title: Exercise-induced vasospastic angina after left atrial catheter ablation: a case report.
abstract: BACKGROUND
  Left atrial catheter ablation (LACA) is routinely used in the management of recurrent atrial fibrillation.
  
  
  METHODS
  We report a patient suffering from vasospastic angina 2 months after a LACA procedure. Typical clinical symptoms, ST-segment changes during exercise test and successful treatment with nicorandil led to the diagnosis. According to our hypothesis, destruction of autonomic ganglia in the left atrium and resulting autonomic nerve tone imbalance might be the main determinants that have caused this phenomenon.
  
  
  CONCLUSIONS
  Coronary spasms even weeks after LACA should draw attention to a possible association with the procedure.
