    Abstract:
    BACKGROUND: Although drug-coated balloon (DCB)-based stent-less percutaneous coronary intervention (PCI) for de-novo lesions has attracted more attention, outcomes of the DCB procedure for hemodialysis (HD) patients are reported to be inferior to those for non-HD patients, similarly to drug-eluting stent (DES). Recent several reports have shown that rotational atherectomy (RA) followed by DCB treatment (RA/DCB) could be an option of revascularization strategy particularly for calcified de-novo lesions even in the new-generation DES era; however, efficacy of the RA/DCB procedure for HD patients remains unclear. METHODS: A total of 47 consecutive cases (53 lesions) undergoing RA/DCB for de-novo lesions were enrolled. According to the presence/absence of HD at baseline, the 47 cases were divided into the HD cases (N.=16) and the non-HD cases (N.=31), and the 53 lesions were divided into the HD lesions (N.=20) and the non-HD lesions (N.=33). RESULTS: The HD cases had a significantly lower prevalence of dyslipidemia and smoking than the non-HD cases. Final RA burr size, DCB diameter used, and angiographic success rate of PCI did not significantly differ between the 2 groups. Preprocedural, post-procedural, and follow-up QCA parameters were also similar between the 2 groups. Twelve-month clinical outcomes were comparable between the 2 groups. CONCLUSIONS: Mid-term outcomes of stent-less PCI using RA/DCB for de-novo lesions in HD patients might be comparable to those in non-HD patients, suggesting efficacy of pretreatment of RA prior to DCB treatment in HD patients.
