Angiographic and clinical one-year follow-up of the Cordis tantalum coil stent in a multicenter international study demonstrating improved restenosisrates when compared to pooled PTCA and BENESTENT-I data: The European Antiplatelet Stent Investigation (EASI)

The Cordis tantalum coil stent was assessed in a nonrandomized multicenter trial: 275 patients with stable or unstable angina were entered. Clinical f ollow-up was for 1 year, with repeat angiography at 6 months. The major adv erse cardiac event rates (MACE) were 3%, 14%, and 17% at 1, 7, and 13 month s, respectively. The procedural success rate was 96% and the subacute occlu sion rate 1.5%, in a group of patients over 60% of whom had ACC/AHA type B2 or C lesions. The binary restenosis rate at 6 months was 17.3%. Minimum lu men diameter increased from 1.07 +/- 0.28 mm preprocedure to 2.93 +/- 0.34 mm poststenting and at 6 months was 1.99 +/- 0.69 mm. These results demonst rate that the Cordis tantalum stent can be used to treat complex lesions wi th good procedural success and tow rates of subacute thrombosis and resteno sis at 6 months.
