Objectives: This final report from the REMEDEE Registry assessed the long-term safety and efficacy of the dual-therapy COMBO stent in a large unselected patient population. Background: The bio-engineered COMBO stent (OrbusNeich Medical BV, The Netherlands) is a dual-therapy pro-healing stent. Data of long-term safety and efficacy of the this stent is lacking. Methods: The prospective, multicenter, investigator-initiated REMEDEE Registry evaluated clinical outcomes after COMBO stent implantation in daily clinical practice. One thousand patients were enrolled between June 2013 and March 2014. Results: Five-year follow-up data were obtained in 97.2% of patients. At 5-years, target lesion failure (TLF) (composite of cardiac death, target-vessel myocardial infarction, or target lesion revascularization) was present in 145 patients (14.8%). Definite or probable stent thrombosis (ST) occurred in 0.9%, with no additional case beyond 3-years of follow-up. In males, 5-year TLF-rate was 15.6 versus 12.6% in females (p =.22). Patients without diabetes mellitus (DM) had TLF-rate of 11.4%, noninsulin-treated DM 22.7% (p =.001) and insulin-treated DM 41.2% (p <.001). Patients presenting with non-ST segment elevation acute coronary syndrome (NSTE-ACS) had higher incidence of TLF compared to non-ACS (20.4 vs. 13.3%; p =.008), while incidence with STE-ACS was comparable to non-ACS (10.7 vs. 13.3%; p =.43). Conclusion: Percutaneous coronary intervention with the dual-therapy COMBO stent in unselected patient population shows low rates of TLF and ST to 5 years. Remarkably, no case of ST was noted beyond 3 years.
