Abstract
Treatment of bifurcation lesions is associated with high procedural complications and restenosis rate due to plaque shift, suboptimal angiographic results, difficulty in crossing the stent struts, and incomplete coverage of the side‐branch ostium. The simultaneous kissing stent (SKS) technique involves two stents, one in main vessel (MV) and one in the side branch (SB) with overlapping stents in the MV proximally, extending proximally the carina of bifurcation. We analyzed our first 200 consecutive patients (202 lesions) who underwent SKS technique for true bifurcation lesions using sirolimus eluting stents, with a minimum follow‐up of 6 months. Procedural success was 100% for MV and 99% for SB using SKS technique, with clinical success rate of 97%. In‐hospital and 30‐day major adverse cardiac events were 3% and 5%, respectively, with a procedure time of 36 ± 14 min. At mean follow‐up of 9 ± 2 months, the incidence of target lesion revascularization was 4% in the entire group. Therefore, SKS technique using sirolimus‐eluting stents may become an effective treatment strategy for large‐size bifurcation lesions. However, in order to establish its superiority, SKS technique needs to be compared in a randomized manner with conventional stent techniques.
