title: Evaluation of left atrial function via two-dimensional speckle-tracking echocardiography in patients with coronary artery ectasia.
abstract: BACKGROUND
  Coronary artery ectasia (CAE) is a segmental dilation of an epicardial coronary artery. Our aim was to evaluate the left atrial (LA) function in patients with CAE.
  
  
  METHODS
  Twenty-seven consecutive patients with CAE and 33 subjects without significant coronary artery disease were included in our study. LA function was evaluated with two-dimensional speckle-tracking echocardiography (2DSTE).
  
  
  RESULTS
  The systolic, early diastolic and late diastolic strains and strain rates were not statistically significantly different between the two groups.
  
  
  CONCLUSIONS
  Our findings demonstrated that LA function may not be affected by CAE when assessed with 2DSTE. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound 45:231-237, 2017.
