Purpose Favorable long-term outcomes with the Zilver PTX drug-eluting stent (DES) in treating patients with femoropopliteal lesions have been demonstrated. A multicenter, prospective, post-market surveillance study (PMS) in Japan evaluated this DES in a real-world patient population. Recently, meta-analysis that grouped both DES and drug-coated balloons (DCB) together indicated a higher incidence of late all-cause mortality for paclitaxel- based devices compared to uncoated balloon or bare-metal stent (BMS) at 2 years up to 5 years. To evaluate the long-term safety of the Zilver PTX DES, compared with BMS using Japan-PMS study. Methods The Japan DES PMS had no exclusion criteria and enrolled consecutive patients with symptomatic PAD involving the above-the-knee femoropopliteal arteries. Safety and effectiveness of the DES was evaluated in real-world patients with complex femoropopliteal artery lesions through 5 years. Follow-up in the study is complete. The concurrent Japan BMS PMS also had no exclusion criteria and enrolled consecutive patients with symptomatic PAD involving the above-the-knee femoropopliteal arteries. Patients who were enrolled in the BMS study but who also had a DES placed (n=18) were excluded from the current analysis. Follow-up in the BMS study was only required through 3 years and is complete. Results The Japan DES PMS enrolled 904 DES patients, and the Japan BMS PMS enrolled 190 BMS patients. In the DES group, there were 127 deaths through 3 years and 186deaths through 5 years. In the BMS group, there were 22 deaths through 3 years. Through 3 years, the risk of mortality was 15.7% for DES group and 15.3% for BMS group. Through 5 years, the risk of mortality was 25.8% for the DES group. There was no difference in mortality between the two groups (log-rank p=0.92).The Cox proportional hazards model revealed that CLI (p&amp;lt;0.0001), age (p&amp;lt;0.0001), gender (p=0.001), renal failure (p&amp;lt;0.0001) were significantly associated with mortality. Hypercholesterolemia (p=0.004) was associated with lower risk of mortality. Treatment with Zilver PTX (p=0.49) was not associated with mortality. In the covariate analysis of paclitaxel dose, the significant factors were identical to the treatment analysis, and there was no association or trend of paclitaxel dose (p=0.07) with mortality. Conclusion Analyses of the paclitaxel-coated Zilver PTX DES utilizing patient-level data from the Japan PMS demonstrated no increase in long-term all-cause mortality. The 5-year results from this real-world, all-comers study continue to show positive long-term outcomes and demonstrate the benefit of the Zilver PTX DES across a broad patient population.
