Why the study?
Small randomized trials showed PCB angioplasty was superior to uncoated balloon angioplasty for BMS and DES restenosis, but large-scale international safety and efficacy data were needed.

In a large, prospective, international registry, paclitaxel-coated balloon angioplasty demonstrated low rates of target lesion revascularization, confirming findings from smaller randomized trials.
OBJECTIVES: This study sought to assess the safety and efficacy of paclitaxel-coated balloon (PCB) angioplasty in an international, multicenter, prospective, large-scale registry study. BACKGROUND: In small randomized trials, PCB angioplasty was superior to uncoated balloon angioplasty for treatment of bare-metal stent (BMS) and drug-eluting stent (DES) restenosis. METHODS: Patients treated with SeQuent Please PCBs were included. The primary outcome measure was the clinically driven target lesion revascularization (TLR) rate at 9 months. RESULTS: At 75 centers, 2,095 patients with 2,234 lesions were included. The TLR rate was 5.2% after 9.4 months. Definite vessel thrombosis occurred in 0.1%. PCB angioplasty was performed in 1,523 patients (72.7%) with DES or BMS restenosis and 572 patients (27.3%) with de novo lesions. The TLR rate was significantly lower in patients with PCB angioplasty for BMS restenosis compared with DES restenosis (3.8% vs. 9.6%, p < 0.001). The TLR rate did not differ for PCB angioplasty of paclitaxel-eluting stent and non-paclitaxel-eluting sten restenosis (8.3% vs. 10.8%, p = 0.46). In de novo lesions (small vessels), the TLR rate was low and did not differ between PCB angioplasty with and without additional BMS implantation (p = 0.31). CONCLUSIONS: PCB angioplasty in an all-comers, prospective, multicenter registry was safe and confirmed in a large population the low TLR rates seen in randomized clinical trials. PCB angioplasty was more effective in BMS restenosis compared with DES restenosis, with no difference regarding the type of DES.

Wöhrle et al. (2012) conducted an observational in In-stent restenosis and de novo coronary lesions (n=2,095). Paclitaxel-coated balloon (PCB) angioplasty was evaluated on clinically driven target lesion revascularization (TLR) rate at 9 months.
