title: Contemporary coronary intervention in bifurcation lesions--two-year follow-up in an unselected cohort.
abstract: BACKGROUND
  Optimization of coronary angioplasty in bifurcation lesions remains a major challenge for percutaneous revascularization techniques.
  
  
  METHODS
  We evaluated procedural success, major in-hospital complications, target vessel revascularization, and 2-year clinical outcomes in 45 patients who underwent PTCA of a bifurcation lesion using currently available techniques and rigorous criteria for optimal immediate
  
  
  RESULTS
  Angiographic success occurred in 100% of the parent vessels and in 84.4% of both vessels. Within the first 24 hours, there were no deaths or Q-wave myocardial infarction. Three non-Q-wave myocardial infarctions occurred (6.6%) and one emergency PTCA was necessary (2.2%). Therefore, clinical success was achieved in 91.2% of these patients. At 2-year follow-up, 3 cardiac deaths had occurred, the target revascularization rate was 20%, and the total frequency of major adverse cardiac events (MACE) was 37.8%.
  
  
  CONCLUSIONS
  Optimization of coronary angioplasty in bifurcation lesions is possible and results in a high angiographic success rate, low risk of acute complications and acceptable long-term clinical outcomes. However, the fairly high incidence of MACE at 2 years suggests that bifurcation lesions remain a challenge in everyday practice despite contemporary intervention methods and the use of GPIIb/IIIa inhibitors.
