Three-Year Clinical Outcome of Patients with Coronary Disease and Increased Event Risk Treated with Newer-Generation Drug-Eluting Stents: From the Randomized DUTCH PEERS Trial

Long-Term Outcome of Drug-Coated Balloon vs Drug-Eluting Stent for Small Coronary Vessels: PICCOLETO-II 3-Year Follow-Up

BACKGROUND

Native vessel coronary artery disease represents 1 of the most attractive fields of application for drug-coated balloons (DCBs). To date, several devices have been compared with drug-eluting stents (DESs) in this setting with different outcomes.

OBJECTIVES

The authors sought to compare the short- and long-term performance of the paclitaxel DCB with the everolimus-eluting stent in patients with de novo lesions in small coronary vessel disease.

METHODS

PICCOLETO II (Drug Eluting Balloon Efficacy for Small Coronary Vessel Disease Treatment) was an academic, international, investigator-driven, multicenter, open-label randomized clinical trial in which patients were allocated to a DCB (n = 118) or DES (n = 114). We previously reported the superiority of DCBs regarding in-lesion late lumen loss at 6 months. Herein we report the final 3-year clinical follow-up with the occurrence of major adverse cardiac events (MACEs), a composite of cardiac death, nonfatal myocardial infarction, target lesion revascularization, and its individual components.

RESULTS

The 3-year clinical follow-up (median 1,101 days; IQR: 1,055-1,146 days) was available for 102 patients allocated to DCB and 101 to DES treatment. The cumulative rate of all-cause death (4% vs 3.9%; P = 0.98), cardiac death (1% vs 1.9%; P = 0.56), myocardial infarction (6.9% vs 2%; P = 0.14), and target lesion revascularization (14.8% vs 8.8%; P = 0.18) did not significantly differ between DCBs and DESs. MACEs and acute vessel occlusion occurred more frequently in the DES group (20.8% vs 10.8% [P = 0.046] and 4% vs 0% [P = 0.042], respectively).

CONCLUSIONS

The long-term clinical follow-up of the PICCOLETO II randomized clinical trial shows a higher risk of MACEs in patients with de novo lesions in small vessel disease when they are treated with the current-generation DES compared with the new-generation paclitaxel DCB.

Safety and effectiveness of zotarolimus-eluting stents for percutaneous coronary intervention: a systematic review

Drug-eluting stents revolutionized the treatment of coronary artery disease with vastly improved outcomes compared with bare metal stents. As stent technology has evolved, a wide variety of antiproliferative drugs have been developed to prevent stent restenosis and stent thrombosis. The Resolute stent system (Medtronic, CA, USA) elutes zotarolimus from a multipolymer blend to prevent early and late stent-related complications. The Resolute stents have evolved from the initial Resolute stent, to the Resolute Integrity™ and most recently, the Resolute Onyx™. These stents have been studied across a wide range of patients and coronary syndromes. They compare similarly in performance to their contemporary second generation stents. We present a review of the major trials involving these zotarolimus-eluting stents.
