[Comment] Optical coherence tomography: not quite ready
Intravascular imaging has revolutionised the way coronary intervention has been viewed. Both intravascular ultrasound (IVUS) and, to a greater degree, optical coherence tomography (OCT), allow exquisite assessment of the luminal wall and structure to a near-histological tissue assessment level. OCT also allows detailed assessment of stent characteristics and, in particular, of adequacy of deployment and early identification of procedural complications, such as edge dissections. Although this level of imaging provides invaluable information for the interventionalist, data are scarce for its use in clinical practice to improve outcomes.
