N2 - BACKGROUND: Numerous randomized clinical trials have demonstrated the superiority of thin-strut biodegradable polymer second-generation drug-eluting stent to the first-generation drug-eluting stent and the noninferiority to the thin-strut second-generation permanent polymer drug-eluting stent. Data on long-term clinical outcomes with a novel ultrathin drug-eluting stent, to date, are limited. METHODS: The DESSOLVE III trial (Multicenter Randomized Study of the MiStent Sirolimus Eluting Absorbable Polymer Stent System for Revascularization of Coronary Arteries; n=1398) is a prospective, multicenter, single-blinded, all-comers, randomized controlled trial (NCT02385279), allocating in a 1:1 ratio to either ultrathin-strut biodegradable polymer MiStent sirolimus-eluting stent or to thin-strut permanent polymer Xience everolimus-eluting stent. The primary end point was device-oriented composite end point, defined as the composite of cardiac death, target vessel myocardial infarction, or clinically indicated target lesion revascularization. The secondary end point was patient-oriented composite end point, defined as the composite of all-cause mortality, any myocardial infarction, or any revascularization. RESULTS: At 3 years, follow-up data were available in 1381 patients (98.8%). The primary end point of device-oriented composite end point occurred in 10.5% for MiStent sirolimus-eluting stent and in 11.5% for Xience everolimus-eluting stent (P=0.55). Rates of cardiac death (3.9% versus 3.8%; P=0.88), target vessel myocardial infarction (3.2% versus 2.5%; P=0.43), and clinically indicated target lesion revascularization (5.2% versus 6.5%; P=0.30) did not differ significantly between the 2 devices. The rate of definite or probable stent thrombosis was infrequent and similar between the 2 arms (1.2% versus 1.5%; P=0.64). The 90-day landmark analysis showed no significant difference in device-oriented composite end point between the 2 groups after polymer degradation of MiStent. The risk of patient-oriented composite end point was comparable between the 2 groups (22.7% versus 22.9%; P=0.34). CONCLUSIONS: In the DESSOLVE III trial, early safety and efficacy with MiStent sirolimus-eluting bioabsorbable polymer-coated stent are confirmed at a longer term follow-up when compared with Xience everolimus-eluting permanent polymer-coated stent in a large all-comers population.
