Summary:Introduction: We aimed to evaluate the safety and efficacy of the simpax stent in the treatment of different patient groups. Patients and Methods: Forty-five patients were treated with the simpax stent. Of these patients, 23 patients gave consent for six months of follow-up by quantitative coronary angiography (QSA) and six patients were evaluated by exercise electrocardiographic test. Only the patients having lesions with stenosis > 50% of diameter and lengths > 16 mm with reference diameters < 2.75 mm were included. Results: The device success rate was 100% and procedure success rate was 97.7%. The mean stent length was 24.6 ± 7.3 mm and stent size was 2.54 ± 0.24 mm. The overall six months incidence of major adverse cardiac events (MACE) was 8.8%. MACE was consisted of two cases of non-Q wave myocardial infarction and two cases of repeated revascularization of the target lesion. MACE rate was higher in chronic total occlusion (CTO) group than non-CTO group (respectively 33.3% and 5.1). Also when compared to stent size, MACE rate was 25% in < 2.5 mm, 0% ? 2.5 mm. The QSA results at six months showed in-stent late lumen loss witha diameter of 0.25 ± 0.15 mm in 17 patients. Conclusion: The six month results in this study demonsrated excellent procedural and device success. Simpax stent was associated with a low in-stent late lumen loss. Also this study showed simpax stent was a safe and effective device in non-CTO group with stent size ? 2.5 mm. Giriş: Bu çalışmadaki amacımız farklı hasta gruplarında simpax stentin etkinliği ve güvenilirliğini değerlendirmektir. Hastalar ve Yöntem: Kırk beş hasta simpax stent ile tedavi edildi. Altı aylık takipte 23 hasta kantitatif koroner anjiyografi (QSA) ve altı hasta egzersiz elektrokardiyografi testiyle değerlendirildi. Çalışmaya > %50 çap daralması olan ve uzunluğu > 16 mm ile referans damar çapı < 2.75 mm olan hastalar dahil edildi.Bulgular: Cihaz başarı oranı %100, prosedür başarı oranı %97.7 idi. Ortalama stent uzunluğu 24.6 ± 7.3 mm ve stent çapı 2.54 ± 0.24 mm idi. Altı aylık majör istenmeyen kardiyak olayların (MACE) genel insidansı %8.8 olarak bulundu. MACE oranı kronik total oklüzyon (KTO) grubunda KTO olamayan gruba göre daha fazlaydı (sırasıyla %33.3 ve %5.1). Ayrıca, stent çaplarına göre karşılaştırıldığında, MACE oranı çapı < 2.5 mm olan stentlerde %25; > 2.5 mm olan stentlerde %0 olarak bulundu. On yedi hastadaki altıncı ay QSA sonuçları stent içi geç lümen kaybını 0.25 ± 0.15 mm olarak gösterdi. Sonuç: Çalışmanın altı aylık sonuçlarına göre prosedür ve cihaz başarı oranı mükemmeldi. Simpax stent düşük stent içi geç lümen kaybı ile ilişkili bulunmuştur. Ayrıca bu çalışma simpax stentin, kronik total oklüzyonu olmayan ve stent çapı > 2.5 mm olan grupta güvenli ve etkili olduğunu gösterdi
