Background. The Agent paclitaxel-coated balloon is a new drug-coated balloon (DCB) with few available real-world data. Our study sought to assess the safety and efficacy of the Agent DCB during percutaneous coronary intervention (PCI) in different coronary lesion types in a prospective registry. Methods and Results. All patients undergoing PCI with the Agent DCB at three Italian centers between September 2014 and March 2018 were included in this registry. Major adverse cardiac event (MACE) rate was defined as the composite of cardiac death, recurrent non-fatal myocardial infarction (MI), and target-lesion revascularization (TLR). Procedural success was also evaluated. Among the 354 patients included in the registry (450 lesions treated with 508 DCBs), Agent DCBs were used for the treatment of in-stent restenosis (ISR) in 34%, small-vessel disease (SVD) in 29%, bifurcation lesions in 26%, and “stent-like result” (SLR) lesions obtained after balloon predilation in 11%. The implantation of Agent DCBs was safe and had a high DCB lesion success rate of 92%. One-year MACE rate was 5.7% in the overall population. A higher MACE rate was observed in the ISR group (8.3%) vs the SVD group (3.6%; P=.03), with a trend toward higher event rates vs both BL (3.7%; P=.09) and SLR patients (5.5%; P=.54). Conclusions. The use of Agent DCBs during PCI appears safe and effective in a large real-world registry. These results were maintained in all subgroups, with a slightly higher trend of events rates in the ISR setting, consistent with the higher-risk nature of this patient subset.

Abstract
Background. The Agent paclitaxel-coated balloon is a new drug-coated balloon (DCB) with few available real-world data. Our study sought to assess the safety and efficacy of the Agent DCB during percutaneous coronary intervention (PCI) in different coronary lesion types in a prospective registry. Methods and Results. All patients undergoing PCI with the Agent DCB at three Italian centers between September 2014 and March 2018 were included in this registry. Major adverse cardiac event (MACE) rate was defined as the composite of cardiac death, recurrent non-fatal myocardial infarction (MI), and target-lesion revascularization (TLR). Procedural success was also evaluated. Among the 354 patients included in the registry (450 lesions treated with 508 DCBs), Agent DCBs were used for the treatment of in-stent restenosis (ISR) in 34%, small-vessel disease (SVD) in 29%, bifurcation lesions in 26%, and “stent-like result” (SLR) lesions obtained after balloon predilation in 11%. The implantation of Agent DCBs was safe and had a high DCB lesion success rate of 92%. One-year MACE rate was 5.7% in the overall population. A higher MACE rate was observed in the ISR group (8.3%) vs the SVD group (3.6%; P=.03), with a trend toward higher event rates vs both BL (3.7%; P=.09) and SLR patients (5.5%; P=.54). Conclusions. The use of Agent DCBs during PCI appears safe and effective in a large real-world registry. These results were maintained in all subgroups, with a slightly higher trend of events rates in the ISR setting, consistent with the higher-risk nature of this patient subset.
