title: [Choice of tools for stenting the left coronary artery trunk: a whim or a need?].
abstract: OBJECTIVE
  To study the results of stenting the left coronary artery trunk and to determine the possibility of using Empira dilatation balloon catheters for kissing dilatation.
  
  
  METHODS
  The left coronary artery trunk was stented in 47 patients, which constituted 1.39% of the total number of the stented patients. Bifurcation stenting was performed in 48.9%. T and crush stenting procedures were used in 4 and 2 patients, respectively. Stenting of the left coronary artery trunk with transition to the orifice of the anterior interventricular artery or the circumflex artery was carried out in 12 and 5 patients, respectively.
  
  
  RESULTS
  The angiographic success rate was 100%; there were no fatal outcomes. After endovascular treatment, 20 (42.5%) patients belonged to Functional Class (FC) 0-I angina; 24 (51.1%) and 3 (6.4%) were diagnosed with FC II and III, respectively.
  
  
  CONCLUSIONS
  It was ascertained that it was expedient to use the Empira dilatation balloon catheters for kissing dilatation. The left coronary artery trunk can be successfully stented if the patent is carefully prepared for the intervention.
