TCT-551 Extremely early optical coHerence tOmogRaphy comparative Study among drug Eluting stents with Persistent, absOrbable or Without polymER (HORSEPOWER Study)

The absence of polymer in DES systems may reduce the dual anti-platelet therapy (DAPT) period and the occurrence of late stent thrombosis. However, the sequential changes of stent strut endothelial coverage in the extremely early period have never been reported. This study aimed to assess by optical
