ABSTRACT

BACKGROUND - Long-term clinical outcomes of permanent polymer everolimus-eluting stent (PP-EES) implantation after rotational atherectomy (RA) have not been fully evaluated. We sought to investigate the long-term clinical outcomes of PP-EES implantation after RA and assess the impact of hemodialysis on this treatment strategy.


METHODS - Patients who underwent percutaneous coronary intervention (PCI) with PP-EES at 22 institutions between January 2010 and December 2011 were enrolled in this multicenter, observational trial. From a total of 1918 registered patients, 113 patients with 115 de-novo lesions who underwent PCI with PP-EES following RA were retrospectively analyzed. The primary endpoint was a major adverse cardiac event (MACE) defined as the composite of cardiac death, non-fatal myocardial infarction (MI), and clinically driven target lesion revascularization (TLR).

RESULTS - Long-term follow-up was available for 112 patients (99.1%). The median follow-up period was 2.9 (interquartile range 1.9-3.6) years. The mean age of the patients was 72.3 ± 8.8 years and 64 patients (56.6%) had chronic kidney disease (≥stage 3, 42 on hemodialysis). The cumulative incidences of MACE, non-fatal MI, and TLR were 22.1%, 5.3%, and 10.6%, respectively. Cox's proportional hazards analysis showed that the independent predictors of TLR were hemodialysis and chronic total occlusion. (HR, 14.1; 95% CI, 1.74-155.5; p = 0.01, HR, 9.01; 95% CI, 1.34-62.5; p = 0.02).

CONCLUSIONS - PP-EES implantation after lesion modification by RA is considered to be a feasible treatment strategy for heavily calcified lesions. Hemodialysis and chronic total occlusion appeared to be associated with TLR.
