortuosity or angulated bifurcation, it is difficult to advance an intravascular imaging catheter. We report a case in which a GuideLiner® catheter facilitated obtaining better angiographic and OCT images with the sub-selective injection of minimal contrast medium, even in a case with a tortuous vessel or angulated bifurcation. Furthermore, OCT assessment of a vessel through the catheter may be other potential advantage of this device.
