ABSTRACT Background: To evaluate the safety and efficacy of the EndeavorTM-Stent-Stent (Medtronic Corp., USA) in daily practice. Material and methods: Data come from a prospective single-centre registry. Between 2005 and 2007 all patients, who received at least one Endeavor? coronary stent, were included into a registry. Patients were contacted after 12 and 24 - 36 months. Results: 326 patients (97 females, mean age 67.5 ± 10.3 years) were included. From these patients 137 (42%) had a 3-vessel disease, 96 (29%) presented with myocardial infarction ≤ 72 hrs, 19 (6%) with a left ventricular ejection fraction < 25%. In summary, 379 lesions (50% type B2, 23% type C, mean lesion length 20.2 ± 10.0 mm, mean reference vessel diameter 3.0 ± 0.4 mm) were treated with EndeavorTM-Stent-Stents. Per patient, 0.4 ± 0.7 bare metal stents were implanted. Median follow-up time was 35.3 months, during follow-up 165 patients (50.6%) had repeated angiography. After 12 (24) months overall mortality was 5.8% (7.3%), cardiac mortality 3.1% (3.5%), myocardial infarction rate 1.5% (4.1%), target-vessel revascu-larization rate 8.7% (12.4%), target-lesion revascu-larization rate 6.1% (8.4%), and cumulative MACE-rate 14.1% (21.9%). In total, 2 definite or likely stent-thromboses (0.6%) occurred during follow-up. Logistic regression revealed the treatment of saphenous vein grafts and aorto-coronary ostial lesions as risk factors for target lesion revascularization. Conclusion: The EndeavorTM-Stent-Stent is a safe and effective drug-eluting stent in the treatment of daily-life coronary patients. Treatment of vein grafts and aorto-coronary ostial lesions appear to be associated with a higher need for re-interventions.
