Long-term tissue coverage of a biodegradable polylactide polymer-coated biolimus-eluting stent: Comparative sequential assessment with optical coherence tomography until complete resorption of the polymer

More complete strut coverage of BES as compared with SES at 9 months was followed by improvement of coverage in SES between 9 and 24 months and a similar long-term coverage in both stent types at 24 months.
