[en] AIMS: To prospectively evaluate the influence of stent length on 6 month clinical and angiographic outcome, in patients with native coronary lesions up to 45 mm in length, undergoing elective Magic Wallstent implantation. METHODS AND RESULTS: On the basis of pre-procedural angiography, 276 patients (aged 61.3+/-10.2 years; 78.6% male; 41.7% unstable angina) with a total of 302 lesions were prospectively assigned to one of five different length categories of Magic Wallstent. Angiography in multiple matched projections before and after implantation and at 6 months follow-up was analysed at the core laboratory. Primary end-points for the efficacy analysis were cumulative incidence of major adverse cardiac events and quantitative coronary angiography analysis 6 months after stent implantation. Magic Wallstent implantation was successful in 301 of 302 lesions and in 98.6% a residual stenosis <20% by online quantitative coronary angiography was achieved. At 30 days, 6.2% (1.8% subacute occlusion) of patients had experienced major adverse cardiac events, 27.5% at 6 months and 30.4% at 9 months. Angiographic restenosis occurred in 37%. Restenosis rates for the mini, extra-short, short, medium and long Wallstent groups were 25.9%, 25%, 22.6%, 36.2% and 67.5%, respectively. Multivariate analysis revealed stent length to be independently associated with greater angiographic restenosis and major adverse cardiac events. CONCLUSIONS: While shorter Magic Wallstents provided late outcomes comparable with short balloon-expandable stents, excessive restenosis with longer Wallstents should obviate their use in elective percutaneous intervention. Long coronary lesions provide a challenging substrate for emerging antirestenosis therapies, such as stent coatings and brachytherapy.
