OBJECTIVES: The EVOLVE 48 study evaluated the safety and effectiveness of the SYNERGY 48 mm stent for the treatment of long lesions. BACKGROUND: Clinical evidence supporting the use of very long stents during percutaneous coronary intervention (PCI) is limited. The bioabsorbable polymer SYNERGY stent has shown good long-term data in a broad population of patients undergoing PCI. METHODS: Patients with lesion length >34- ≤44 mm and reference vessel diameter (RVD) ≥2.5- ≤ 4.0 mm were enrolled in this prospective, multicenter, single-arm study. The primary endpoint was 12-month target lesion failure (TLF; composite of target lesion revascularization [TLR], target-vessel myocardial infarction [TV-MI], or cardiac death) compared to a prespecified performance goal (PG). RESULTS: A total of 100 patients with mean lesion length of 35.34 ± 7.15 mm (26 patients with lesion length > 40 mm) and mean RVD 2.72 ± 0.44 mm were enrolled. Moderate to severe calcification was present in 30% of the patients and 89% had pre-TIMI flow grade 3. The rates of technical and clinical procedural success were 100%. One-year TLF was observed in 4.1% patients compared to a prespecified PG of 19.5% (95% upper confidence bound = 9.1%; p
