Neointimal Coverage on Drug-Eluting Stent Struts Crossing Side-Branch Vessels Using Optical Coherence Tomography
The status of neointimal coverage on the drug-eluting stent (DES) struts, which are placed across the side-branch vessels, remains unclear. The degree of neointimal coverage of stent struts crossing the side-branch vessel was evaluated according to the different types of DESs. Follow-up optical coherence tomography images at 9.3 months after the index procedure were identified in 51 patients who had undergone DES (sirolimus-eluting stents [SESs] in 22 patients, paclitaxel-eluting stents [PESs] in 15, and zotarolimus-eluting stents [ZESs] in 14) implantation with crossover of the side-branch vessels (size >2.0 mm). The enrolled patients were classified as a covered group ...
