| Popis: | Initial Clinical Results of the First Cobalt-Chromium Stent Designed in Brazil Background: Thin-strut cobalt-chromium stents have greater flexibility and probably have less neointimal proliferation than stainless steel stents. Methods: The Cronus (Scitech Produtos Medicos, Goiânia, Brazil) registry is an international, non-randomized, prospective study designed to evaluate the efficacy and safety of a novel thin-strut cobalt-chromium stent in patients with coronary artery disease. A total of 69 lesions were treated in 53 patients included in this analysis. Results: The device success was 98.5%. Mean late luminal loss was 0.7 ± 0.5 mm, binary restenosis occurred in 15% and target vessel revascularization in 11.3% of the cases. The incidence of major adverse cardiac events (death, myocardial infarction or target vessel revascularization) was 24.4% after 317 ± 80 days of follow-up. Conclusion: Our initial results demonstrate that the novel Cronus stent proved to be safe and effective, with clinical results similar to other available thin-strut stents. DESCRIPTORS: Stents. Angioplasty, transluminal, percutaneous coronary. Prostheses and implants. |
