Objective : To evaluate technical feasibility and procedural safety of SLK‐View™ stent for treating bifurcation lesions. Background : Percutaneous treatment of coronary bifurcation lesions represents a technical challenge. Several stenting techniques and dedicated devices have proven unsuccessful, with high rates of side branch occlusion at index procedure and follow‐up. Methods : Eighty one patients with 84 de novo coronary artery lesions involving a major side branch underwent SLK‐View™ (Advanced Stent Technologies, Inc., Pleasanton, CA) stent implantation with subsequent kissing balloon post dilatation. SLK‐View™ stent is a new scaffolding device incorporating a side aperture that allows access to the side‐branch of a bifurcation after deployment of the stent in main vessel. All patients underwent angiographic follow‐up at 6 months. Procedural, in‐hospital, and 6‐month follow‐up outcomes were examined. Results : The lesions were located in left main ( n = 11), left anterior descending ( n = 50), left circumflex ( n = 8), right coronary artery ( n = 7), and 1 ramus intermedius. The most frequent lesions (44.1%) were true bifurcations. Successful stent delivery to bifurcation was accomplished in 82/84 of the cases (97.6%). Technical success was obtained in 99 and 94% of main vessel and side branches, respectively. Stenting in side‐branch was performed in 21 lesions (25%). Side‐branches were accessed effectively in 100% of bifurcations postprocedurally. Binary restenosis rate at 6‐month follow‐up was 28.3% and 37.7% for main vessel and side‐branch, respectively. TLR rate at 6‐month follow‐up was 21% and CABG rate of 6%. Conclusion : In this consecutive multicenter series of patients with coronary bifurcation lesions, this novel side‐branch access stent proved feasible, with a high procedural success rate, while maintaining side‐branch access. © 2006 Wiley‐Liss, Inc.
