    • AIMS: The risk of stent thrombosis has been reported to increase with percutaneous coronary intervention (PCI) complexity. The present study reports the pre-specified secondary endpoint of a 14-month stent thrombosis and major adverse cardiac events in patients stented with a simple versus a complex bifurcation technique using sirolimus eluting stents (SES). METHODS AND RESULTS: A total of 413 patients with a coronary bifurcation lesion were randomised to a simple treatment strategy; stenting of main vessel and optional stenting of side branch (MV group), or to a complex stenting strategy; stenting of both main vessel and side branch (MV+SB group). Mortality data were available in all patients and 14-month clinical follow-up data in 395 (96%) of the patients. After 14 months, the rates of definite, probable and possible stent thrombosis (ARC criteria) were 1.0% vs. 0.5%, 1.0% vs. 0% and 0.5% vs. 0% (ns) in the MV and in the MV+SB groups, respectively. Rates of MACE were 9.5% in the MV group and 8.2% in the MV+SB group (ns). Total death was seen in 2.4% vs. 1.0% and non-PCI related myocardial infarction in 2.0% vs. 1.0% in the MV and the MV+SB groups, respectively. CONCLUSIONS: After 14 months, two months after recommended cessation of dual antiplatelet therapy, the rates of stent thrombosis and major adverse cardiac events were low and independent of treatment complexity in patients treated with SES for coronary artery bifurcation lesions.

  • Randomized study on simple versus complex stenting of coronary artery bifurcation lesions : the Nordic bifurcation study
  • 2006
  • Ingår i: Circulation. - 0009-7322 .- 1524-4539. ; 114:18, s. 1955-1961

    • Background - The optimal stenting strategy in coronary artery bifurcation lesions is unknown. In the present study, a strategy of stenting both the main vessel and the side branch ( MV + SB) was compared with a strategy of stenting the main vessel only, with optional stenting of the side branch ( MV), with sirolimus-eluting stents. Methods and Results - A total of 413 patients with a bifurcation lesion were randomized. The primary end point was a major adverse cardiac event: cardiac death, myocardial infarction, target-vessel revascularization, or stent thrombosis after 6 months. At 6 months, there were no significant differences in rates of major adverse cardiac events between the groups ( MV + SB 3.4%, MV 2.9%; P = NS). In the MV + SB group, there were significantly longer procedure and fluoroscopy times, higher contrast volumes, and higher rates of procedure-related increases in biomarkers of myocardial injury. A total of 307 patients had a quantitative coronary assessment at the index procedure and after 8 months. The combined angiographic end point of diameter stenosis > 50% of main vessel and occlusion of the side branch after 8 months was found in 5.3% in the MV group and 5.1% in the MV + SB group ( P = NS). Conclusions - Independent of stenting strategy, excellent clinical and angiographic results were obtained with percutaneous treatment of de novo coronary artery bifurcation lesions with sirolimus-eluting stents. The simple stenting strategy used in the MV group was associated with reduced procedure and fluoroscopy times and lower rates of procedure-related biomarker elevation. Therefore, this strategy can be recommended as the routine bifurcation stenting technique.
