Clinical outcomes of SeQuent Please paclitaxel-coated balloons for de novo small coronary artery lesion in a Japanese multicenter post-approval registry.

Objective: Drug-coated balloon (DCB) angioplasty has emerged as an effective management strategy worldwide. In June 2016, DCB became available for the treatment of de novo small coronary lesions in Japan; however, there has been no multicenter analysis in a post-approval real-world clinical setting to date. The aim of this study was to evaluate the efficacy of DCB for de novo small coronary lesions based on a Japanese multicenter registry.

Methods And Results: From June 2016 to July 2017, a total of 111 lesions (102 patients) treated with DCB for de novo small coronary lesions were enrolled at six Japanese institutions. The primary endpoint was the rate of target lesion revascularization (TLR) at 12 months. Angiographic follow-up endpoints were binary restenosis and late lumen loss (LLL). Clinical follow-up data at 12 months were available for 106 lesions, excluding five lesions that required bailout stenting. The TLR rate was 5.7% (6/106 lesions). No cardiac death or target lesion thrombosis was observed. The binary restenosis rate was 14.4% and LLL was 0.0017 ± 0.37 mm.

Conclusions: DCB angioplasty for de novo small coronary lesions in the real-world environment in Japan is effective with acceptable 12-month outcomes.
