Suboptimal stent deployment is associated with subacute stent thrombosis: Optical Coherence Tomography insights from a multicenter matched study. From the CLI Foundation investigators: the CLI-THRO study
Background Acute or sub-acute stent thrombosis (ST) is a well described complication usually causing acute coronary syndromes (ACS) and in the worst case scenario sudden cardiac death. In this study we aimed at exploring the potential role of optical coherence tomography (OCT) in the understanding of the mechanism of ST. Methods Twenty-one consecutive patients, after ACS due to a definite sub-acute ST, were assessed with OCT and matched 1:2 with 42 patients undergoing OCT for scheduled follow-up. OCT assessment was focused on features indicative of non-optimal stent deployment: under-expansion, malapposition, edge dissection and reference lumen narrowing. Results OCT revealed ...
