Healing of floating unapposed drug eluting stent struts: insights from 3D optical coherence tomography
Pathological evidence suggests that coverage of malapposed struts in Drug Eluting Stents is necessary to limit risks of late and very late stent thrombosis. In this case report, the coverage of the struts left unapposed in bifurcations using 3D Optical Coherence Tomography is illustrated. The follow-up with optical coherence tomography (OCT) suggests that struts which were left unapposed at the ostium become covered with a thick layer of tissue, which differs from the thin coverage found on well-apposed struts. Questions are raised as to whether such coverage is able to functionally isolate the metallic struts left unapposed and eliminate the ...
