title: [Clinical outcome of patients undergoing emergent coronary artery bypass grafting following failed percutaneous coronary intervention in stent era].
abstract: OBJECTIVE
  To explore clinical outcomes of patients undergoing emergent coronary artery bypass grafting (CABG) following failed percutaneous coronary intervention (PCI) in the stent era.
  
  
  METHODS
  Eleven patients who underwent emergent CABG following failed PCI from January, 2002 to December 2010 were enrolled. The in-hospital follow-up included cardiac deaths, Q-wave myocardial infarction, kidney failure, and cerebrovascular events. The clinical end-point of out-hospital follow-up was the major adverse cardiac events including death, myocardial infarction, and target lesion revascularization.
  
  
  RESULTS
  The patients were (61 ± 5) years old. Coronary angiography showed 5 patients had triple vessel lesions. There were 9 target lesions on left anterior descending artery. There were 3 (27.3%) severe calcified, 4 (36.4%) chronic total occlusion, and 4 (36.4%) diffused long lesions. Reasons for emergent CABG were dissection (n = 5, 45.5%), perforation (n = 3, 27.3%), failure to sufficient predilation (n = 1, 9.1%), acute closure (n = 1, 9.1%) and stent loss (n = 1, 9.1%). The average duration of follow-up was (47 ± 33) months. During in-hospital follow-up, there were 1 (9.1%) cardiac death and 2 (18.2%) Q wave myocardial infarction. During follow-up after hospital discharge, 1 patient (9.1%) died of kidney failure, and there was no rehospitalization due to cardiac events.
  
  
  CONCLUSIONS
  Emergent CABG after failed PCI often happened in patients with complex coronary lesions. The long term outcome of patients requiring emergent CABG after failed PCI was favorable in this cohort.
