The drug-coated balloon (DCB) is an attractive alternative to a drug-eluting stent (DES) for in-stent restenosis (ISR)1 and de novo small vessels2. However, the large profiles of DCBs make drug delivery to the lesion difficult. Because the additive effect of DCB over a plain balloon is derived only from the antiproliferative drug3, we hypothesised that the adjunctive use of a guide extension catheter (GEC) might enhance the efficacy of the DCB by preventing drug loss and improve the clinical outcomes.


This before-and-after cohort study included patients who underwent DCB angioplasty at Ogaki Municipal Hospital. ...
